Hi Randy: This is an idea. Make a template slightly larger than the area needed to be cleaned ( 5/8" ) and place it over the area. Use a wide solder iron tip, that has been sharpened, to scrap off the solder mask. It should be a very fast operation, maybe twenty seconds per.

Ask your fab house to repair for you by hand - taking mask off a tooling land/hand tinning is not hard. There are also some repair houses that will do this also. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Randy Bock Sr. Sent: Thursday, November 10, 2005 2:53 PM To: [log in to unmask] Subject: [TN] Solder Mask Removal Hey y'all, We have several hundred boards that are supposed to have the solder mask removed for around a mounting hole on the back side of the board. The fab house missed. We are faced with a total remake if I cannot find some way to remove the solder mask relatively easy. Most are still fab boards, but I do have some that are assembled. Any ideas would be appreciated. The clear area has to be approx 1/2 " dia.
