Abstract:
An electric connection assembly for transmission of high speed signals and power and ground voltage levels from one point in an electrical circuit to another, comprising:(a) a printed circuit board (PCB) having a contacting edge, at least one logic signal line, and at least one power and ground line, having a contact tab connected to the logic signal line, and power and ground conductors affixed to the contacting edge and electrically connected to the power and ground lines, the logic signal line and the power and ground lines being positioned to provide a desired transmission line impedance; and(b) a connector for receiving the PCB, the connector adapted to be mounted on a substrate and having at least one logic contactor for electrically connecting to the contact tab, the logic contactor being configured to firmly contact the contact tab and to the substrate to close a secondary contact of the logic contactor at a point on the logic contactor very near the substrate to minimize the length of the logic signal path formed by the contact tab and the contactor and the substrate, the connector having at least one power or ground contactor for electrically connecting to the power or ground conductor, and to the substrate the power or ground contactor being configured to firmly contact the power or ground conductor at a contact point on the power or ground contactor very near the substrate to minimize the length of the signal return path formed by the power or ground conductor and the power or ground contactor and the substrate, the logic contactor point and the power or ground contactor contact point being positioned adjacent each other to aid in maintaining the approximate desired transmission line impedance.
