Abstract
Methods and apparatus for an assembly having first and second circuit cards mated together with a ball stack on the first circuit card extending into a through hole in the second circuit card. A wirebond connects the first ball stack to a bond pad on the first surface of the second circuit card forming a low profile connector-less interconnect. The ball stack comprises at least two balls stacked on top of each other and bonded to each other, wherein the balls are generated from wire.
