Electrical interconnection method and apparatus utilizing raised connecting means

An electrical connector adapted to interconnect with a mating electrical connector comprising:

• a substrate;
• electrically conductive material on said substrate having sites defining positions of electrical interconnections;
• electrically insulative projections of substantially inelastic dielectric material affixed to and projecting from said sites;
• and
• an electrically conductive layer on and supported by each of said projections and on and electrically coupled to said electrically conductive material adjacent thereto;
• said conductively layered projections comprising conductively layered walls wherein said walls comprise enclosures which are sized and shaped to mate with a plurality of conductively layered projections on said mating electrical connector.

A method for enabling interconnection of a first electrical connector with a mating electrical connector comprising the steps of:

• for the first connector, placing electrically conductive material on a substrate having sites defining positions of electrical interconnections;
• affixing electrically insulative projections comprising walls of substantially inelastic dielectric material to the sites;
• placing an electrically conductive layer on and supported by each of the projections and on and electrically coupled to the electrically conductive material adjacent thereto;
• providing the mating electrical connector with electrically conductive pads having areas disposed to mate with at least respective ones of the projections having the electrically conductive layers thereon;
• and
• sizing and shaping the walls as enclosures with the conductive layer thereon which are thereby matable and elec-trically interconnectable with a plurality of the conductively layered projections on the mating electrical connector.
