In the quotation of batch PCBA processing, the cost of the test fixture usually appears, and many customers don't understand the specific function of the test fixture. Next, the PCBA OEM Shenzhen BQC will introduce the PCBA test fixture and its use.
一. What is test fixture?
The principle of PCBA test fixture is very simple. It is to connect the pads or test points on the PCB with metal probes, and obtain typical values such as voltage value and current value of the test circuit when the PCB is powered on, so as to observe whether the tested circuit is on normally.
The production of PCBA test fixture is customized, which is determined according to the size of PCB to be tested, the position of test points and the value to be tested. Acrylic, plastic, metal probes, display screen, wires and a simple PCB circuit board are mainly used to complete the whole production.
二. The purpose of PCBA test fixture
PCBA test fixture is widely used in the whole PCBA manufacturing process, which is mainly used to test the PCBA board after SMT patch and DIP plug-in, especially ICT test, that is, to test the electrical conductivity of the circuit board through test points, so as to determine whether the whole PCB board is soldered successfully. The PCBA test fixture is the main tool used to assist in this test.
