Abstract
An electric circuit assembly (10) is provided by a ceramic base substrate (14), a copper ground plane (20) directly bonded to the base substrate, an intermediate ceramic substrate (22) directly bonded to the ground plane, and a copper lead frame (24) having a pad portion (26) directly bonded to the intermediate substrate. The base substrate extends laterally beyond the ground plane and intermediate substrate. The lead frame has an extension portion (32) extending laterally beyond the intermediate substrate, ground plane and base substrate, and spaced above the base substrate by the thickness of the ground plane and intermediate substrate. The lead frame extension portion is bent upwardly from the pad portion along a bend line spaced laterally inwardly of the outer edge (18) of the base substrate.
