US Patent:

6705006, Mar 16, 2004
Filed:

Jan 3, 2003
Appl. No.:

10/335986
Inventors:

Jeffrey C. Baechtle - Vestal NY
Stephen R. Howland - Vestal NY
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

H05K 302
US Classification:

29847, 29839, 29857, 174251, 174266, 361773, 361761
Abstract:

Electrical nets are prepared by bonding an electrically conductive element in a deleted plated via. The electrically conductive element has a headed portion that contacts the bottom of the laminate and the other end of the electrically conductive element electrically connects to a BGA pad or surface trace line.

6819813, Nov 16, 2004
Filed:

Sep 11, 2002
Appl. No.:

10/242152
Inventors:

Stephen R. Howland - Vestal NY
John U. Knickerbocker - Wappingers Falls NY
Steven P. Ostrander - Wappingers Falls NY
Martin L. Schmatz - Rueschlikon, CH
Assignee:

International Business Machines Corporation - Armonk NY
International Classification:

G02B 612
US Classification:

385 14, 385 9, 385 27, 385 39, 385129, 385131, 385132, 438 25, 438 26, 438 28, 372 43
Abstract:

An apparatus for integrating optical devices between a module and a circuit board comprising a carrier having optical waveguides, a module having optical ports on a surface of the module, the surface of the module connected to the carrier such that the optical waveguides are in communication with the optical ports; and a circuit board having optical ports on a surface of the circuit board, the surface of the circuit board connected to the carrier such that the optical waveguides are in communication with the optical ports. The apparatus may also integrate electrical ports on the surface of the module, the surface of the circuit board, and electrical connections on the carrier. The apparatus may also integrate circuit chips having optical ports for communication with the optical waveguides.
