Patent ID: 7601919

Claim:
A system for high-speed communication between a plurality of printed circuit boards, the system comprising: a. a primary printed circuit board; b. at least one secondary printed circuit board; c. at least one multi-layer flexible conductor for sending high-speed signals between the primary printed circuit board and the secondary printed circuit board while maintaining a constant characteristic impedance between the primary printed circuit board and the at least one secondary printed circuit board, wherein the multi-layer flexible conductor enables the secondary printed circuit board to be placed at an angle with respect to the primary printed circuit board; and d. one or more signal traces for conducting the high-speed signals in the primary printed circuit board, the at least one secondary printed circuit board, and the at least one multi-layer flexible conductor; wherein the primary printed circuit board, the at least one secondary printed circuit board, and the at least one multi-layer flexible conductor are manufactured as a single piece such that the one or more signal traces are continuous conductor without encountering any connectors, junctions, or soldered regions.
