1. Good storage environment: temperature is less than 25 degrees, relative humidity is less than 65%, with temperature control, no corrosive gas in the indoor environment.
2. General storage conditions: the temperature is not higher than 35 degrees, the relative humidity is less than 75%, and the indoor environment is free of corrosive gas.
3. The temperature of the PCBA warehouse should be controlled at 23±3℃, 55±10%RH. Under such conditions, PCBA boards with surface finish such as immersion gold, electro-gold, HASL, and immersion silver plating can generally be stored for six months. PCBA boards with surface treatments such as immersion silver, immersion tin, OSP, etc., can generally be stored for three months.
The storage period of PCBA is a comprehensive work, which needs to follow scientific design specifications, production process specifications, and operation specifications so that its storage period can be extended to the greatest extent.
