Ed,
In the past, it has been standard practice here to ask that of
customers. We have recently (within the past twelve months) acquired the
knowledge and capability to achieve fine pitch dam's between pads. Our best
effort to date has produce uniform solder mask dams between pads down to 15 mil
which were 2 mils themselves.
We are capable of maintaining dam's down to 4 mils on a
consistent basis.
I am of the believe that this is where things are headed
anyway.
Hope this helps.

Hi all,
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.
