Just a quick industry capability questions. Are board manufactures still having trouble holding mask dams between fine pitch (19mil) SMT pads. As recent as a year or so ago I was under the impression that board shops would ask the remove these small dams when they got them on the Gerber data. Is this still common. I am interested in what most people think is feasible regarding mask dams that are 4 mils wide and smaller. All responses are appreciated.
