Circuit board storage method

The circuit board is the provider of the electrical connection of various electronic components, and its function cannot be ignored. It needs to be stored after the pcb circuit board is completed, so as to avoid certain damage of the circuit board.


1. The circuit board needs to be vacuum-packed with a colorless odor plastic bag, and the desiccant should be attached to the vacuum bag to ensure that there is no air leakage in the package. Can not be in contact with air and water, to avoid the surface of the PCB circuit board immersion gold, spray tin and the part of the pad is affected by oxidation, which is not conducive to production.


2. The edge of the circuit board packaging box needs to be wrapped with a bubble film. The water absorption of the bubble film will be better, which can play a moisture-proof effect, and it is also indispensable in the moisture-proof beads.


3. The circuit board should be labeled and classified. After sealing, the box must be separated from the wall and stored in a dry and ventilated place and in a place where there is no direct sunlight.


4. When the circuit board is stored, the warehouse temperature is preferably controlled at 23±3°C, 55±10% RH. Under such conditions, the surface treated pcb circuit boards such as immersion gold, electric gold, spray tin, and silver plating are generally available. After storage for 6 months, the surface treated pcb circuit boards such as Shenyin, Shenxi, OSP can be stored for 3 months.


5, if you do not use the circuit board for a long time, it is best to brush a layer of three anti-paint, three anti-paint can make the circuit board moisture-proof, dust-proof, anti-oxidation. The storage life of such pcb boards will be extended to 9 months.


The above is the professional storage board storage method. Although the pcb circuit board has a good reputation in the industry, its quality and processing quality are also very high, but if you do not do the storage work of the pcb circuit board, then It will also affect the use of the pcb board and also affect its service life.
