Simply ask your board manufacturer to Hot Air Solder Level the boards. HASL is a very common procatice at all board houses. Should not add cost and now your board meets this spec before you even touch it.

Is there a guideline for the manufacturing of PC Boards? I find that my board changes dramatically from board house to board house, causing about 2% failure rate.
