Abstract
A method for forming a space transformer (and a space transformer formed by the method) having a first plate and a second plate, the plates being separated by a frame, and electrical connectors for providing electrical connections between electrical contacts which are relatively closely spaced on the first plate and relatively more widely spaced on the second plate. The method comprises attaching first ends of wires to first electrically conductive regions on the first plate; forming insulating layers over the wires; forming electrically conductive coverings over the insulating layers; and connecting second ends of the wires to second electrically conductive regions on the second plate.
Claims31
A space transformer for providing an electrical connection between a first plurality of relatively closely spaced electrical conductors to a second plurality of relatively more widely spaced electrical conductors, comprising:
- a lower plate;
- a plurality of electrical connectors connected to said lower plate so as to be electrically connected to said first plurality electrical conductors;
- an upper plate to which said plurality of connectors is connected so as to be electrically connected to said second plurality electrical conductors;
- and
- a frame between said lower plate and said upper plate, said frame, said lower plate and said upper plate defining a closed space;
- said electrical connectors being coaxial, so as to have an internal electrical conductor, an insulator about said internal electrical conductor, and an external electrical conductor surrounding said insulator;
- and
- an electrically conductive potting material in said closed space and surrounding said external electrical conductors.
A method for forming a space transformer having a first plate and a second plate, said plates being separated by a frame, and electrical connectors for providing electrical connections between electrical contacts which are relatively closely spaced on said first plate and relatively more widely spaced on said second plate, said method comprising:
- attaching first ends of wires to first electrically conductive regions on said first plate;
- forming insulating layers over said wires by using a deposition process;
- forming electrically conductive coverings over said insulating layers by using a deposition process;
- and
- connecting second ends of said wires to second electrically conductive regions on said second plate;
- said insulating layers and said electrically conductive coverings being formed so as to extend from said first plate to said second plate.
