Carol, I think the guys are right about you stand off problem but I want to address the wrinkleing of your masking. Although I think the temps you are subjecting the board to are very high and more than likely creating problems of their own. I th

Several methods work well. 1. (Low Volume Method) Using an Xacto blade, scrape off the solder mask holding the blade flush being careful not to use the pointed part of the blade. 2. (High Volume Method)Tape off the area that you don't want the mas
