Dear All,

 

Recently, our SMT detected some failures with solder can't extend on test
point of bottom side of OSP boards, all failures board with a common
phenomenon and same date code: discoloration at top side after bottom side
reflow. We suspected that the failure is related to OSP film quality issue.
But I don't know how to prove my suspected. I will send some pictures to
Steve. So you all can see them.
