Connectors are provided for propagation of electrical signals in a plurality of closely spaced propagation paths, such as between circuits connected to conductive pads of circuit boards, each circuit presenting a certain characteristic impedance at a pad connected thereto. For example, each connector includes a plurality of resilient and electrically conductive signal-propagating interconnect means having opposite ends engageable with conductive pads on a pair of the circuit boards. The interconnect means are supported by insulating means of a support structure which also provides conductive ground means in adjacent relation to the conductive interconnect means. The conductive ground means are arranged for connection to grounding elements of the circuit boards. The configuration and characteristics of the ground conductor means and the insulating means in relation to each signal-propagating interconnect means are such as to obtain a certain characteristic impedance for matching the characteristic impedances of circuits interconnected by each signal-propagating interconnect means.
A method of providing connections between conductors of a plurality of stacked circuit boards to provide paths for signal propagation between circuits on said boards having a certain characteristic impedance, the steps of providing for installation between each board and a board adjacent thereto a connector including support means arranged to receive and support compressively resilient and electrically conductive signal-propagating interconnect means for pressure engagement of opposite ends of the signal-propagating interconnect means with conductive pads of the circuit boards, providing such signal-propagating interconnect means in openings through said support means, providing ground conductor means in the support means having portions in adjacent relation to the signal-propagating interconnect means, providing ground connection means for connecting the ground conductor means to ground conductors of interconnected circuit board circuits, providing insulating means of dielectric material included in the support means for supporting the signal-propagating interconnect means within the openings therein and in electrically insulated relation to adjacent portions of the ground conductor means, and providing configuration and characteristics of the ground conductor means and the insulating means in relation to each signal-propagating interconnect means such as to obtain a certain characteristic impedance which matches the characteristic impedances of the circuits of the circuit boards interconnected by each signal-propagating interconnect means.
