PCBA reliability testing methods, there are many testing methods, and the following are several common testing methods:

1. Temperature cycling test: This test is mainly aimed at testing the performance of PCBA at different temperatures. Place the PCBA at three different temperatures, high, medium, and low, for cyclic testing to evaluate its stability at different temperatures.

2. Humidity test: This test is mainly aimed at testing the performance of PCBA in different humidity environments. Test PCBA in different humidity environments to evaluate its stability.

3. Vibration testing: This test is mainly aimed at testing the performance of PCBA in different vibration environments. By simulating the vibration environment in actual use, vibration testing is conducted on PCBA to evaluate its stability in different vibration environments.

4. Electrical performance testing: This test is mainly to check whether the electrical performance parameters of PCBA meet the design requirements. Evaluate whether PCBA meets design requirements by testing its electrical performance parameters such as voltage, current, resistance, capacitance, etc.

5. Lifetime testing: This test is mainly aimed at evaluating the service life of PCBA. Evaluate the service life of PCBA by running it for a long time and observing its performance.
