Now that is a BIG step. Stencil type: * A metal squeegee is fine with stepped stencils. * A rubber squeegee is fine with stepped stencils. Comments on step stencil "keepouts" are: * Use an ample space around the stepped down component pads that is

Step stencils are not widely used, due to: * Higher cost as compared to uniform thickness stencils * Danger of solder paste smearing at least close to the steps * Difficulty of cleaning the stepped stencil underside (the steps cannot be on the upper

What are some general guidelines for the minimum proximity of apertures to a stepdown on a stepped stencil. I have a step from 7 mils to 5 (one mil step each on the top and bottom). How far does the step need to extend beyond the apertures on the
