The IPC-7351C standard was proposed as a complete rewrite of IPC-7351B, introducing proportional pad stacks, rounded rectangle pads, and contour courtyards. After the passing of key architect Dieter Bergman, the draft was ultimately scrapped in favor of the newer IPC-7352 standard. For further discussion on the draft, visit the PCB Libraries Forum .

The standard now recommends rounded rectangles over traditional oblong shapes to provide better paste release and more consistent solder fillets.
