Hello. I think, good stencil apertures is 80% from pad. And stencil thickness is 0.15mm - 0.20mm. I use 0.15mm thick stencil almost every pcb. Sorry my very bad english but i too learning. :)

And little more... If you use chip components, then that 80% from pads is good stencils apertures size. But if you use fine pitch components, example QFP, then you can use apertures, 90% from pads. I hoping that you understand something abou

Nick: I got two choices for ya: 1 Call your supplier, have 'em send ya an outline drawing, and read the pitch from the drawing. 2 Buy a vernier caliper and measure the center to center spacing of the leads. Good luck

George: Interesting. I've found a couple of sources for antistatic Acetal. OK. To the point: I don't know, but I plan to talk to slective wave solder fixture fabricators. Several are listed in the archives Good luck

good morninrg Sal: I think if you try with no windows shape, maybe if you redce 10% (5% per side ;5% one side & 5% other side, total 10 % )

Igmar: Chrys and JAX make good points. I'd like to add that you should be careful that you don't starve larger chip components of solder when using a 4 thou stencil.
