PCB Assembly, PCBA factory- KingshengPCBA

PCB ASSEMBLY DEFINITION

A printed circuit board assembly (PCBA) describes the finished board after all the components have been soldered and installed on a printed circuit board (PCB). The conductive pathways engraved in the laminated copper sheets of PCBs are used within a non-conductive substrate in order to form the assembly. Attaching the electronic components to the PCBs is the concluding action to create a fully operational electronic device.

By using these types of equipment, our PCBA factory can provide high-quality, reliable PCB assemblies that meet the customer's requirements and specifications. The equipment ensures the accuracy, consistency, and repeatability of the assembly process, while also optimizing the cost and time required for PCBA production.

Equipment for Surface Mount Technology (SMT): SMT equipment is used to apply surface mount technology to the placement of electronic components on a PCB. Pick-and-place devices, solder paste printers, reflow ovens, and inspection tools are some examples of this equipment.

Equipment for through-hole technology (THT) is used to insert electronic components with leads via PCB holes. This equipment consists of inspection equipment, wave soldering machines, and selective soldering machines.

Automated Optical Inspection (AOI) apparatus: This type of apparatus is used to examine the assembly quality, identifying flaws such as soldering problems and missing or misaligned components.

X-ray apparatus: BGA and Micro-BGA assemblies are inspected using X-ray apparatus. It assists in finding flaws that are not apparent upon eye inspection.

Equipment for flying probe tests: Flying Probe Test (FPT) equipment is used to test printed circuit boards (PCBs) by passing signals across the traces to identify any problems, such as openings, shorts, or incorrect component values.

PCB Cleaning Equipment: After the PCB is assembled, it is cleaned with PCB cleaning equipment to get rid of any excess flux or impurities that can compromise the assembly's dependability and performance.

PCB Routing Equipment: Following assembly, PCBs are divided into individual components using PCB routing equipment.
