Abstract
Abstract A method of interconnecting parallel circuit boards, including and principally for, memory planes, comprises bonding one end of a flat flexible cable to the edge of a first board, and connecting the word straps or other leads directly to the flat flexible cable. The other end of the flat connector cable is then directly connected to the end of a similar flat flexible conductor cable (connected at its opposite end to the word straps or other leads of a second board), thereby completing the interconnection.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
162 words
A method of interconnecting two printed circuit boards comprising the steps of: bending one end of a first strip of flat flexible conductor cable, stripped of the insulation on one side adjacent the ends thereof, in a generally U-shape; bonding said first strip of flat flexible conductor cable intermediate its ends to a first circuit board; connecting the bent-over end of said first strip of flat flexible conductor cable to the circuitry on said first circuit board; bending one end of a second strip of flat flexible conductor cable, stripped of insulation on one side adjacent the ends thereof, in a generally U-shape; bonding said second strip of flat flexible conductor cable intermediate its ends to a second circuit board; connecting the bent-over end of said second strip of flat flexible conductor cable to the circuitry on said said second circuit board; and interconnecting the opposite ends of said first and second strips of flat flexible conductor cables to complete the interconnection.
Claim 2
Independent Claim
162 words
A method of interconnecting two printed circuit boards comprising the steps of: bending one end of a first strip of flat flexible conductor cable, stripped of the insulation on one side adjacent the ends thereof, in a generally U-shape; bonding said first strip of flat flexible conductor cable intermediate its ends to a first circuit board; connecting the bent-over end of said first strip of flat flexible conductor cable to the circuitry on said first circuit board; bending one end of a second strip of flat flexible conductor cable, stripped of insulation on one side adjacent the ends thereof, in a generally U-shape; bonding said second strip of flat flexible conductor cable intermediate its ends to a second circuit board; connecting the bent-over end of said second strip of flat flexible conductor cable to the circuitry on said said second circuit board; and interconnecting the opposite ends of said first and second strips of flat flexible conductor cables to complete the interconnection.
Claim 3
Independent Claim
87 words
A method of interconnecting two printed circuit board comprising the steps of: providing two strips of flat flexible multi-conductor cable, each multi-conductor cable stripped of the insulation on one side adjacent the ends thereof; bonding the insulated surface of one end of each cable to a respective circuit board; electrically connecting and bonding the circuitry of each board to the respective conductors of the adjacent flat flexible multi-conductor cable; and electrically interconnecting and bonding the opposite ends of said flat flexible multi-conductor cables to complete the interconnection.
Claim 4
Independent Claim
87 words
A method of interconnecting two printed circuit board comprising the steps of: providing two strips of flat flexible multi-conductor cable, each multi-conductor cable stripped of the insulation on one side adjacent the ends thereof; bonding the insulated surface of one end of each cable to a respective circuit board; electrically connecting and bonding the circuitry of each board to the respective conductors of the adjacent flat flexible multi-conductor cable; and electrically interconnecting and bonding the opposite ends of said flat flexible multi-conductor cables to complete the interconnection.
Claim 5
Dependent Claim
37 words
A method of interconnecting two printed circuit boards as in claim 2, wherein the boards are disposed in parallel relationship, and including the additional step of tucking the interconnected flat flexible multi-conductor cables between said circuit boards.
