Yes, OSP coated PCB need to be used within different storage periods, which
is depend on the conditions of the environment , such as in PCB mfg
production line or in SMT line, the Max storage period is about 7 days after
it is opened, otherwise, OSP rework is need before assembly

 

Thanks!

Hi,

 

Is it true when a PCB is OSP coated it needs to be populated within 24 hrs

of opening the package due to oxidation?

 

Thanks,

JW
