Patent ID: 7495330

Claim:
An apparatus for use with a printed circuit board (PCB) having a plurality of electrical contacts disposed on said PCB, comprising: an interposer which includes a substrate having a first side adapted to be bonded to said PCB, a second side disposed opposite the first side, and a first plurality of columnar conductors extending through said interposer substrate, each of said columnar conductors being adapted to be electrically connected to a PCB contact; and a patch substrate having a first side bonded to said second side of said interposer substrate, a first plurality of contacts disposed on said first side of said patch substrate, each contact being physically and electrically bonded to a columnar conductor of said interposer substrate, a second side disposed opposite the first side of said patch substrate, a second plurality of contacts disposed on said second side of said patch substrate, a second plurality of columnar conductors extending through said patch substrate from said first side to said second side of said patch substrate and spaced from said first plurality of contacts on said first side of said patch substrate, and a plurality of conductor lines disposed on said first side of said patch substrate and electrically connecting columnar conductors of said second plurality of columnar conductors to contacts of said first plurality of contacts on said first side of said patch substrate; each of said second plurality of columnar conductors being electrically connected to a contact of said second plurality of contacts of said patch substrate.
