How long can we keep PCBA printed circuit board

PCBA printed circuit board after processing is completed, due to the choice of materials, processing technology, the different environments, there will be different shelf life, usually 2-10 years.

  1, the impact of materials

Different substrate materials and different quality components have a great influence on the shelf life of PCBA. The higher the quality of PCB boards and components, the stronger the reliability, and the stronger the ability to withstand harsh environments and the ability to resist oxidation. The longer the retention period will be.

  2, the impact of the process

Different processing technologies, such as PCBA printed circuit board coated with three anti-paints, have a longer shelf life than PCBA printed circuit boards without anti-painting.

  3, the impact of the environment

If the PCBA printed circuit board is in a humid, dusty, high temperature and high pressure environment for a long period of time, it must have a long shelf life in a dry, dust-free environment.
