PCBA finished board preservation cycle
PCBA is a printed circuit board with various components soldered on the surface. Many people pay attention to the reliability of its long-term, high-frequency operation, and occasionally need to understand its shelf life. Under normal circumstances, the shelf life of PCBA is 2~10 years, which is mainly affected by the following factors:

1. The environment

A humid and dusty environment is obviously not conducive to the preservation of PCBA. These factors will accelerate the oxidation and dirt of PCBA and shorten the shelf life of PCBA. In general, it is recommended to store PCBA in a dry, dust-free space with a constant temperature of 25 degrees Celsius.

2. Reliability of components

The reliability of components on different PCBAs also largely determines the shelf life of PCBA. Components with high-quality materials and processes have the ability to withstand harsh environments, with a wider range of capabilities and stronger oxidation resistance, which is also PCBA Stability is guaranteed.

3. Material and surface treatment process of printed circuit board

The material of the printed circuit board itself is extremely unlikely to be affected by the environment, but its surface treatment process is greatly affected by air oxidation. Good surface treatment can extend the shelf life of PCBA.

4. PCBA board operating load
PCBA operating load is the most important factor in its shelf life. The operation of high frequency and high load will cause continuous and high impact on the circuit and components of the circuit board. Short circuit, open circuit phenomenon appears. Therefore, the operating parameters of the PCBA board should preferably be in the middle value range of the components and avoid near the peak value. This can effectively protect the PCBA and extend its shelf life.
The preservation period of PCBA is a comprehensive work, which needs to follow scientific design specifications, production process specifications and operation specifications, so that the preservation period can be extended to the greatest extent. iPCB is happy to be your business partner.
