Application of test probes in electronic testing
The types of test probes include PCB probes, ICT function test probes (automotive wiring harness test probes, battery needles, current and voltage needles, switch needles, capacitor polarity needles, high frequency needles), BGA test probes, etc.
According to different origins, it is divided into American QA probe, American ECT probe, American IDI probe, etc., German INGUN probe, German PTR probe, etc., Korean LEENON probe, Taiwan CCP China probe, Taiwan UC Youchuan probe Wait.
The probe is the contact medium for electrical testing, and it is an excellent precision electronic hardware component.
Test pin, a probe used to test PCBA.
The surface is gold-plated, and there are high-performance springs with an average life span of 30,000 to 100,000 times inside.
At present, the more famous foreign manufacturers are: ECT, INGUN, QA, IDI, Semiprobe
Material of probe: W, ReW, A+
1. At present, the main materials used are W, ReW, which are generally elastic, easy to shift, stick to gold chips, need multiple cleanings, long wear and tear, and average life.
2. The clean-free needle made of A+ material has good elasticity, is not easy to shift during the test, and does not stick to gold chips and is free of cleaning, so it has a longer life.
