Cum se depozitează placa PCB?
The circuit board is no different from other products, it cannot come into contact with air and water. First, the vacuum of the PCB board cannot be damaged. Wrap a layer of bubble wrap around the side of the box when packing. The bubble film has good water absorption and plays a very good moisture-proof effect. Of course, moisture-proof beads are also indispensable. Then sort them and label them. After sealing, the box must be separated from the wall, stored in a dry and ventilated place away from the ground, and protected from sunlight. The temperature of the warehouse is best controlled at 23±3 degree , 55±10 percent RH. Under such conditions, PCB boards with surface treatments such as immersion gold, electro-gold, tin spraying, and silver plating can generally be stored for 6 months. PCB boards with surface treatment such as tin immersion and OSP can generally be stored for 3 months.
Pentru plăcile PCB care nu vor fi folosite mult timp, cel mai bine este ca producătorul plăcii de circuite să picteze un strat de vopsea conformă pe el. Rolul vopselei cu trei-rezistențe este rezistentă la-umiditate, la-praf și la-oxidare. Ca urmare, durata de viață a plăcii PCB va crește la 9 luni.
