Principle and Application of PCB and PCBA Test Racks

2 types of test racks are generally used for the PCBA production process, one is the PCB test rack, and the other is the PCBA test rack. Some consumers frequently confuse these two types, and some clients do not know what these test racks are utilized for. Let pcbandassembly introduce the concepts and uses these two examination shelfs.

PCB test racks are customized according to consumer needs and are figured out by the size of the PCB board to be generated and the place of the solder joints. It is generally comprised of epoxy resin panels, metal probes, cables, and discovery user interfaces. It is primarily used to spot the connection of the circuit card to make certain that the item does not have any kind of unqualified phenomena, such as short circuits, open circuits, etc.

The PCBA test rack is devoted to Particular boards. It is composed of the test point setting and various external instruments, user interfaces, and accessory circuit boards according to the size of the PCB board generated. It is mostly made use of to find the connection of the circuit card to make certain that the item does not have any type of malfunctioning sensations, such as short circuits, open circuits, and so on. Some touch pins and wires are connected to form an easy examination shelf.

The top quality of the test shelf in PCBA processing is connected to the performance and pass rate of product testing. The examination will be operated for a very long time, so when making the test shelf, you have to choose top quality to fulfill manufacturing requirements.

The PCBA examination shelf is a crucial detection tool in SMT manufacturing. It can mainly check the created circuit card and determine whether the board is a good product with the spotted signal pictures and seem temperature level.
