A brief introduction to the assembly and assembly process of PCB flip chip Before discussing the assembly and assembly process of flip chips for PCB boards, it is necessary to understand what devices are called flip chips? In general, such devices have the following characteristics: 1. The base material is silicon; 2. Electrical surface and welding convex on the lower surface of the device; 3. The ball spacing is generally 4-14mil, the ball diameter is 2.5-8mil, and the overall size is 1-27mm; 4. After assembling on the substrate, you need to fill the bottom. In fact, the reason why the flip chip is called "flip" is relative to the traditional metal Wire Bonding connection method (Wire Bonding) and the process after planting the ball. The electrical side of the traditional chip connected to the substrate through metal wire bonding is facing up, and the electrical side of the flip chip is facing down, which is equivalent to turning the former over, so it is called "flip chip". After the chip is planted on the Wafer, it needs to be turned over and fed into the placement machine for easy mounting, and because of this flipping process, it is called "flip chip". First, PCB board with flip chip assembly process In the semiconductor back-end assembly plant, there are now two methods of module assembly. In the two reflow processes, SMT components are first assembled on a separate SMT line consisting of a screen press, a SMT mounter and the first reflow. The partially assembled modules are then processed through a second production line, which consists of PCB flip chip mounters and reflow furnaces. The bottom fill process is completed in a dedicated bottom fill line, or combined with a PCB flip chip line. Second, PCB board with flip chip assembly process introduction Compared with other IC devices, such as BGA, CSP, PCB flip chip assembly process has its special, the process introduces the flux process and the bottom filling process. Because of the flux residue (impact on reliability) and the danger of bridging, the PCB board is not an acceptable assembly method to mount on the solder paste with flip chips. In the industry, no cleaning flux was introduced, and the chip dipping flux process became a widely used welding aid technology. At present, the main alternative method is to use no-wash flux, dip the device in the flux film, dip the device ball into a certain amount of flux, and then mount the device on the substrate, and then reflow welding; Alternatively, the flux is pre-applied to the substrate, and then the device is mounted and reflow welded. The flux plays the role of fixing the device before reflow, and wetting the welding surface enhances the weldability during reflow. After the PCB board is welded with a flip chip, a glue (generally epoxy resin material) needs to be filled between the bottom of the device and the substrate. Bottom fill is divided into liquid and non-liquid (No-follow) bottom fill based on the "capillary flow principle". Flip chip assembly process flow (non-fluid bottom fill) The PCB flip-chip assembly process is for C4 devices (the device welding salient material is SnPb, SnAg, SnCu or SnAgCu). Another process is to use anisotropic conductive adhesive (ACF) to assemble PCB flip chips. The conductive adhesive is applied to the substrate in advance, and the device is mounted on the substrate with a higher pressure at the sticker head. At the same time, the device is heated to make the conductive adhesive solidify. This process requires a very high accuracy of the mounter, and a high pressure and heating function of the mounter head. For the assembly of non-C4 devices (whose convex material is Au or other), the trend is to use this process. Here, we mainly discuss the C4 process, and the following table lists several ways of Bumping PCB boards with flip chips and connecting on the substrate. A brief introduction to the assembly and assembly process of PCB flip chip The flip chip geometry of PCB board can be described by a "small" word: small ball diameter (as small as 0.05mm), small ball spacing (as small as 0.1mm), and small overall size (1mm2). In order to obtain satisfactory assembly yield, the mounting equipment and its process has brought challenges, with the reduction of the diameter of the welding ball, the mounting accuracy requirements are getting higher and higher, and the accuracy of 12μm or even 10μm is becoming more and more common. The graphics processing ability of the camera is also very critical, and the small ball diameter and small ball spacing require a higher pixel camera to process. Over time, the size of high-performance chips continues to increase, the number of Solder bumps increases, the substrate becomes thinner and thinner, and the bottom filling becomes necessary to improve product reliability.

Aluminium PCB – Hitech Circuits Co., Limited, from China 1. What’s Aluminium LED PCB? Aluminum LED PCB substrate is a metal - based copper-clad sheet with good heat dissipation. A single panel is generally composed of three layers of structure, namely the circuit layer (copper foil), insulation layer and metal base layer. It is commonly found in LED lighting products. There are two sides, the white side is used to weld the LED pins, and the other side is the natural color of aluminum, which is usually coated with heat-conducting gel and then in contact with the heat-conducting part. Among all metal core PCBS, Aluminum LED PCB is the most common type. The base material consists of an aluminum core and standard FR4. It features a thermal cladding that dissipates heat in an efficient manner while cooling components and improving the overall performance of the product. Currently, aluminum-backed PCBS are considered solutions for high power and tight tolerance applications. 2. Aluminum LED PCB with Copper Layer, Dielectric Layer & Aluminum Layer Aluminum LED PCB has a similar layout to any other printed circuit boards with copper layer(s), solder mask layer(s) and silkscreen(s). Instead of having a fiberglass or plastic substrate, Aluminum LED PCB is made from metal core substrate, which consists of copper layer, dielectric layer and aluminum layer. This substrate is called as Aluminum based copper clad laminate (CCL). The glass reinforced and ceramic filled dielectric layer in-between copper layer and aluminum layer is very thin, but plays a very important role of electric insulation and thermal conductivity (because of minimum thermal resistance) from copper layer to aluminum base. The copper is etched into conductors and metal base is to withdraw thermal (/heat). The superior heat transfer capacity of Aluminum-based PCB helps cooling components while eliminating problems associated with managing fragile ceramics. 3. Thermal conductivity of Aluminium LED PCB The general thermal conductivity of Aluminum LED PCB is 0.3, 0.6, 1.0, 1.5, 2.0, 3.0, 5.0, 122W/m.k, etc., among which 0.3-1.0w /m.k is the general conductive Aluminum LED PCB, 1.5W/m.k is the middle conductive Aluminum LED PCB, 2.0-3.0w /m.k is the high conductive Aluminum LED PCB. 5.0W/m.k is thin abasal substrate, and 122W/m.k is ultra-high conductivity Aluminum LED PCB, also known as ALC Aluminum LED PCB. At present, the common Aluminum LED PCB on the market has a thermal conductivity of 1.0, 1.5, 2.0W/m.k high conductivity type Aluminium LED, wherein the thermal conductivity of 1.0W/m.k Aluminum LED PCB is called general Aluminum LED PCB, its insulation layer is composed of epoxy glass cloth bonded sheet; Aluminum LED PCB with thermal conductivity of 1.5W/m.k is called high heat dissipation Aluminum LED PCB, and its insulation layer is composed of epoxy resin or other resins with high thermal conductivity; The Aluminum LED PCB with a thermal conductivity of 2.0W/m.k is called the Aluminum LED PCB for high-frequency circuit, and the insulating layer is composed of polyolefin resin or Polyimide resin glass cloth bonded sheet. The thermal conductivity of Aluminum LED PCB varies according to the copper layer in the circuit. Different processes produce different levels of thermal conductivity. We currently support Aluminum based CCLs from Ventec, GDM and BoYu with thermal conductivity from 1.0 ~ 7 W/m•K. The Aluminum LED PCB prices of Ventec is much higher than that with GDM and BOYU since material cost, and the prices of high thermal conductivity is higher than low thermal conductivity. Hitechpcb provides a wide range of electrical and thermally conductive interface pads, thermally conductive gap filler, thermal phase change materials and thermally conductive electrically insulating materials, as well as specialized equipment for high volume Aluminum LED PCB manufacturing. Choosing Hitech Circuits PCB as your Aluminum LED PCB supplier, just send your Gerber files and fabrication notes to us, we will deliver qualitied PCB boards to you on time. 4. Dielectric Constant of Aluminium LED PCB The dielectric constant of Aluminum LED PCB substrate is a special detection method for Aluminum LED PCB. It is a variable Q value series resonance method through the measurement of dielectric constant and dielectric loss factor. The sample and tuning capacitor are connected in series to the high frequency circuit to measure the series circuit The principle of Q value. The performance of Aluminum LED PCB includes requirements such as peel strength, surface resistivity, minimum breakdown voltage, dielectric constant, flammability and thermal resistance. 5. Aluminum LED PCB with White Solder Mask The retail price of Aluminum LED lights has dropped dramatically in recent years, while the energy efficiency and brightness of LED lights have improved. These technological advances have led some to predict annual growth of 45% over the next five years. With the development of the LED industry, the demand for LED PCBS and solder masks is also increasing. Solder shield is a protective coating applied to exposed printed circuit boards. The exposed PCB board is covered with a mask to prevent accidental solder bridging during PCB assembly and to protect the PCB from the environment. Solder masks are traditionally green, and are expected to withstand the high temperatures that occur in reflow soldering, as different colors such as blue, red, or black will occasionally appear. Increased production of Hitch Aluminum LED PCB requires increased whiteness and color stability of the mask. Aluminum LED PCB commonly used LPI welding color is white and black, of which white welding color is the most commonly used to achieve high brightness and perfect light reflection. White Aluminum LED PCB ensures no darkening and will not affect the color temperature of LED smd. At the same time, it also helps to increase the life of LED applications. Looking for reliable Aluminum LED PCB suppliers, Hitech is a good choice. 6. Classification of Aluminum LED PCB Substrate Aluminum LED PCB-based copper clad plates are divided into three categories: The first is the universal aluminum-based copper clad plate, the insulation layer is composed of epoxy glass cloth bonded sheet; The second is the high heat dissipation aluminum-based copper-clad plate, the insulation layer is composed of high thermal conductivity epoxy resin or other resins; Third, high frequency circuit aluminum base copper plate, insulation layer by polyolefin resin or Polyimide resin glass cloth bonded sheet. The biggest difference between aluminum clad copper plate and conventional FR-4 clad copper plate is heat dissipation. Compared with 1.5mm thickness of FR-4 clad copper plate and aluminum clad copper plate, the former thermal resistance of 20 ~ 22 ℃, the latter thermal resistance of 1.0 ~ 2.0℃, the latter is much smaller. 7. Aluminum LED PCB Performance: (1) Heat dissipation Many double panel, multi - layer plate high density, power, heat distribution is difficult. Conventional printed board substrates such as FR4, CEM3 are bad conductors of heat, insulation between layers, heat does not escape. Local heating of electronic equipment is not excluded, leading to high temperature failure of electronic components, and Aluminum LED PCB can solve this problem of heat dissipation. (2) Thermal Expansibility Thermal expansion and cold contraction is the common nature of substances, and the coefficient of thermal expansion of different substances is different. Aluminum based printed board can effectively solve the problem of heat dissipation, so that the printed board components of different substances on the thermal expansion and contraction problem, improve the durability and reliability of the whole machine and electronic equipment. Especially solve SMT (surface mount technology) thermal expansion and shrinkage problems. (3) Dimensional stability Aluminum-based printed boards are obviously much more stable in size than those made of insulating materials. Aluminum base printed board, aluminum sandwich board, heating from 30℃ to 140~150℃, the size change is 2.5~3.0%. (4) Other reasons Aluminum based printed board, with shielding effect; Instead of brittle ceramic substrate; Safe use of surface mounting technology; Reducing the real effective area of the printed board; Instead of radiator and other components, improve the heat resistance and physical properties of products; Reduce production costs and labor. 8. Why choose Aluminum LED PCB from Hitechpcb? What are the advantages of Aluminum LED PCB? (1) Good heat dissipation performance: Aluminum LED PCB can reduce the thermal resistance to the minimum, has a smaller thermal resistance, thermal expansion coefficient is closer to copper foil, so that Aluminum LED PCB has excellent thermal conductivity and heat dissipation performance, reduce the module operating temperature, prolong the service life. High current load: Using the same thickness, the same line width, Aluminum LED PCB substrate can carry higher current. (2) Good machinability: can replace ceramic substrate, better mechanical endurance. At the same time, high strength and toughness, can realize large area printed board manufacturing and component mounting. (3) Good electromagnetic shielding: In order to ensure the performance of electronic circuits, some components of electronic products need to prevent electromagnetic radiation and interference. Aluminum LED PCB can act as a shield plate, play the role of shielding electromagnetic wave (4) Environmental protection: The Aluminum LED PCB used in the raw material is non-toxic and can be recycled. Meet RoHs requirements. (5)Light weight: Aluminum LED PCB has a surprisingly light weight with excellent strength and elasticity, which is very convenient. Hitech Circuits can provide high quality and affordable Aluminum LED PCB products for you. 9. Technical requirements for Aluminum LED PCB The main technical requirements are: 1. Dimensional requirements: including panel size and deviation, thickness and deviation, perpendicularity and warpage; Appearance, including cracks, scratches, burrs and delimitation, aluminum oxide film, etc. 2. Performance requirements, including peel strength, surface resistively, minimum breakdown voltage, dielectric constant, combustion and thermal resistance requirements. 10. Special test method for Aluminum-based copper clad plates One is the measurement method of dielectric constant and dielectric loss factor. It is the series resonance method with variable Q value. The sample and tuned capacitor are connected to the high-frequency circuit in series to measure the Q value of the series circuit. The other is the measurement method of thermal resistance, which is calculated by the ratio of temperature difference and heat conduction between different temperature measurement points. 11. The Aluminum LED PCB manufacturing process in Hitechpcba (1)Substrate cutting a. cutting process: material → cutting b. Note: ① Check the size of the first piece; ② Pay attention to Aluminum surface scratching and copper surface scratching; ③ Pay attention to the layering of the board edge and the tip. (2)Plate drilling a, drilling process: pin → drilling → inspection plate b, matters needing attention: ① check the number of drilling holes, the size of the empty chestnut chain; ② Check the plate burr, hole deviation; ③ Avoid scratching the substrate; ④ Check and replace the drill nozzle. (3) Imaging transfer a, graphic imaging process: grinding plate → film → exposure → development b, precautions: ① Check whether there is an open circuit after development; ② Pay attention to the poor line caused by the board wipe; ③ There can be no air residual exposure to prevent poor exposure; ④ Whether there is deviation in developing counterpoint; ⑤ After exposure, the development should be done at rest for more than 15 minutes. (4)Solder mask and Silkscreen process a, kill row silk printing resistance welding, character process: screen printing → pre-baking → exposure → development → character b, matters needing attention: ① Check whether there is foreign body on the board; ② Pay attention to the cleaning of the net board; ③ Pre-bake for more than 30 minutes after screen printing, to avoid bubbles in the line; ④ Pay attention to the thickness and uniformity of screen printing; ⑤ After the pre-baked plate to completely mutual cooling, avoid touching film or damage to the ink surface gloss. (5)E-test or flying probe test a, test process: line test → withstand voltage test b, precautions: ① How to distinguish after the test how to store qualified and unqualified products. (6)FQC, FQA, packaging, shipping a. Process: FQC→FQA→ Packaging → shipping b. Note: ① FQC should pay attention to the confirmation of the appearance of the finished Aluminum LED PCB in the process of eye inspection and make a reasonable distinction; ② FQA does spot check and verify the inspection standards of FQC; ③ We should confirm the number of packages to avoid mixed plates, wrong plates and package 12. Application of Aluminum LED PCB 1. Audio devices: input, output amplifier, balance amplifier, audio amplifier, preamplifier, power amplifier. 2. Power Supply: switching voltage regulator, DC/AC converter, SW voltage regulator, etc. 3. Communication electronic equipment: high frequency amplifier, filter, transmitter circuit 4. Office automation equipment: motor drive, etc 5. Automobile: electronic regulator, ignition device, power controller, etc. 6. Computer :CPU board, floppy disk drive, power equipment, etc. 7. Power module: converter, solid relay, rectifier bridge, etc 8. Lamps and lighting: A variety of colorful LED energy-saving lamps are well received by the market, and Aluminum LED PCB used in LED lights has also begun to be applied on a large scale. 13. Aluminum LED PCB Storage Conditions Aluminum LED PCB are generally stored in a dark and dry environment. Most Aluminum LED tube lighting metal core pcb are prone to dampness, yellowing, and blackening. Generally, they should be used within 48 hours after opening the vacuum package. 14. Specification for the manufacture of Aluminum LED PCB a. Aluminum LED PCB is often used in power devices, power density is high, so the copper foil is thicker. If copper foils over 3oz are used, the etching of thick copper foils requires engineered line width compensation, otherwise the line width will be out of tolerance after etching. b. The aluminum base surface of aluminum substrate must be protected by protective film in advance during PCB processing, otherwise, some chemicals will etch the aluminum base surface, resulting in appearance damage. And the protective film is easy to be hurt, resulting in gaps, which requires the whole PCB processing process must be inserted. c. The hardness of the milling cutter used by the glass fiber board gong board is relatively small, and the hardness of the milling cutter used by the aluminum substrate is large. In the process of manufacturing glass fiber board milling cutter speed, while the production of aluminum substrate is at least two thirds slower. d, computer milling glass fiber board is just the use of the machine's own cooling system, but the processing of aluminum substrate must be in addition to alcohol heat dissipation for the gong head. 15. Aluminum LED PCB circuit fabrication (1) Mechanical processing: Drilling of aluminum substrate can be done, but no burr is allowed on the edge of the inner hole after drilling, which will affect the pressure test. Milling the shape is very difficult. And punching shape, need to use advanced mold, mold production is very skilled, as one of the difficulties of aluminum substrate. After shape punching, the edge should be very neat, without any burr, and do not hurt the welding resistance layer on the edge of the plate. Usually the use of soldier die, hole from the line, shape from the aluminum surface, circuit board punching force is cut down, and so on are skills. After punching the shape, the warpage of the board should be less than 0.5%. (2) The whole production process is not allowed to wipe the aluminum base surface: aluminum base touch, or by a certain chemical will produce surface discoloration, blackening, which is absolutely unacceptable, re-polishing aluminum base some customers do not receive, so the whole process does not touch the aluminum base surface is one of the difficulties in the production of aluminum base plate. Some enterprises use passivation process, some in hot air leveling (spray tin) before and after each pasted protective film. (3) Over-high voltage test: the aluminum base board of the communication power supply shall be tested at 100% high voltage. Some customers require direct current or alternating current. The voltage shall be 1500V or 1600V, and the time shall be 5 seconds or 10 seconds. Dirt on the board, holes and aluminum edge burr, line saw tooth, damage to any little insulation layer will lead to high voltage test fire, leakage, breakdown. Pressure test board stratification, foaming, are rejected. For further details freely contact Cynthia at [email protected] [a]https%3A%2F%2Fwww.hitechpcba.com%2Faluminium-led-pcb[/a]

What is big batch PCB assembly? Big batch PCB assembly is an assembly process where you will assemble 10,000 or more PCBs in a specific period of time. The main processes you will use to assemble PCBs in large quantities are design for manufacturing and design for testing. What are the advantages of using big batch PCB assembly? PCB assembly process With applications in mind, big batch PCB assembly will provide you with numerous industrial and personal benefits. This is why electronic OEM prefer to use it in most of their applications. The following are the main advantages of using mass printed circuit components: Rapid design and prototyping process Since you will be mass-producing or manufacturing printed circuit boards, you must assemble them uniformly. By simply creating a design and a prototype that works for each PCB, you can save a lot of time. Short production cycle Since the production process is fully automatic, you will also save time in the production of numerous PCBS. It all starts with the design and prototyping phase, which you'll do with the help of software and machines. Production consistency You will also have a very uniform production process because most of the details are predetermined before implementation. Once production begins, all manufacturing specifications will follow uniform specifications for all printed circuit boards. Quality consistency Since you will be producing all PCBs to similar specifications, you will automatically get consistent quality throughout the production process. In other words, you should rest easy knowing that you will have consistency across all printed boards. First-class cost performance This is the most convenient model for the cost of producing printed circuit boards because you can do everything very consistently. Here, you will buy all the materials in bulk and produce them in a short time using similar machines. Improve the market's ability to time You will be able to produce large number of printed circuit boards in a very short time, thus giving you the advantage in the market. In other words, you will have a steady supply of on-demand printed circuit boards, giving you the advantage in the market. Do you have lead-free mass PCB assembly? Yes, we care about the health of our users and the health of the environment. We are aware of the harmful or negative effects that lead emissions can have on users and the environment.That's why we eliminate lead from production materials. It is of great benefit to protect people's health and eliminate environmental pollution. What is the testing protocol for mass PCB assembly? As long as you have completed the process of producing printed circuit boards, you must ensure that they run well. Existing testing protocols will help ensure that large volumes of PCBs are in perfect working condition. Here are the main test protocols you can perform on a high volume printed circuit board: Automated Optical Inspection (AOI) You will use Automated Optical Inspection (AOI) tools to accurately and efficiently detect production errors in big batch PCB assembly. It has cameras and image-processing software that can identify assembly errors and relay information for further action. It is the best tool you will use for better error detection than visual inspection. Solder Paste Inspection (SPI) After you have finished printing with the paste printer, you must pass it through the paste inspector. The SPI machine has a camera and communication system equipment that can examine every detail of the solder paste.It compares these details to the Gerber file and reports any kind of inconsistency. In-Circuit Test (ICT) In-Circuit Test, you can use the most detailed test methods to check the quality and integrity of the PCB.Here, you will have to take personal initiative and use online testing software to check the quality of your PCB.You will use the machine to detect errors in the PCB for correction. Functional Circuit Test Here, you will use a computer with test pins or test probes to test the functional integrity of the PCB. You can tell if the board passes the test simply by comparing the results to the design specifications. X-ray Examination You will use X-ray inspection to detect welding problems on the PCB that are not visible to the human eye. Here, you do not have to cut through the circuit board to see the welding quality on the printed circuit board. You'll use X-ray inspection protocols to detect errors in components and soldering on circuit boards. Do you have a custom mass PCB assembly? Yes, we do customize mass printed circuit boards. You can order the most unique types of printed circuit boards and we will produce them according to your needs. We'll review your design, create a prototype, and then test how it works. Once we confirm that it is working well according to the design details, we will proceed with the production process. How does small batch PCB assembly compare to large batch PCB assembly? On the production scale, you can choose between large batch PCB assembly or small batch PCB assembly. Mass PCB assembly is the process by which you assemble 10,000 or more printed circuit boards. It is a mass production or assembly system that can mass produce PCBs in a short period of time. On the other hand, you can choose to assemble PCBs in small batches for small scale production or assembly of PCBs. In other words, you will produce a very small number of printed circuit boards of 250 or less. In large and small batch PCB assembly, the assembly process will remain the same. In addition, you will use similar detection techniques for high - and small-lot PCB assemblies. What are the main capabilities of mass PCB assembly? Well, when you're looking for a good large volume PCB assembler, there are some special features. This means that they must have the specific resources that you will use in the PCB assembly process. The following are the main functions that must be available for mass PCB assembly. Manufacturing capacity It is important to have a manufacturer that can use both surface mount technology and through-hole technology. You must find a manufacturer with sufficient knowledge and experience in surface mount technology and through-hole technology. Fast turnaround time You should also have a manufacturer that can produce large number of PCBs in a very short time. In other words, you don't have to wait longer to get the printed circuit board you ordered. Welding capacity In this case, the key point you must pay close attention to is the ability to weld manually and by machine. Your manufacturer should be able to perform both hand and machine welds. Quality compliance You should also know that the quality of the printed circuit board is a top priority when it comes to durability and safety. Here, your manufacturer must have the knowledge to read the list of materials and identify the right quality products. Test method You must also choose a manufacturer that has knowledge of all test machines and printed circuit boards. In other words, after production, your supplier must test all printed boards accordingly before providing PCBs. What are the applications of mass PCB assembly? You will be mass-producing large volume PCB assemblies of different equipment at high rates. If you want to enter the PCB production market, you must have knowledge of mass PCB assembly. Here are some industries that require big batch PCB assembly. The communications industry mass-produces communications equipment Military or defense industry Automobile industry Aviation industry You will be using big batch PCB assembly in an industry where big batch production, consistency, and consistency are important. What is the cost of mass PCB assembly? Well, the cost of mass-producing printed circuit boards is fairly affordable. Here, you will apply economies of scale in the production process, thereby reducing the cost of producing PCBs. In addition, other factors that affect cost such as quality and size will also play an important role. You will spend more on high quality and larger PCB materials, increasing production costs. Typically, the amount you will spend usually depends on the design specifications of your PCB. How safe is the mass PCB assembly process? Well, most of the manufacturing process for big batch PCBs is highly automated. In other words, there was little human involvement other than the design and programming of the machine. In addition, we eliminate any material that would suspend harm to the environment and users. This makes mass PCB assembly one of the safest modes for producing printed circuit boards. Do you provide both THT and SMT in big batch PCB assembly? Yes, we have both through-hole technology and surface mount technology for PCB assembly. These are the main manufacturing methods we use to produce high quality printed circuit boards. You will choose among these manufacturing modes based on the design and application specifications. Is there turnkey assembly for large volume PCB assembly? Of course, our production system is capable of handling very large volumes of turnkey PCBs. You'll find products that you can buy in bulk to meet your production needs. Here, we will be responsible for every step of production from design, inspection, prototyping and assembly. What is the turnaround time for mass PCB assembly? You should rest easy knowing that your production specifications will be met as planned. This includes time for all production specifications and you will accordingly meet all your market needs. What are the quality certifications for mass PCB assembly? As we mass-produce printed circuit boards, we also ensure consistent quality. This means that you will get the highest quality printed circuit boards in large quantities at an affordable price. Our quality meets and exceeds international quality standards, namely: Comply with IPC quality standards such as IPC-WHMA-A-610 and IPC-CC-830B ANSI/AHRI quality standards, such as ANSI/J-STD-001 -- Class II and III only RoHS quality certification UL quality standard CE quality standard What to consider when choosing big batch PCB assembly services? You'll see the manufacturing capabilities of high-volume PCB assemblers. Here are the main factors that you must pay close attention to: Manufacturing and service capabilities QC Years of manufacturer experience Customization capability Turnaround time Responsiveness and flexibility Delivery service Why is it difficult to scale up from prototype to high-volume assembly? Scaling up from low-volume to high-volume PCB assembly can prove to be a difficult and painful process. Here are the main reasons why this can pose a difficult challenge. You must change design files and formats to meet new design requirements You may also lack the correct type of machine for the new specification You may also have to change components that will be tied to the PCB You may also have to change the entire design to accommodate the new specifications How do you simplify the transition from prototyping to high-volume PCB assembly? Despite the difficulties, you should rest easy knowing that you can easily complete the process. The best way is to choose the best prototype CM that can collaborate all the details accordingly. It will help remove obstacles that can cause confusion and make the process difficult. At Hitech Circuits, we will help you with the PCB fabrication and PCB assembly process.

LED PCB Assembly – Hitech Circuits Co., Limited

$1.00

LED PCB Assembly – Hitech Circuits Co., Limited What is the LED Circuit Board assembly? Generally, LED PCB assembly is considered to be a circuit board that has the LED components soldered to it. The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. Not all the PCB products can be used in Led industry, as an LED PCB is easy to create a high volume of heat, but making it hard to cool with traditional methods. For this reason, metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat, especially aluminum pcb is often used to fabricate PCB for LED lights. We’ve had great LED PCB assembly experiences with top LED chips to brand such as Cree, Luxeon, Osram, Nichia, Lumileds, MLS, EVERLIGHT, Samsung, LG, Seoul., etc. PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility. Application of LED PCB Assembly Hitechpcba serves customers in different industries, providing highly reliable and innovative LED PCBs for various applications: • Horticulture light LED PCB Assembly • LED controller PCB Assembly • Computer LED display and indicators • LED lights PCB Assembly for medical use • Automotive LED PCBs Assembly include PCBs for brake lights and headlights • Street lighting LED PCB Assembly • Flashlights and camping accessories • Traffic light PCB Assembly • Commercial lighting LED PCB Assembly LED PCB Assembly specification Number of layers for LED PCB These layers are made up of aluminum and magnesium, but now have Copper base material and Ceramic base materials for LED PCB industry, we can meet it. Aluminum LED PCBs stand out among other PCBs because it has a good insulation characteristic and has a better machinery performance, the cheap cost is one important factor too. Types of layers for LED PCB Assembly Normally, the base layer is made using aluminum alloy metal. This aluminum alloy substrate used in making the base makes it ideal for through-hole technology which transfers and dissipates heat. A thermal insulation layer is made using some ceramic polymer which has good viscoelasticity characteristics. It is highly heat resistant and protects the PCB against heat and mechanical stress. The circuit layer, which is covered by a copper foil which can range from one to ten ounces. LED Board type- single or in panel Some boards are shapeless. For this reason, LED PCB panels are used. This reduces time, labor production and testing time. Some LED PCB Assembly is done on a single board while others are done on panel boards. LED PCB Assembly Process Roughly, the PCBA process can be divided into theses phases: soldering paste printing > SMT (surface mounted technology) > reflow soldering > AOI (automated optical inspection)> THT (through-hole technology) > wave soldering > touch-up and cleaning > IC-programming > FCT (functional tests) > aging testing. Below we show you the process. Step1. Summarizing Project Information Before contacting your supplier, make sure you have all the project information. Suppliers will need info following for quoting LED PCB assembly: Gerber BOM LED PCB specification Quotation quantity Once you have gathered these information, you can contact us and request for a quote. Of course, you can also provide the schematic, LED PCB Assembly pictures and even samples to us. The more details they have, the more accurate the supplier’s quotation will be. Step2. Discussion and details about custom LED PCB Assembly Different projects will have different requirements. Remember the special requirements mentioned in step 1? That’s going to be the focus of this session. Equipment and engineering capacity will not be identical between suppliers. Make sure your supplier has the equipment to produce and assemble major components and the corresponding testing capabilities. For example, some vendors don’t have X-ray testing equipment, which means they can’t check the mount quality of BGA chips. Outsourcing this step will increase risk and cost. That’s what you don’t want. Also, pay attention to time taken by the supplier to quote. Motherboards often contain hundreds or even thousands of components, and they are supplied by different manufacturers. To ensure the quality of the components, the supplier sourcing team will make multi-inquiries from these manufacturers or authorized suppliers to match customer’s requirement, which usually takes 2-3 business days, and even longer for some scarce chips. Therefore, if your project is complex and the supplier quotes you within few hours, double check with them. Step3. Sample and feedback After confirming the PI, the supplier will usually provide pre-production samples for your approval. At the same time, the supplier will also confirm with you the logistics plan of the bulk goods. Make sure they understand your shipping requirements, including details on packaging, customs clearance, taxes, etc. For us to have a successful LED PCB Assembly process, its functions must be defined. Compliance requirement is defined to reduce the effect when components are selected. The Bill of Materials is then generated from the information installed on the LED PCB. All this information is used to assemble components which are identified from MOB to the LED PCB.

HDI PCB & High Interconnect PCB Manufacturing(from Hitech Circuits Co., Limited)

$1.00

HDI PCB & High Interconnect PCB Manufacturing(from Hitech Circuits Co., Limited) What is a high density PCB board (HDI PCB)? The HDI board is based on the traditional double panel as the core board, which is made by continuously accumulating. This circuit board made by a continuous layer is also called the Build-Up Multilayer (BUM). Compared with the traditional circuit board, the HDI circuit board has the advantages of "light, thin, short, small". The electrical connection between HDI's plate layer is achieved by conductive pores, buried holes, and blind holes. Its structure is different from ordinary multi -layer circuit boards. A large number of blind holes are used in HDI boards. HDI PCB uses laser direct drilling, and standard PCB usually uses mechanical drilling, so the number of layers and high width ratio often decreases. HDI includes the use of fine features or signal traces and spaces of 0.003” (75 µm) or less and laser-drilled blind or buried microvia technology. Microvias allow the use of micro-interconnects from one layer to another within a PCB utilizing a smaller pad diameter creating additional routing density or reducing form factor. High-density interconnect (HDI) PCBs are characterized by finer lines, closer spaces, and more dense wiring, which allow for a faster connection while reducing the size and bulk of a project. These boards also feature blind and buried vias, laser ablated microvias, sequential lamination, and via in-pads. As a result, a HDI board can house the functionality of the previous boards used. HITECH CIRCUITS is an HDI PCB manufacturer and provider in Shenzhen, China supports HDI PCB prototype and mass production with less expensive price and quick-turn lead time. Customers from a variety of industries we serve have a common that have high expectations in quality, reliability and on-time delivery in HDI PCB production. Our quality is not afterthought, but built into each process from front-end to fabrication and shipping. HDI PCB's advantages 1. Reduce PCB cost: When the density of PCB increases beyond the eight-layer board, it will be manufactured in HDI, and the cost will be lower than that of traditional complicated press-forming process. 2. Better reliability: Due to the thin thickness and the aspect ratio of 1:1, the micropores have higher reliability when transmitting signals than ordinary through holes. 3. Improves thermal properties: The insulating dielectric material of the HDI board has a higher glass transition temperature (Tg) and therefore has better thermal properties. 4. Improve RF interference / electromagnetic interference / electrostatic discharge (RFI / EMI ) 5. Increase design efficiency: Micro-hole technology allows the circuit to be arranged in the inner layer, so that the circuit designer has more design space, so the efficiency of the line design can be higher. HDI PCB Manufacturing Process The overall process for manufacturing HDI PCB is essentially the same as for fabricating other PCB board, with notable differences for PCB stack-up and hole drilling. Since HDI boards generally require smaller drill holes for vias, laser drilling is usually required. Although laser drills can produce smaller and more precise holes, they are limited by depth. Therefore, a limited number of layers can be drilled through at a time. For HDI boards, which are invariably multilayer and may contain buried and blind vias, multiple drilling processes may be required. This necessitates successive layer boding to achieve the desired stack-up or sequential lamination cycles. Not surprisingly, this can significantly increase PCB manufacturing time and cost. HDI PCB fabrication is an advanced technology and therefore requires expertise along with specialized equipment like laser drills, laser direct imaging (LDI) capability, and special clean room environments. In order to efficiently manufacture high-quality and reliable HDI PCB products, you must understand the HDI board manufacturing process and coordinate with your HDI PCB supplier to implement good DFM (Design for Manufacturability) for HDI layout design. Therefore, not all board factories have the ability to do the HDI, but Hitechpcb can, we will be here to support our customer needs. -Consumer Driven Technology The via - in - pad process supports More technology on fewer layers, proving that bigger is not always better. Since the late 1980's we have seen video cameras using cartridges the size of a novel, shrink to fit in the palm of your hand. Mobile computing and work at home have further promoted technology to make the computer faster and lighter, allowing consumers to do remote work from anywhere. HDI technology is the main reason for these changes. The products do more, weigh less, and their bodies are smaller. Professional equipment, mini components and thinner materials reduce the size of electronic equipment, while expanding technology, quality and speed. -Via in Pad Process The inspiration from the surface installation technology pushed the restrictions of BGA, COB and CSP to a smaller square surface inch. The via in pad can be placed in the surface of flat land through the cushion process. The via is plated and filled with conductive or non-conductive epoxy resin, and then close and plat it to make it almost invisible. It sounds simple, but there are eight steps to complete this unique process. Professional equipment and well -trained technicians followed closely to achieve perfect hiding. -Via Fill Types There are many different types of via fill materials: non -conductive epoxy, epoxy, copper filling, filling and electrochemical coating. All this leads to via buried in a flat land, and the land will be fully solders as normal land. Vias and mricrovias are drilled, blind or buried, plated, and then hidden under the SMT land. Processing vias of this type of Vias requires special devices and takes time. The process time of multiple drill cycles and controlling deep drills has increased. -Cost Effective HDI Although the size of some consumer products is reduced, quality is still the most important factor for consumers. Use HDI technology during the design process, you can reduce the 8-layer through-hole PCB to a 4 layer HDI Microvia technology packed PCB. The elaborate HDI 4-layer PCB wiring function can achieve the same or better functions as standard 8-layer PCB. Although the Microvia process has increased the cost of HDI PCB, the appropriate design and decrease of layers of counting reduces the cost of the ingredients of the material, and the layer count is large. -Laser Drill Technology The smallest micro-vias can provide more technologies on the surface of the plate. Using a beam with a diameter of 20 microns (1 mil), this high impact can be cut through metal and glass to produce tiny via hole. There are new products, such as uniform glass materials, and they are low -loss layer pressure plates and low -dielectric constants. These materials have high heat resistance, can be used for lead -free components, and allows smaller holes. -Lamination & Materials For HDI PCB Boards Advanced multilayer technology allows designers to add other layers to form a multilayer PCB. Use laser drills to produce holes in the inner layer, and can be coated when pressed, imaging and etching. The process of this increase is called sequential construction. Hitechpcb HDI PCB manufacturing uses solid -filled VIA can better heat management, connect stronger connection and improve the reliability of the board. The copper of the resin coating is a assistant with poor pores, with longer drilling time and thinner. Hitechpcb has ultra low contours and ultra thin copper foil, and its surface is fixed on a tiny nodule. This material has chemically treated and started chemical treatment and startup of the most fine and high quality lines and spacing technology. The dry resistance of the layer pressure plate still uses heating scroll method to apply resistance to core materials. It is now recommended to preheat the material to the required temperature before the layer pressure process of the HDI printing circuit board. The preheating of the material can better apply dry resistance to the surface of the layer pressure plate, pull less calories from the heat roll, and keep the stable export temperature of the layer made products consistent. The consistent entrance and exit temperature cause less air clips under the movie. This is essential for the breeding of fine lines and spacing. -How difficult is the HDI Printed Circuits Board? The manufacturing of the HDI PCB (High Denity PCB) is relatively difficult because it needs to use complex manufacturing technique and technology. The following is some difficulties made by HDI PCB: Multi-layer plate lamination: HDI Printed Circuits Boards are usually composed of multi-layer boards, and multi-layer boards need to be laminated. Multi-layer plates need to control parameters such as temperature, time, pressure to ensure the control quality and thickness control between multi-layer boards. Blind holes and buried holes: HDI Printed Circuits Boards need to create blind holes and buried holes, which requires technologies such as laser drilling and chemical corrosion to ensure the accuracy and quality of the hole. Impedance control: HDI Printed Circuit Boards need to control impedance, which requires fine design of the layout and circuit of the circuit board, and uses special materials and processes to achieve impedance control. Small track space manufacturing: HDI Printed Circuits Boards need to make very small spacing tracks (conductions), which requires high-precision manufacturing equipment and technologies to ensure the accuracy and quality of the circuits. -The difference between HDI board and normal PCB The HDI board is generally made of accumulation method. The more times the accumulation layer, the higher the technical grade of the board. Ordinary HDI boards are basically one accumulation. The high-end HDI uses two or more accumulated technologies, and at the same time, advanced PCB technology such as stacked holes, plating filling, and laser direct punching. When the density of PCB increases more than eight layers board, it is made by HDI, and its cost will be lower than the traditional complex compact process. The electrical performance and signal of the HDI board are higher than that of traditional PCB. In addition, HDI boards have improved better for radio frequency interference, electromagnetic wave interference, electrostatic release, and thermal conduction. High density integration (HDI) technology can make terminal product design more miniaturized, while meeting higher standards for electronic performance and efficiency. The HDI board uses a blind hole plating to perform secondary pressure, divided into one order, second order, third order, fourth, fifth order, etc. The first order is relatively simple, and the processes and processes are easy to control. The main problem of the second order is the issue of the place, and the other is the problem of punching and copper plating. There are many second order design. One is the wrong position of each order. When connecting the secondary neighborhood, it is connected to the middle layer through the wire. The method is equivalent to two first order HDI. The second is that the two order holes are overlapped. The second -order is realized by the superposition method. The processing is similar to the two first order, but there are many key points of the process. The third type is to punch perforation directly from the outer layer to the third layer (or N-2 layer). There are many different techniques from the front, and the difficulty of punching is even more difficult. In PCB proofing, HDI costs high, so general PCB proofing manufacturers are unwilling to do it. HITECHPCB can be a HDI Blind PCB board that others are unwilling to do. At this stage, the HDI technology adopted by HITECH has exceeded the highest number of layers of 20 layers; the number of blind holes is 1st to 4th; the minimum pore diameter is 0.076mm, and the process is laser drilling. HDI PCB Manufacturer & Assembly – One-stop services from China -HDI (high-density interconnection board) is a compact circuit board designed for small capacity users. Compared with ordinary PCB, the most significant feature of HDI is that the wiring density is high. HDI PCB Manufacturer & Assembly – One-stop service The HDI PCB is defined as a micro via with a hole diameter of 6 mils or less and a hole diameter of 0.25 mm or less. The contact density is above 130 points/square, and the wiring density is with a line width/pitch of 3 mil/3 mil or less. HDI PCB, the full name is High Density Interconnect PCB, it requires much higher wiring density with finer trace and spacing, smaller vias and higher connection pad density. Blind and buried vias’ design is one of their marked feature.
