Footprint Expert has a Calculator for autogenerating land patterns from standard package dimensions. Due to all the package dimensions including terminal dimensions can determine the pad stack size and pad stack collisions. This is what the Through-hole Minimum Pad to Pad Clearance was intended for. Two pads should never touch each other when 'Calculating' a land pattern.
For all non-standard packages, Footprint Expert has FP Designer for creating land patterns from the component manufacturers datasheet. If you use the manufacturers recommended pattern, there will be instances where 2 or 3 pads touch each other. Even through-hole and surface pads can intersect. Adding a minimum pad to pad clearance to FP Designer doesn't make any sense. There are rules for Calculating patterns. There are no rules for mfr. recommended patterns. |
