PB unsoldering

The LPI solder mask used makes it *extremely difficult* to delaminate unless you: a) are using an iron not regulated to 700F b) are not removing all the solder and/or you are not first detaching the lead from the *inside edge* of the plated-thru hole. In many cases, a lead 'sticks' to the inside plating. You have to gently wiggle it side-to-side after 'solder-sucking' before pulling. The resistor/cap holes used on the boards is *oversized* as compared to 'commercial' boards. This was done *on purpose* to make it easier to desolder. In 5 years, I've personally never delaminated any MOTM pc board. Paul S.
