The PCB and PCBA Test Rack: Principles and Applications

There are two types of test racks that are used in the PCBA manufacturing process. One is the PCB Test Rack and the
other is the PCBA Test rack. Many consumers confuse the two types of test shelves,
while others don’t know their purpose. Let Orinew Technology explain the uses and principles of these two test
shelves.

PCB Test Racks can be customized to meet customer requirements. They are determined by
the size of the board and the location of solder joints. Generally, it is made up of epoxy panels, metal
wires and probes, as well as detection interfaces. It is mainly used to check the continuity of a
circuit card in order to ensure that there are no unqualified sensations such as open circuits or short
circuits.

PCBA Test Racks are dedicated to particular boards. The PCB test rack is composed of
different external tools and interfaces as well as accessory motherboards according to the size of the
generated PCB board. The main purpose of this tool is to check the motherboard continuity to make sure
that there are no defects such as open circuits or short circuits. A few touch pins and cable are
connected together to create an easy inspection rack.

PCBA inspection racks are a vital tool for SMT production. The PCBA examination rack can be used to
evaluate the circuit board and determine whether it is a good product by evaluating the signal images
and temperature.

The effectiveness of item screening and the pass rate are directly related to the quality of the test
shelf. You will run the test for a long time so you should choose high-quality materials to meet
manufacturing requirements.
