Patent ID: 7645641

Claim:
A method comprising steps of: placing an electronic circuit on a substrate, the electronic circuit comprising a topography of more than one level; preforming a first surface of a compliant interface to the topography of the electronic circuit; wherein the compliant interface is constructed from a compliant material and wherein said preforming comprises steps of: embedding flexible supports in a temporary support material, wherein said temporary support material is sized according to dimensions of the electronic circuit; shaping a first surface of the temporary support material according to the topography of the electronic circuit; attaching a compliant membrane to the first surface of the temporary support material; attaching a permanent bottom structure to the temporary support material; attaching surrounding supports to the temporary support material; and removing the temporary support material; and loading the preformed compliant interface over the electronic circuit so that the preformed compliant interface interlocks with the electronic circuit, matching contours of the electronic circuit when said preformed compliant interface is loaded over said electronic circuit.
