- The printed circuit board of the print must be vacuum packed with a colorless gas ballet plastic bag and the desiccant must be attached to the vacuum bag to ensure tight packaging. Cannot come into contact with air and water to avoid the surface of the circuit board. Immersion gold, aerosol and paddles are oxidized and influence welding, is not conducive to production.
- For PCB PCBs that are not used for a long time, it is best to apply a coat of three anti-paints. The effect of the three anti-paints can prevent moisture, dust and oxidation. This extends the shelf life of the printed circuit board to 9 months.
3. Rapid PCB prototyping in Illinois packaging requires a layer of bubble film on the edge of the box, the water absorption of the bubble film is better so that it can play a role in water absorption and moisture. In addition, moisture-resistant beads cannot be less.
4. the PCB circuit board labeled according to the classification of emissions. After sealing, the box must be distributed, stored in a dry and ventilated place away from the ground, but also to prevent sunlight.
5. The storage temperature of the PCB circuit board is preferably controlled at 23 ± 3 ° C and 55 ± 10% RH. Under such conditions, surface treated circuit board plates such as gold, electric gold, spray tin and silvering can generally be stored. Surface treated PCBs such as Shenyin, Shenxi and OSP can generally be stored for 3 months for 6 months.
In fact, the PCB circuit board is stored for a long time. It is related to the surface treatment. The gold and galvanic gold are the longest in rapid PCB prototyping in Illinois. They can be stored for two or three years under constant temperature and humidity conditions. Doing well PCB PCB storage to better extend the life of the PCB cannot be ignored.
