Russ is correct. A 5 thou thick stencil should give good release. Here's how you run through it: * You want at least 5 solder particles across the smallest aperture. So in your case, 8 thou wide, which equals to 0.20mm gives us 0.20/5=40 microns.

I hate getting "roped" into math stuff, but here I go again ... Area of aperture = volume of paste / stencil thickness = {[5000 mil^3] / 5 mil} = 1000 mil^2 Side of the square aperture = Sqrt of the area = [1000 mil^2]^1/2 = 32 mil Diameter of ape

That's what we do [no more than three reworks or mods]. Your "four reworks permissable" was probably based on the 55110 five thermal cycles, counting wave soldering as the first cycle. How do you plan to keep track of each of those rework actions?

This works for me with ENIG finish and a SAC305 NC paste Reduce all pads by -2mil on all sides ie 0.050" x 0.050" becomes 0.046" x 0.046" EXCEPT Anything smaller than 30mil; -1.5mil Anything smaller than 20mil; -1mil Anything smaller than 15mil;

5/3 mil as in... 5 mils stepped down to 3 mils?

Indium recommendations: 0201's: * Stencil Opening = 11mil x 16mil rectangle * Foot Print = 12mil x 15mil rectangle * Stencil Thickness = 5mils * Spacing = 9mils Note: The most common stencil being utilized, is the laser cut electropolished, and in so
