When packing the PCB board on both sides, a bubble film should be put around the edge of the box, and the water absorption of the bubble membrane is better, so it can absorb water and prevent moisture. In addition, moisture-proof beads are also necessary.

PCB Knowledge:

The double sided PCB board needs to be packed in a colorless plastic bag in vacuum, and the bag should be packed with desiccant and keep packing tight. It should not contact with air and water to avoid the surface deposition of PCB circuit board, tin spray and pad oxidation will affect the welding, which is not good to production.

When packing the PCB board on both sides, a bubble film should be put around the edge of the box, and the water absorption of the bubble membrane is better, so it can absorb water and prevent moisture. In addition, moisture-proof beads are also necessary.

It should label double sided PCB board according to classification. After the box must be partitioned, stored off the ground in dry ventilation, and at the same time avoid sunlight.

Warehouse temperature of PCB storage is best controlled at 23 ±3 ℃, 55 ±10RH. Under such conditions, the PCB with surface treatment such as Immersion gold, electric gold, HASL and silver plating can generally be stored for 6 months. Surface treated PCB boards such as OSP and Immersion silver can generally be stored for 3 months.

For long time unused PCB circuit board, it is best to brush a layer of conformal coating. The conformal coatings can prevent moisture, dust and oxidation. In this way, the storage life of the PCB circuit board will be increased to 9 months.( pcb products)

FAQ:

1. How to Get a quotation?

For PCBs,pls send us the Gerber File.For PCBA,pls send us the Gerber file and BOM(Bill of Materials)

2. What is the MOQ?

No MOQ.1 pcs is ok.

3.What is the lead time?

For PCB orders,the lead time is 2 to 10 days.For PCBA orders,the lead time will be 15 to 30 days.

4.Will the boards be tested before shippment?

Yes,all PCBs will be tested by Flying Probe or E-test.For PCBA,we will have AOI,X-ray,and functional test
