Maybe what you could do is have the stencil contain a tightly spaced mesh or grid of openings over the ground plane areas that you need to be solder covered. Also, to help the solder flow out better, you might want to decrease the percentage of metal

I stripped the entire board because I had to have the boards troubleshot. Had a high failure rate from the field. The board coating was applied about 5 months ago. I was told by my people anything past 3 days and you will need this type of stripper

Has anybody ever use this method to reclaim the solder from dross. I tested this $10 gadget, it's used to press potato to make mash potato. The result is comparable to a $20k machine that basically does the same thing, i.e.: compress dross to squeeze

Okay, I've done extensive Google and SMTnet Archive searches, and I've turned up nothing but Patent Ideas. We've got a new application with which I'd like to fill a cavity containing a wire with molten solder. The cavity is housed within a large Mil
