Hi Fred, I agree with Paul; leave it up to the assembly house, since they have the most experience in the actual soldering process. If they want to change a particular stencil aperture, they probably have good reason to do so. BRgds, Roger M.

I was never asked and just assumed that you generate the stencil pad sizes the same size and let the stencil house size pads down as required... Can someone clarify this for me...?
