HI Tony: We have the same case last month & we tried to fold a little sheet of metal (stainless steel I guess)on the fingers edge & it has worked perfectly. Only one fault among more than 1000 Pcs & it was referred to a manual error. You can try it,

Tony: Have a mask applied by the boardhouse which can be removed after soldering. We worked with pallets or tape but had bad luck with some boards. At present I would prefer a mask. M2C Wolfgang

Wolfgang: What is the mask material? What type of process/tools are required to remove it? Approximate cost per PCB?

I have had an issue where solder has contaminated gold plated pads (fingers) where it is not acceptable. The pads must remain perfectly coplaniar for a LCD zebra strip to lay accross them. Does anyone know of a way to remove the marriage level of s

Matt, have you run a profile on this board? Just because it's .062" doesn't mean that any old .062" profile will work. We have .062" thick boards that almost nil for copper and other are utilizing 2 oz. layers internally. They require quite diffe
