What are the PCBA storage conditions and requirements?

After completing the final processing of PCBA, if the finished product assembly is not carried out in time, PCBA needs to be stored to prevent PCBA from exposing the air for a long time and affecting the performance of PCBA.

PCBA storage conditions are mainly:

1. Apply three anti -paint

For a long -term non -instrumental PCBA board, three -proof paint should be applied, which has the functions of moisture -proof, dustproof, and oxidation. It can effectively extend the storage time. After applying the three -month -proof paint, it can be extended for 9 months.

2. Vacuum packaging method

PCBA storage cannot be in contact with air and water. First of all, the PCBA board is packaged with a vacuum bag, and it needs to be surrounded by a layer of air bubble film on the side of the box. The water absorption of the bubble film is better. Less. Then classify and emit the label. After the box is sealed, the box must be partitioned and placed in a dry and ventilated place, and the sun should be avoided.

3. Control the temperature and humidity of the warehouse

The temperature of the warehouse saved by PCBA is best controlled at 23 ± 3 ° C, 55 ± 10%RH, the temperature with good storage conditions is less than 25 degrees, the relative humidity is less than 65%, with temperature control, and the indoor environment has no corrosive gas.

For the OSP process PCB, due to its thin protective membrane, PCBA needs to be stricter during storage.
