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.

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, Jeffrey A.
