For China pcb manufacturer, PCBA storage conditions and requirements


After the final processing of PCBA,for China pcb manufacturer, PCBA needs to be stored if it is not assembled in time to prevent PCBA from being exposed to the air for a long time which will affectthe performance of PCBA.




For China pcb manufacturer, PCBA storage conditions are mainlyas below:


1.Coatingthree anti-paint

For long-term non-use PCBA board, it should be coated with three anti-paint, which has the functions of moisture-proof, dust-proof and anti-oxidation, which can effectively extend the storage time and extend for 9 monthsafter applying three anti-paints


2.Vacuum packagingway

For China pcb manufacturer, PCBA storage can not in contact with air and water. Firstly, the PCBA board is packaged in a vacuum bag, and a bubble film is required to be placed on the side of the box when the box is packed. The water absorption of the bubble film is relatively good, which plays a good role in moisture prevention. Of course, the moisture-proof beads is necessary . Then sort and attachthe label. After sealing, the box must be stored in a dry and ventilated place, separated from the ground, and should be protected from sunlight.


3.Controlling the temperature and humidity of the warehouse

For China pcb manufacturer, the temperature of the warehouse where PCBA is stored is preferably controlled at 23±3°C, 55±10%RH, the storage temperature is less than 25 degrees, the relative humidity is less than 65%, temperature control, and the indoor environment is free of corrosive gases.


For China pcb manufacturer, the OSP craft PCB, due to its thin protective film, PCBA requires more stringent storage conditions.
