Does anyone have design knowledge of why some manufacturers remove solder resist from the area around pads on fine pitch devices? What purpose does it serve?
I only know that it would be better for AOI as you would not have light being reflected from the solder resist coating between soldered leads as it would be a matt finish if it was removed.
