If you are using a photo defined solder mask, you can control which pads are covered/filled and which pads are cleared. Bob Metcalf Morton Electronic Materials >>> Barry Darnell <[log in to unmask]> 10/14/96 11:41am >>> I have run into a problem with a board that has vias in smt pads. We need all of the vias plugged, and I am told that solder mask is the best way to do that. This is to ensure that a good vacuum is maintained for our ATE equipment. That is the problem. I can not have a via covered with solder mask on top of an smt pad. The board house I am using says this is difficult for them because they have to determine which vias are plugged and which are not. Anyone out there with any suggestions? Thanks, Barry Darnell (864)627-8800 Ext. 231 [log in to unmask] CD Electronics, Inc.
