What Are The Conditions And Requirements For PCBA Storage？

Publish Time: January 05,2019

We all know that in the process of PCBA production, the requirements for the production environment are very high, but the requirements for the storage of PCBA boards are also very high. Because after PCBA processing is completed, if the product is not assembled in time, then PCBA needs to be stored to prevent PCBA from being exposed to the air for a long time and affecting the performance of PCBA.

Let me introduce the main conditions of PCBA storage:

1,Apply three anti - paint

For PCBA boards that have not been used for a long time, three anti-paints should be coated, which has the effects of moisture, dust, and oxidation resistance, which can effectively extend the storage time of PCBA.

2,Vacuum packaging

PCBA storage is not in contact with air and water. First, use a vacuum bag to package the PCBA board, and a bubble film needs to be wrapped around the box when packing. The water absorption of the bubble film is better, which plays a good role in moisture resistance. Of course, the moisture-proof beads cannot Less. Then affix labels to the classified emissions. After sealing, the box must be stored in a dry and ventilated place across the wall and off the ground, and it should be protected from sunlight.

3,Control the temperature and humidity of the warehouse

When PCBA is stored in the warehouse, the temperature of the warehouse should be controlled at 23 ± 3 ℃, 55 ± 10% RH. The storage conditions should be less than 25 ° C, relative humidity less than 65%, with temperature control, and no corrosive indoor environment gas.
