Subject:        [TECHNET] Solder Stencil Guidelines Wanted...

Does anyone have a set of Solder Paste Stencil Design Guidelines they could
share with me?  I wish to build a standard set of guidelines to simplify our
stencil design.  Ideally it would address stepped stencils, coarse and fine
pitch on the same PCB, etc, but anything would be acceptable.

Thanks,

Mike Lang
