What Is The PCBA Test Jig In PCB Assembly?

Time:2020-09-15 21:18:58 Click:

In the Quotation of mass PCB Assembly , the cost of PCBA Test Jig usually appears. A great number of customers do not understand what it is. Now, Grande would like to introduce what PCBA Test Jig is as well as its function.





What is the PCBA Test Jig?


The principle of the PCBA Test Jig is quite simple: It connects the pads or test points on the PCB board through metal probes. When the PCB board powers on, the voltage value, current value and other typical values of the test circuit will be acquired, which is the basis to learn whether the circuit conducts normally or not.


PCBA Test Jigs are all customized, which is determined according to the size of those to be tested PCBs , the location of the test point and the value to be tested, and which mainly use acrylic, plastic, metal probe, display screen, wire and simple PCB circuit board to complete the whole production.





What is the function of PCBA Test Jig?


The PCBA Test Jig is widely used in the whole PCB Assembly process. It is mainly used to test the circuit board after the SMT and DIP Process. Among them, the ICT test is mainly used, that is, the electrical conduction of PCBA is tested through the test point, which is the method to determine whether the entire PCBA board is successfully soldered or not. The PCBA Test Jig is one of the main tools that used to assist in this test.

In addition, due to the quality of PCBA Test Jig is related to the efficiency and straight-through rate of ICT testing. Adding its long-term frequent operation, which lead to high requirements for its production quality. Therefor, every single PCBA manufacturers should pay more attention to.
