(except Grid Array) then that should improve fabrication, stencil paste application, assembly reflow and inspection. I believe Rounded Rectangle pad shape is the future for several reasons, but the top is "all stencil apertures are created using laser technology and that produces a corner radius on the SMT aperture openings
