High data rate coaxial interconnect technology between printed wiring boards

A system for electrically interconnecting circuit boards, the system comprising:

• a first circuit board having a first signal conducting means formed therein, the first signal conducting means being shielded by a first electrically conductive shield, the first electrically conductive shield having a first opening formed therein so as to expose the first signal conducting means in the first circuit board;
• a second circuit board having a second signal conducting means formed therein, the second signal conducting means being shielded by a second electrically conductive shield, the second electrically conductive shield having a second opening formed therein so as to expose the second signal conducting means in the second circuit board;
• and
• an electrically conductive material surrounding at least one of the first and second openings and within at least one of the first and second openings;
• wherein the first circuit board and the second circuit board are electrically interconnected by the electrically conductive material such that the first opening and the second opening are aligned and the first signal conducting means is electrically interconnected to the second signal conducting means.
