Hi all. A recent board has shown some issues with graping and non-wetting on some 0402 capacitors. I believe we have the issue sorted. A combination of a 4 mil stencil with 2 mil reduction not giving us enough paste, and too long of a soak profile.

MTBF is hard to nail down raw data based on whether or not it is classified as IPC CII or CIII alone. Given that most failures are environmentally based, you might be able to get this data for CII and CIII in similar environmental testing situations

Is it correct that there is nothing direct in Class III documentation that states these boards should not be reworked? Whether these boards are allowed to be reworked is strictly a decision / agreement between assembler and customer . . . correct?

Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A
