AI Technical Summary
In the testing of LED semi-finished product brackets, the existing electrical testing probes are prone to bridging adjacent pins or conductive layers due to their wide contact surface, resulting in false conduction signals. Furthermore, dust interferes with the identification of weak electrical differences, affecting the accuracy of the test.
Design an electrical detection probe with a detection section width smaller than the mating section and an inclination angle of 60° to 80°. The mating section has an inclination angle of 20° to 40°. The probe is made of a material with excellent compressive strength and conductivity to avoid dust accumulation. It is combined with an ion air knife to remove static electricity and dust.
It improves the accuracy and sensitivity of electrical detection, avoids dust interference, and ensures the stability and reliability of the detection function.
