Hopefully this is not a stupid questions but, if you are printing low tech surface mount boards, is it possible to print through a mesh screen versus a stencil? Isn't that the way it used to be done? Like soldermask only stainless steel versus polyester?? mk

Yep, did that for many years in the 80's and early 90's.

I wonder if their are suppliers that still do the emuslions? Anyone?
