Hi Danny, I would suggest a laser-cut stencils w/ anti static polymer film. For more information on the stencil you should consider engineering lab. They provide high quality stencil for a reasonable price. If you can find a laser-cut stencil for a

Hi all, We are currently having problems with a laser-cut stencil that is electropolished and nickel plated with 9-mil openings. The paste does not release well from the apertures. We are having to wipe after every print. The board is fixtured well a

Electropolishing definitely improves the print characteristics of both Laser-cut and Chem-etch stencils. The caveat here is avoid over polishing which results in rounding of the edges and/or enlargement of the openings. Over polishing is typically th

Laser cut offers the following two major advantages... the aperture tolerance is much better and the trapezoidal apertures are more consistant. For the small difference in price, you get the assurance of

Electroformed stencils cost about twice as much as other stencils, but they to have better paste release characteristics than laser cut stencils.
