High Density, High Performance Memory Circuit Package

View page
US Patent:
52688151, Dec 7, 1993
Filed:
Jul 30, 1992
Appl. No.:
7/922257
Inventors:
Thomas M. Cipolla - Katonah NY
Paul W. Coteus - Yorktown Heights NY
Brian C. Derdall - North York, CA
Christina M. Knoedler - Peekskill NY
Alphonso P. Lanzetta - Marlboro NY
John J. Liutkus - Yorktown Heights NY
Linda C. Matthew - Peekskill NY
Lawrence S. Mok - Brewster NY
Irene A. Sterian - Toronto, CA
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H05K 720
US Classification:
361704
Abstract:
A high density circuit package includes a pair of planar packages, the planar packages exhibiting front and back surfaces and positioned back-to-back in the high density circuit package. Each planar package includes a flexible circuit carrier having a plurality of circuit chips mounted thereon. Front and back planar metallic heat sinks sandwich the circuit carriers, at least one of the heat sinks contacting a surface of the chips mounted on the sandwiched circuit carriers. Each heat sink is provided with air flow apertures formed in its planar surface and adjacent to each circuit chip. A circuit card interconnects with the circuit carriers in an interconnection region and is pluggable into a female connector. The planar metallic heat sinks and circuit carriers are mechanically packaged so as to provide a planar arrangement which aligns the apertures in both the front and rear heat sinks. A pair of planar packages are mechanically connected in a back-to-back arrangement so that the apertures therebetween are aligned.
