Briefly describe the basic process of PCBA patch processing <br> <br>The basic process of PCBA processing is to carry out SMT patch of components on the PCB board, DIP plug-in and realize welding. Here Hitech will briefly describe the basic process of PCBA processing for you. <br> <br>The PCBA processing process can be roughly divided into the following processes: SMT patch processing → DIP plug-in processing → PCBA testing → finished product assembly. <br> <br>1. SMT patch processing <br> <br>1). Solder paste stirring <br>The solder paste needs to be stirred before it can be used after it is taken out and thawed. <br> <br>2). Solder paste printing <br>The solder paste on the steel mesh is printed on the PCB pad by a scraper. <br> <br>3). SPI <br>SPI is the solder paste thickness detector. <br> <br>4). Mounting <br>The chip components are placed on the feeder, and the chip mounter head accurately mounts the components on the feeder on the PCB pad by identification. <br> <br>5). Reflow soldering <br>The mounted PCB board is reflowed to heat the solder paste into liquid and then cool and solidify to complete the welding process. <br> <br>6). AOI <br>AOI is automatic optical inspection, which detects the welding effect of PCB boards to eliminate bad PCB boards. <br> <br>7). Rework <br>Rework bad boards detected by AOI and manual inspection. <br> <br>2. DIP plug-in processing <br> <br>1). Plug-in <br>Insert the plug-in material on the PCB board. <br> <br>2). Wave soldering <br>The inserted board is soldered by wave soldering. <br> <br>3). Cutting the pins <br>The pins of the soldered board are generally too long and need to be cut. <br> <br>4). Post-welding processing <br>Use a soldering iron to manually solder the components. <br> <br>5). Washing the board <br>After wave soldering, the board will be dirty and needs to be cleaned with washing water and washing tank, or by machine. <br> <br>6). Quality inspection <br>Inspect the PCB board, unqualified products need to be repaired, and qualified products can enter the next process. <br> <br>3. PCBA testing <br> <br>According to different products and different customer requirements, different test methods are used to detect whether the PCBA products meet the PCBA processing requirements. <br> <br>4. Finished product assembly <br> <br>The PCBA products that have passed the test will be assembled into shells, and then tested. If the test is passed, it can be arranged for shipment. <br> <br>Hitech PCBA can provide you with high-quality SMT patch processing services, and also has rich PCBA processing experience.

Different kinds of Aluminum PCBs <br> <br>Flexible Aluminum PCBs <br>One of the newest developments in IMS materials is flexible dielectrics. These materials feature a polyimide resin system with ceramic fillers which provides excellent electrical insulation, flexibility and of course thermal conductivity. When applied to a flexible aluminum material like 5754 or similar, the product can be formed to achieve a variety of shapes and angles which can eliminate costly fixtures, cables and connectors. Although these materials are flexible, they are intended to be bent into place and remain in place. They are not suited for applications that are intended to be flexed regularly. <br> <br>Hybrid Aluminum PCBs <br>In a ‘Hybrid’ IMS construction a “Sub-assembly” of a non-thermal material is processed independently and then bonded to the aluminum base with thermal materials. The most common construction is a 2-Layer or 4-Layer Sub-assembly made from conventional FR-4. Bonding this layer to an aluminum base with thermal dielectrics can help dissipate heat, improve rigidity and act as a shield. Other benefits include: <br>Less costly than a construction of all thermally conductive materials <br>Provides superior thermal performance over a standard FR-4 product <br>Can eliminate costly heat sinks and associated assembly steps <br>Can be used in RF applications where a surface layer of PTFE is desired for its’ loss characteristics. <br>Use of component windows in the aluminum to accommodate through-hole components. This allows connectors and cables to pass connections through the substrate while the solder fillet creates a seal without the need for special gaskets or other costly adapters. <br> <br>Multilayer Aluminum PCBs <br> Common in the high performance power supply market, multilayer IMS PCBs are made from multiple layers of thermally conductive dielectrics. These constructions have one or more layers of circuitry buried in the dielectric with blind vias acting as either thermal vias or signal vias. While more expensive and less efficient at transferring heat as a single layer designs, they provide a simple and effective solution for heat dissipation in more complex designs. <br> <br>Through-Hole Aluminum PCBs <br>In the most complex constructions a layer of aluminum can form a ‘Core’ of a multilayer thermal construction. The aluminum is pre-drilled and back-filled with dielectric prior to lamination. Thermal materials or sub-assemblies can be laminated to both sides of the aluminum using thermal bonding materials. Once laminated, the completed assembly is thru-drilled similar to a conventional multilayer PCB. The plated through holes pass through the clearances in the aluminum to maintain electrical insulation. Alternatively a Copper core can allow both direct electrical connections as well as with insulated through holes. <br> <br>If you want to know ceramic PCBs, please feel freely to contact Cynthia at [email protected]
