About PCBA finished board storage

(Summary description)We know that PCBA is a printed circuit board with various components soldered on the surface. Many people generally only pay attention to the reliability of its high-frequency operation time, but have little understanding of the storage period. Sanjing will introduce to you by the way. In general, the storage period of PCBA is 2~10 years.
However, the storage of PCBA finished boards is easily affected by many factors, such as storage environment, component reliability, printed circuit board material and surface treatment process, operating load, etc. The following Sanjing will introduce you in turn:
The first one is the storage environment. For example, it is not conducive to storing PCBA in a humid or dusty environment, because these factors are easy to accelerate the oxidation of PCBA, make the PCBA board surface dirty, and shorten the shelf life of PCBA. Therefore, under normal...

Information

We know that PCBA is a printed circuit board with various components soldered on the surface. Many people generally only pay attention to the reliability of its high-frequency operation time, but have little understanding of the storage period. Sanjing will introduce to you by the way. In general, the storage period of PCBA is 2~10 years.

 

However, the storage of PCBA finished boards is easily affected by many factors, such as storage environment, component reliability, printed circuit board material and surface treatment process, operating load, etc. The following Sanjing will introduce you in turn:

 

The first one is the storage environment. For example, it is not conducive to storing PCBA in a humid or dusty environment, because these factors are easy to accelerate the oxidation of PCBA, make the PCBA board surface dirty, and shorten the shelf life of PCBA. Therefore, under normal circumstances, it is recommended to store PCBA at a constant temperature of 25°C and a dry and dust-free environment.

 

 

Secondly, component reliability. Generally speaking, the reliability of the components on the PCBA board determines the storage period of the PCBA to a certain extent, and the quality of the components is also an important factor in determining the reliability of the components. The components of high-quality materials and processes have the ability to resist harsh environments, such as strong oxidation resistance, so that the stability of the PCBA is more secure.

 

Printed circuit board material and surface treatment process. The material of the printed circuit board itself is not easily affected by the environment, but its surface treatment process is easily affected by air oxidation. Good surface treatment technology can extend the shelf life of PCBA.

 

The last one is the PCBA operating load. In addition to some of the influencing factors we mentioned above, PCBA operating load is also a more important influencing factor. High-frequency and high-load operation will have a continuous high impact on the circuit board and components, and the circuit board is more likely to be oxidized when heated, which will easily lead to short circuits and open circuits during subsequent operation. Therefore, it is best to set the operating parameters of the PCBA board in the middle value range of the components and avoid near the peak value. This will not only protect the circuit board, but also extend the PCBA storage period.

 

To sum up, PCBA storage is not a single job, and it needs to start from multiple aspects at the same time to maximize the storage period. For PCBA boards that have not been used for a long time, a layer of three-proof paint can be sprayed on the surface of the board, which can prevent moisture, dust, and oxidation, thereby prolonging the storage period of PCBA.

 

The above is an introduction to the relevant content of PCBA finished board storage, I hope it can be helpful to everyone!
