All printed circuit boards are 100% electrical tested. Electrical testing mainly includes flying probe testing and electronic fixture testing. Flying probe test is used for samples or small batch orders due to its flexibility, but its efficiency is relatively low. Electronic fixture testing is suitable for large-volume orders or repeated orders. There is an automatic picker here. According to the test results, the PCB is automatically classified and sent to the electronic fixture testing machine, and the PCB is placed in the designated position after the test.
