[0002] In the 3C industry, with the increasing degree of electronicization, the demand for PCBA is huge. PCBA needs to be burned with software and tested for performance indicators after SMT placement. First, the software program needs to be burned into the PCBA to realize the PCBA driving function; when burning, a burning fixture is needed to assist in burning the program into the PCBA. The PCBA needs to be installed on the burning fixture, and then the probe of the burning fixture is pressed on the PCBA for burning, and then the burned PCBA is tested.
