1). Most stencil manufacturers can produce a stencil with a tolerance of
less than 0.5mil, but only if you work from electronic data. So if tolerance
is important, don't send a film and a sketch to a stencil manufacturer ---
send them an electronic file (Gerber 274X is the preferred format, other
formats can be used) showing the apertures you want. You can send a separate
electronic drawing file of the step-and-repeat data, etc. If you do send a
film and sketches, be prepared for some loss in accuracy.
2). Most stencil manufacturers (including A-Laser, ooooops no plugs.) have a
website where you can find an order form which includes almost all the
questions they may want to ask you.
3). That depends mostly on YOUR ISO document. What does it say you need to
do? If it says that you have to verify that your supplier can supply you
with good stencils, go try out the supplier.
4). Ehhh, may be I should pass on this one, but I can give you some
suggestions by phone.

Technetters--
I need some information I hope you can supply:
1) What do I need to supply a stencil manufacturer to get a stencil made?
Will a 1:1 artwork of the pads and an array drawing suffice?
2) How do I document that information? Stencil Drawing? Work sheet? Other?
3) How should I control it so that I meet ISO?
4) Any recommendations on stencil manufacturers?
As always TIA,
