One, besmear three prevent lacquer
For the PCBA board which is not used for a long time, it should be coated with a three-proof paint, which has the functions of moisture-proof, dustproof and anti-oxidation, and can effectively extend the storage time. After being coated with a three-proof paint, it can be extended for 9 months.
Ii. Vacuum packing method
PCBA storage is not in contact with air and water. First of all, the PCBA board should be packed with vacuum bags, and a layer of bubble film should be placed around the side of the box during packing. Bubble film has good water absorption, which plays a very good role in preventing moisture. Of course, moisture-proof beads are also indispensable. Then sort them and put them on the label. After sealing, the boxes must be kept in a dry and ventilated place away from the ground and away from sunlight.
