Patent ID: 7021941

Claim:
An LGA connector for interconnection between an LGA packaged integrated circuit and a printed circuit board, said LGA connector comprising: an elastomeric body, having an upper major surface, and a lower major surface opposed to said upper major surface; a plurality of tubular metallic film conductors, each connecting an upper opening on said upper major surface to an opposed lower opening on said lower major surface, each of said plurality of tubular metallic film conductors being formed by metallic deposition around said upper opening and said opposed lower opening and onto a surface of an inner wall of a through-hole connecting said upper opening and said opposed lower opening, each of said plurality of tubular metallic film conductors being insulated from one another; and each of said plurality of tubular metallic film conductors having an axial cross-section which tapers inwardly from said upper opening to form a funnel-like shape with a central through-hole; and wherein each of said plurality of tubular metallic film conductors compress radially inward in reaction to external stresses exerted against said upper major surface and said lower major surface; whereby a portion around said upper opening of each of said plurality of metallic film conductors connects to the LGA packaged integrated circuit, and a portion around said opposed lower opening of each of said plurality of metallic film conductors connects to the printed circuit board.
