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.
