Abstract:
1. An electronic apparatus comprising: a first electronic module and a second electronic module, each having a maximum thickness of no more than 90 microns, each comprising at least one flip chip integrated circuit mounted on a substrate, wherein the substrate has an edge connection pattern comprising connection pads on each of a top side and a bottom side, the bottom side opposite the top side, of the substrate; wherein a first set of connection pads on the top side of the edge connection pattern of the first electronic module is separated from an opposing second set of connection pads on the bottom side of the edge connection pattern of the second electronic module by less than 15 microns, wherein each pad of the first set of connection pads is conductively connected directly to an opposing pad of the second set of connection pads, wherein the electronic apparatus has a resultant edge connection pattern comprising connection pads on the bottom side of the first electronic module and on the top side of the second electronic module, and wherein a thickness of the resultant edge connection pattern of the electronic apparatus is compatible with an edge connector, and wherein a size and arrangement of the pads of the resultant edge connection pattern are compatible with the edge connector.
