The length of storage is directly influenced by different surface technology.

With the condition that vacuum-packed, environment temperature 22±4°C, humidity 30%RH-60%RH.

The length of storage as below:


1.HASL: about 1 years

2.ENIG: about 6 months

3.Immersion  Tin: about 3 months

4.Immersion  Ag: about 3 months

5.OSP: about 3 months
