Abstract
Abstract Connector and processes for preparing same for demateably interconnecting arrays of contact pads. The connector has a preformed elastomeric sheet-form member provided with a series of apertures through each of which an electrically conductive plated metal deposit extends. An integral end of the deposits protrudes outwardly beyond a surface of the sheet-form member, forming contact surfaces for demateably engaging the pads.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
248 words
In a sheet-form, demateable interposer member for insertion between, conforming to, and forming electrical connection with high density patterns of electrical contacts on opposed surfaces, useable for example to connect printed circuits with a computer chip package, the sheet-form body and individual plated electrically conductive elements extending through the thickness of the sheet-form body, terminating beyond opposite faces of the body for electrical engagement with respective contacts of said patterns, the improvement wherein, with said sheet-form body member being comprised of a compliant elastomeric substance selected to conform under compression to minor variations in the planarity of said opposed surfaces when the opposed surfaces are clamped together with the interposer member placed in between, said plated electrical elements comprise a uniform x, y array of electrically independent, miniature plated copper members comprising profiled posts plated in substantially straight holes pre-drilled through the thickness of said thin compliant sheet-form body member, said holes and plated posts being about 0.004 inch or less in diameter, present at spacings of about 0.008 inch or less, said profiled posts of said uniform array characterized by having at each end of each miniature plated post, integral, plated copper enlarged portions overlying the surface of said thin conformable sheet-form body member substantially symmetrically about the periphery of each pre-drilled hole, sufficiently to hold the respective miniature plated metal contact member axially in place in the thin conformable sheet-form body member during handling as it is inserted or removed from between said arrays of contacts.
Claim 2
Dependent Claim
