PCBA Aging Test is the process of evaluating and verifying the reliability of PCBAs under prolonged use and environmental changes. It aims to simulate the aging of PCBA in actual use to determine whether it can maintain stable and reliable performance in long-term operation.
Designing the aging test programme: According to the design specifications of the PCBA and the environment in which it is to be used, determine the parameters and conditions of the aging test, including aging time, temperature, humidity, voltage, etc. Relevant industry standards or empirical data can be referenced for design.
Set up aging test equipment: Prepare equipment suitable for the aging test, such as aging box, constant temperature and humidity box, power supply regulator, etc. Set the parameters of the equipment, such as temperature, humidity, voltage, according to the test programme.
Place the PCBA in the aging test equipment: Ensure the PCBA is placed in the aging test equipment and securely connected to it. Expose the PCBA to the corresponding environment according to the conditions set in the test programme.
Run the aging test: Run the aging test according to the time set in the test programme. Monitor the PCBA’s electrical parameters and performance changes, such as voltage, current, frequency, resistance, etc. Real-time monitoring or regular sampling with test equipment can be done.
Verify aging test results: After completing the aging test, conduct functional and performance tests on the PCBA to verify its reliability and stability under aging conditions. This may involve verifying functional modules, communication interfaces, input and output ports, etc.
Record and report: Record the results of the aging test and create the corresponding test report. This helps with quality control, traceability, as well as subsequent product maintenance and improvement.
PCBA aging test is crucial to ensure the stability and reliability of PCBA in long-term use. It helps in identifying potential aging issues and implementing timely repairs and improvements.
