You want to use a rubber squeegee with as high as a durometer as you can get away with, order two or three sets of blades starting with the softest and then progress up the the hardest, the reasoning behind this is the softer squeegees will wear out

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

Hello. Sometimes metal squeegees DO work with stepped stencils. You will always get much better results with metal squeegees compared to polymer blades. The only requirement for the metal squeegee to work, you need about 0.06 in clearance for eve

I wouldn't recommend a metal squeegee, because if you can't wipe the step-etched area completely clean (that's the problem with metal) you'll have problems with the definition of the fine-pitch (it may stick in the holes). Best is a 70 Shore polyuret

Care must be taken to not apply an excess of material, as the adhesive will flow under the device during placement and curing, and could cause a short. Printer setup: * Don't worry about stencil thickness. A wide range of stencil thicknesses (typic
