Question: Do you know how long pcba products can be stored?

We call the board of various components welded on the surface of the printed circuit board PCBA, with the development of science and technology, people have begun to pay more and more attention to the use time of the PCBA circuit board and the reliability of high frequency operation, and then PCBA is also paying more and more attention to its storage life. Under normal circumstances, the storage time limit of PCBA is 2 to 10 years, and today we will talk about the influencing factors of the storage cycle of PCBA finished boards.

Factors affecting the storage cycle of PCBA finished board

01 Environment

The wet and dusty environment is obviously not conducive to the preservation of PCBA. These factors will accelerate the oxidation and fouling of PCBA and shorten the shelf life of PCBA. In general, it is recommended to store PCBA in a dry, dust-free, constant temperature of 25 ° C.

2 Reliability of components

The reliability of components on different PCBA also largely determines the storage life of PCBA, the use of high-quality materials and processes of components have the ability to resist harsh environments, its ability to range wider, stronger oxidation resistance, which also provides a guarantee for the stability of PCBA.

3. Material and surface treatment process of printed circuit board

The printed circuit board material itself is not easily 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 running load

The workload of a PCBA is the most important factor in its lifetime. High frequency and high load operation will have continuous high impact on the circuit board lines and components, and it is easier to oxidize under the influence of heating, resulting in short circuit and open circuit during long-term operation. Therefore, the working parameters of the PCBA board should be in the middle range of the component to avoid approaching the peak value, so as to effectively protect the PCBA and extend its storage life.
