Principle and Application of PCB and PCBA Test Rack

Two types of test racks are commonly used for the PCBA production process, one is the PCB test rack,
and the various other is the PCBA test rack. Some consumers usually confuse these 2 types, and some
clients do not know what these test shelfs are used for. Allow High-Quality PCB present the principles
and uses of these two examination shelfs.

PCB test racks are customized according to customer needs and are figured out by the dimension of the PCB board to be generated and the location of the solder joints. It is generally composed of epoxy
material panels, metal probes, wires, and detection interfaces. It is mostly used to detect the
continuity of the circuit card to guarantee that the product does not have any unqualified sensations,
such as short circuits, open circuits, etc.

The PCBA test rack is devoted to Particular boards. It is made up of the test point setting and
different external tools, user interfaces, and accessory motherboard according to the dimension of the
PCB board generated. It is primarily utilized to discover the continuity of the motherboard to ensure
that the product does not have any type of defective sensations, such as short circuits, open circuits,
and so on. Some touch pins and cables are connected to form an easy examination rack.

The PCBA examination rack is an indispensable discovery tool in SMT manufacturing. It can mostly
evaluate the produced circuit card and figure out whether the board is an excellent product via the
spotted signal pictures and appear temperature.

The top quality of the examination shelf in PCBA handling is related to the effectiveness and pass price
of item screening. The test will be run for a very long time, so when making the test shelf, you need to
pick high quality to fulfill manufacturing needs.
