Reliability Tests For PCBA Processing

PCBA manufacturing is the process of combining material procurement with SMT chip processing. Any problem with any material used can affect the overall quality of the PCBA board. Therefore, we need to have sufficient material inspection capabilities, supplier management ability, technical analysis ability, and reliability testing ability.

Reliability testing is an essential part of the PCBA processing process, but it is often ignored by manufacturers. They assume that as long as the PCBA board passes the functional test, it will be accepted by the end customer. However, many PCBA boards have fatal defects such as short service life and unstable performance in terminal products, which are caused by the PCBA factory's failure to strictly implement reliability tests.

Reliability Tests For PCBA Processing

To carry out the reliability test of the PCBA board, we can use the following methods:

1. Aging Test: This involves placing the PCBA board under specific temperature and humidity conditions and performing repeated power on and off, simulation function operation, load operation, etc. The stability of the PCBA board is then checked through 24 to 72 hours of continuous work. Although the aging test takes a long time, it is necessary to ensure that the batch of products is reliable. In the actual process, the aging test is only a sample test, and the overall yield of this batch of products is judged by the qualified rate of the random test.

2. Vibration Test: During transportation, many PCBA boards can be damaged due to vibration. Therefore, it is essential to simulate the vibration effect during transportation in the laboratory and expose hidden defects in the welding process. This way, batch welding defects can be avoided to the greatest extent, and the overall yield rate of delivery is improved. You can purchase professional analog motion vibration workbenches on the market for around 5,000 yuan.

3. Surge Impact Test: This test involves checking the PCBA board for defects that may occur due to occasional surges in voltage. Many circuit designs are not perfect and often fail to consider the impact of instantaneous voltage or current on the entire circuit. Therefore, it is necessary to conduct sampling surge impact experiments before the mass production of PCBA.

4. Packaging Test: This test simulates the packaging form of the PCBA board and ensures that it can withstand the impact of transportation. The factory shall conduct proper drop tests to avoid any damage during transportation.

The reliability experiment of the PCBA board is not limited to the above methods. Each PCBA factory can negotiate with customers to determine specific reliability test plans based on actual conditions, to pursue higher-quality manufacturing.
