Hello All

One customer of us wants to keep an assembled FR4 Product (soldered with
SnPb) for 4 days at 150°C to verify one component.
What do you expect in regard to the components / PCB,....?
How thick will the inter metallic phase be after that time.
Will the mechanics of the solder joint still be reasonable?

Siggi
