Interconnection for conductor assemblies having closely spaced conductive lines

Claim 1

An electrical structure comprising: a first conductor assembly having a first insulating support of a generally rigid material such as glass and a first set of conductive lines on a surface of said first support, said lines extending generally parallel and having a predetermined spacing that does not vary significantly; a second conductor assembly having a second insulating support and a second set of conductive lines on a surface of said support, said second insulating support being of a thin, flexible, plastic material such that said conductive lines of said second set are formed and maintained less accurately than the conductive lines of said first set, said lines in a first region of said second set having a spacing that varies progressively from a spacing that is greater than said predetermined spacing of said first set to a spacing that is less than said predetermined spacing of said first set, whereby said predetermined spacing of said first set exists along a line in said first region of said second set regardless of variations in the spacing between lines of said first and second sets within predetermined tolerances; a thin insulation layer covering the regions of said first conductive lines closely adjacent to said line in the region where said spacing of said first lines is less than the spacing of said second lines, and; means including resilient pads connecting said first and second conductor assemblies to make electrical contact along said line.
