Hello Richard,
HELLO ALAIN
A few things to look at:
- Did you perform a solderability test on the test coupons?
NO COUPONS WERE SUPPLIED.
- How old are these boards?
NOT ENTIRELY SURE - WE GET THEM FROM AN EXTERNAL SUPPLIER.
- Did you verify plating thickness and voiding in the test coupons?
NO COUPONS SUPPLIED.
- are your components pre-tinned?
NOT BY US. FITTED AS SUPPLIED.
