Claims
- 1. An electrical circuit comprising:
- a dielectric substrate;
- a pattern of conductive traces on one side of said substrate and positioned substantially on the surface of said one side, said traces collectively lying in and defining a trace surface and being made of a conductive material; and
- at least one of said conductive traces having a three-dimensional conductive circuit feature formed integrally therewith and projecting from said trace surface in a first direction for providing a readily connectable and disconnectable pressure interconnection to another element at said one side of said substrate, said three-dimensional conductive circuit feature consisting essentially of the conductive material of said conductive trace shaped to form a back side depression, and a rigid high strength material filling said depression, one of said traces including a second three-dimensional conductive circuit feature formed integrally therewith and projecting at least partly through said dielectric substrate in a direction opposite said first direction for connection to another element at a second side of said substrate.
- 2. The circuit of claim 1 wherein said dielectric comprises an electrical connector wafer and wherein a plurality of said traces are formed with integral projecting features, said features defining interconnection sites extending from and above the surface of said dielectric wafer for electrically connecting said traces to a second electrical circuit.
- 3. A three-dimensional electrical circuit comprising:
- a substrate having first and second sides, and
- a plurality of conductors on said first side having outer surfaces lying in and defining a conductor surface, at least some of said conductors having forward raised contact features integral therewith and projecting in a first direction from said conductor surface away from said substrate for providing a readily connectable and disconnectable pressure interconnection to another element at said first side of said substrate, said contact features and said conductors consisting essentially of a conductive material having poor structural characteristics, at least some of said contact features having a back side depression filled with a contact feature rigidifying high strength material, at least one of said conductors having a rearward raised feature integral therewith and projecting from said conductor surface through said substrate in a direction opposite said first direction for connection to another element at said second side of said substrate.
- 4. A three-dimensional electrical circuit comprising:
- a substrate having first and second sides, and
- a plurality of conductors on said first side having outer surfaces lying in and defining a conductor surface, at least some of said conductors having contact features integral therewith and projecting from said conductor surface in a first direction for providing a readily connectable and disconnectable pressure interconnection to another element at said first side of said substrate, said substrate having at least one hole there through, and a post feature integrally formed with one of said conductors and projecting through said substrate hole in a direction opposite said first direction for connection to another element at said second side of said substrate.
- 5. The circuit of claim 3 including a ground shield secured to said second side of said substrate, said rearward raised feature projecting through said substrate into contact with said ground shield to provide a through-the-substrate connection from said ground shield to conductors on said first side of said substrate.
- 6. The circuit of claim 5 including a first non-conductive coverlay covering said first side of said substrate and said conductors, said coverlay having a hole that receives said forward raised features.
