PCBA aging test

In order to ensure the stability and reliability of PCBA products, it is best to carry out an aging test after PCBA processing is completed. The main purpose of aging test is to simulate the daily use environment of the product through the comprehensive action of high temperature, low temperature, high and low temperature change and electric power, and to expose the defects of PCBA, such as poor soldering, mismatch of component parameters, and faults caused in the debugging process, so as to eliminate and improve.

There are three standards for PCBA aging test. According to these three standards, general problems can be found.

1. Low temperature operation: after placing the PCBA board at-10 ±3 ℃ for 1 hour, under this condition, with rated load, 187V and 253V,electrify running all programs, the program should be correct.

2. High temperature operation: after placing the PCBA board at 80±3°C for 1 hour, under this condition, with rated load, 187V and 253V, electrify running all programs, the program should be correct.

3. High temperature and high humidity operation: the PCBA board in the temperature of 65 ± 3 °C, humidity 90-95% conditions, time 48h, with rated load, electrify running all programs, the program should be correct.

The specific practices of the PCBA aging test are:

1. Place the PCBA board at ambient temperature into the heat aging equipment at the same temperature, and the PCBA board is in operation.

2. Reduce the temperature inside the equipment to the specified temperature at a specified rate. After the temperature in the equipment has stabilized, the PCBA board should be exposed to low temperature for 2 h.

3. Increase the temperature inside the equipment to the specified temperature at a specified rate. After the temperature in the equipment has stabilized, the PCBA board should be exposed to high temperature for 2 h.

4. Reduce the temperature inside the equipment to room temperature at a specified rate, repeat until the specified aging time, and measure and record the PCBA board according to the specified aging time.
