Patent ID: 7439516

Claim:
A computerized tomography imaging scanner module comprising: a plurality of scintillators; a plurality of back-illuminated photodiodes optically coupled with said scintillators; a multi-layer substrate comprising a first surface, a substantially parallel second surface opposing said first surface, and a groove defined within said second surface, said photodiodes are coupled to said first surface, said first surface having a plurality of substrate electrical conductors to which said photodiodes are electrically coupled, and each of said plurality of substrate conductors is connected to a different one of said back-illuminated photodiodes; a flexible electrical circuit coupled to said substrate second surface, said flexible electrical circuit having a plurality of flex electrical conductors to which said substrate second surface is electrically coupled, wherein each of said plurality of flex electrical conductors is connected to a different output of said substrate second surface; and a plurality of metallized sacrificial pads coupled between said substrate and said flexible electrical circuit adjacent to said groove within said substrate, wherein each of said plurality of metallized sacrificial pads is separated from an adjacent sacrificial pad by a gap.
