PCB packaging 

1. The PCB circuit board needs to be vacuum packed with colorless gas bead plastic

bags, and the bags should be attached with necessary desiccant and ensure that the bags

are tightly packed.Can not contact with wet air, avoid PCB circuit board surface spray

tin, gold deposition and welding pad parts are oxidized and affect the welding, is not

conducive to production.
2. When packing the PCB circuit board, it is necessary to

surround the box with a layer of bubble film. Because the bubble film has good water

absorption, it can absorb water and moistureproof.In addition, moisture-proof beads can

be placed in the case.
3, put the PCB circuit board classification, label.After sealing,

the box must be kept away from the wall and the floor.Store in a dry, ventilated place

and avoid direct sunlight.
4, the warehouse temperature of PCB circuit board storage is

best controlled at 23±3℃, 55±10%RH, under such conditions, gold, gold, tin spraying,

silver plating PCB circuit board surface treatment can generally be stored for 6

months, silver, tin, OSP surface treatment PCB circuit board can be stored for 3

months.
5, for a long time do not use the PCB circuit board, it is best to brush a layer

of three anti paint, three anti paint can be moisture-proof, dustproof, anti

oxidation.In this way, the storage life of PCB circuit board will be increased to 9

months.
About the PCB board several kinds of packaging, introduced to this.In fact, the

storage time of PCB circuit board is related to the surface treatment. Gold plating and

electric gold plating are the longest storage time. Under the conditions of constant

temperature and humidity, they can be stored for two or three years.Do a good job of

PCB circuit board storage can better extend the service life of the circuit board, is a

problem can not be ignored.
