1. PCB boards need to be vacuum packed in colourless air bead plastic bags, the bags should be accompanied by the necessary desiccant to ensure that the bags are packed tightly. Can not be in contact with wet air, so as not to be affected by the PCB surface spray tin, accumulation of gold and pad oxidation, to the detriment of production.

1. PCB boards need to be vacuum packed in colourless air bead plastic bags, the bags should be accompanied by the necessary desiccant to ensure that the bags are packed tightly. Can not be in contact with wet air, so as not to be affected by the PCB surface spray tin, accumulation of gold and pad oxidation, to the detriment of production.
2. When packaging printed circuit boards, you need to wrap a layer of bubble film around the box, bubble film is absorbent and can absorb water to prevent moisture. In addition, the packaging can be placed in the moisture-proof beads.
3. Place the PCBs in categories and label them. Once sealed, the box must be kept away from walls and floors. Store the boxes in a dry and ventilated place, out of direct sunlight.
4. PCBs should be stored at a controlled temperature of 233 and 5510% relative humidity. Under these conditions, printed boards with surface treatments such as gold plated, electro-gold sprayed, silver plated can generally be stored for 6 months, and printed boards with surface treatments such as sunken silver, sunken tin, OSP can generally be stored for 3 months.
5. For long-term use of the PCB, it is best to brush a layer of three-proof paint on it, can be moisture-proof, dust-proof, anti-oxidation. In this way, the storage life of the PCB will increase to 9 months.
Several methods of encapsulating printed circuit boards are described here. In fact, the storage time of PCBs is related to the surface treatment. Gold plating and electroplating is the longest and can be stored for two or three years at constant temperature and humidity. Good PCB storage can extend the service life of PCBs, which is a problem that should not be ignored. Yaxinda Electronics will also do its best to ensure the quality of delivery.
