PCBA aging test method
In the PCBA processing process, we often find that the various functional indicators of the PCBA PCBA manufacturing board are normal during the shipment process, but after a period of use, the customer finds that there will be many bad conditions and proposes to return to the factory for repair, then after the investigation by the technicians, After searching for the reason and other operations, you will find that the PCBA may have been aging and cannot operate normally and quickly. Therefore, it is very necessary to conduct aging tests on PCBA processed products.
PCBA aging test method:
1. Put the PCBA board at ambient temperature into the thermal aging equipment at the same temperature, and the PCBA board runs.
2. Reduce the temperature in the equipment to a specified temperature value at a specified rate. When the temperature in the equipment reaches a stable level, the PCBA board should be exposed to low temperature for two hours.
3. Raise the temperature in the equipment to the specified temperature at a specified rate. When the temperature in the device reaches a stable level, the PCBA board should be exposed to high temperature for 2h.
4. Reduce the temperature in the equipment to room temperature at the specified rate, repeat continuously until the specified aging time, and measure and record the PCBA board according to the specified aging time.
This is the specific steps of the PCBA led pcb burn-in test method. These steps should have been carried out before leaving the factory. Jie Duobang treats customers with integrity for many years, and every step of the business will naturally carry out a complete burn-in test. The perfect circuit board is delivered to the customer!
