Abstract:
A method of forming an electronic structure, comprising:providing a substrate having a first electrically conductive pad on a surface of the substrate; forming an uncured adhesive layer on the surface of the substrate; placing an electrically conductive stiffener on the adhesive layer, wherein the uncured adhesive layer mechanically couples the stiffener to the surface of the substrate and electrically couples the stiffener to the first electrically conductive pad; and curing the uncured adhesive layer, wherein the step of forming an uncured adhesive layer comprises; forming an electrically conductive contact on the first electrically conductive pad; and setting a dry adhesive on the substrate, wherein a hole in the dry adhesive includes the electrically conductive contact, wherein after the placing step the electrically conductive contact electrically couples the stiffener to the first electrically conductive pad, wherein the curing step includes curing the dry adhesive and curing the electrically conductive contact, and wherein after the curing step the dry adhesive adhesively couples the stiffener to the substrate, and wherein the hole in the setting step includes a gap between the dry adhesive and the electrically conductive contact.
