AI Technical Summary
Technical Problem
Existing PCBA test fixtures require multiple manual adjustments to align the PCBA board with the groove, resulting in low testing efficiency.
Method used
A high-precision PCBA test fixture including an auxiliary device and a material ejection device was designed. The auxiliary device helps the PCBA board to quickly align with the lower fixture surface through components such as hydraulic rods, sliders, rotating wheels and scale plates. The material ejection device conveniently removes the PCBA board through a multi-section rod and push block structure.
Benefits of technology
It improves the placement efficiency and integrity of PCBA boards, reduces multiple adjustment steps, and ensures the accuracy of testing and work efficiency.
