Hi Gil,

did you handled correctly PCB against moisture absorption ? Like guide lines of IPC-1601A ?
Shelf life of your PCB ? 
Any Baking before reflow?

Oggetto: [TN] PCB failure

Hello Tech,
We encounter a PCB discontinuing. Cross section shows conductor separation from TH.
The PCB manufacturer claims it is due to overheating during assembly. To me, it looks like bad PCB manufacturing.
Please look at the picture and give me your feedback.
Thank you
