The working principle of PCBA testing fixture

PCBA testing fixture is an important equipment of PCBA assembly process, usually placed on the end of the production process. PCBA testing fixture mainly through test probe to contact test point on the pcb prototype, PCBA assembly board circuit to obtain the key data, such as current, voltage and input and output detection circuit open circuit, short circuit and the features of the product can run normally. Electronic product design engineers in PCB design, will set aside a special test points, and prepare the test plan, test for manufacturers.
