Mine may be an old question.  It may even have a redundant, old,
answer.  However, I feel that I must ask.  Is there a way, or is it even
realistic to consider, to screen Hysol SR1010 "Wet" soldermask with less
than 0.010" annular ring?  Now, I know that it can be done.  We do it. 
Yet, can PRODUCTION runs be considered?
	Here are our specifics.  One, we are told that our Magna-cure 70
capilary emulsion is the best choice.  Two, we are using Saatilene
Hitech, 110.80, screen mesh.  And third, a 70 durometer squeegee.  (main
focus on auto-screening)
	In an effort to keep this brief, I wont bore you with other issues. 
However, I just can't seem to accept the fact that our industry isn't
screening less than 10mil annulars.  Again, when we do, I don't want to
get into discussions about "screening paper".  Or, if we do it be
hand...
