Abstract:
1. An implantable device comprising: an electrically non-conductive substrate; a plurality of electrically conductive vias through said electrically non-conductive substrate; a plurality of metal traces on said electrically non-conductive substrate electrically connected to said conductive vias; a braze stop on said electrically non-conductive substrate and along a periphery of said non-conductive substrate surrounding said plurality of metal traces, and separating a braze joint from said plurality of metal traces; said electrically non-conductive substrate, said traces, said braze stop trace, and said electrically conductive vias forming a base; a flip-chip circuit attached directly to said base using conductive bumps; a second circuit attached directly to said base; and a cover brazed to said base at said braze joint, said cover, and said base forming a hermetic package; wherein said flip-chip circuit and said second circuit are adjacent to each other, and mounted to a common substantially planar surface of said base and said braze stop trace prevents said braze from contacting said metal traces.
