The retention times of PCBA is related to the storage environment and it is suggested to store it in a dry, clean, dust-free environment. The humidity and dust content of the storage environment will have an impact on the PCBA. The reliability and antioxidant capacity of electronic parts on PCBA board is stronger, the longer the storage time. Meanwhile, PCBA plate and production process is also important factor affecting the storage time of PCBA.
PCBA preservation period is a comprehensive work, to follow the scientific design specifications ,production process specifications and operating standards, which can extend the maximum shelf life.
