Stencil thickness could be 3,4,5,6 mil but stencil is framed on 29 inch frame for SMT printer machine. I want to measure thickness in the center of this frame.

I do not know of a way to measure the nano-coating. However, it is easy to check if it is still on the stencil. Simply use a 'sharpe' pen and try and mark the bottom (PCB) side near any openings. If it easily marks, then the nano is no longer present

You don't really need to measure the center's thickness unless there is where the step up/down is at. As long as you can measure the the outer edge of the stencil, it would be the same thickness.

There are some "rule of thumb" design approaches for circle apertures for BGA's. Does anyone use rule of thumb formulas for square/squircle apertures for BGA? If so, what are they?

Cal is correct. Sipad, Precision Pad, Optipad, SSD, and all that were a feeble Euroland approach to creating flat pads for fine pitch assembly. To begin with, they required a complete board redesign using their proprietary software. [Oooo, me firs

Hello All, The audacity to yell Smartsonic here is appauling. This is a process approach dependent on the type of epoxy. To suggest your equipment without knowing a thing about the process is shameless. OK, now I'll get off my soap box. The low
