Abstract:
1. A high-speed transmission circuit board connection structure, comprising: a first high-speed transmission circuit board comprising a laminated substrate comprising a first signal transmission wiring formed on a surface thereof and a ground plane formed inside thereof; a second high-speed transmission circuit board comprising a circuit substrate and a second signal transmission wiring formed on a surface of the circuit substrate; a conductive board connecting member for fixing the first and second high-speed transmission circuit boards to a surface thereof; and a bonding wire for electrically connecting the first signal transmission wiring of the first high-speed transmission circuit board and the second signal transmission wiring of the second high-speed transmission circuit board, wherein the ground plane of the laminated structure is exposed on a side end face of the laminated substrate, wherein a conductive film is formed on the side end face of the laminated substrate such that the ground plane of the first high-speed transmission circuit board is electrically connected to the board connecting member with the conductive film, wherein the first high-speed transmission circuit board is located opposite to the second high-speed transmission circuit board such that a predetermined gap is formed between the first high-speed transmission circuit board and the second high-speed transmission circuit board, and a conductive member is filled in the gap, and wherein the conductive member is filled to reach a higher level than the ground plane of the first high-speed transmission circuit board.
