How to store PCBs? | Fast turn PCB

When PCBs are shipped in vacuum packaging through final product inspection, for bulk PCBs, the typical PCB manufacturer will make more inventory or prepare more spare parts for the customer. Once each order is ready, the vacuum packaging will be stored. Waiting for shipment. So why vacuum pack PCB boards? How are they stored after vacuum packing? How long is the shelf life? The following will give you a brief overview.

How to store and shelf life of PCBs:

Why vacuum pack PCBs? PCB factories take this very seriously. Because PCBs are not sealed, the gold, tin and solder surfaces can oxidize and interfere with soldering, which is detrimental to production.

So, how to store the PCB?The board is only other products and should not come into contact with air and water. First of all, the vacuum of the PCB board must not be broken. When packing, it is necessary to seal bubble wrap on the side of the box. The bubble film has better water absorption and plays a very good role in preventing moisture. Of course, moisture-proof beads are also essential. Then sort and discharge the labels. After sealing, the boxes must be stored in a dry and ventilated place, isolated from the ground, and should be protected from direct sunlight.

For PCBs that will not be used for a long period of time, the board manufacturer should apply a layer of tribo varnish, which protects against humidity, dust and oxidation. This will extend the shelf life of the PCB for up to 9 months.
