Abstract
Abstract A multilayer circuit prototyping board for prototyping circuits in a three-layer transmission line structure. The multilayer circuit prototyping board includes grooves and mesas on one side thereof, with wires to be run in the grooves for interconnecting electronic components. The electronic components are mounted on the bottom surface of the prototyping boards with leads protruding through holes in a bottom ground plane into the grooved portions. Wires or solder bridges are located within the grooves for interconnecting the leads of the various electronic components. A removable top ground plane is then placed atop the board base for completing the three-layer structure.

Claim 1
Independent Claim
211 words
A transmission line structure adapted for receiving electronic components having leads, and conductors to interconnect the electronic components, said transmission line structure comprising: a base member having a conductive layer and an insulative layer, wherein a plurality of mesa portions are formed in said insulative layer, and wherein said mesa portions define grooves therebetween, and wherein said mesa portions have a conductive upper surface and are in electrical contact with said conductive layer; wherein said base member includes a plurality of plated-through holes from said conductive layer to said grooves, and wherein each one of said plurality of holes terminates in a conductive pad on the mesa-side of said base member; wherein said base member is adapted to receive electronic components on the conductive layer side with a lead of an electronic component extending through one of said plurality of plated-through holes; wherein said grooves are adapted to accept conductors for interconnecting the electronic component leads; a top member including a conductive plate and a plurality of conductive deformable members in electrical contact with said conductive plate, wherein said top member is placed atop said base member such that one of said deformable members contacts said conductive upper surface to establish electrical contact between said conductive plate and said conductive layer.
Claim 2
Dependent Claim
211 words
A transmission line structure adapted for receiving electronic components having leads, and conductors to interconnect the electronic components, said transmission line structure comprising: a base member having a conductive layer and an insulative layer, wherein a plurality of mesa portions are formed in said insulative layer, and wherein said mesa portions define grooves therebetween, and wherein said mesa portions have a conductive upper surface and are in electrical contact with said conductive layer; wherein said base member includes a plurality of plated-through holes from said conductive layer to said grooves, and wherein each one of said plurality of holes terminates in a conductive pad on the mesa-side of said base member; wherein said base member is adapted to receive electronic components on the conductive layer side with a lead of an electronic component extending through one of said plurality of plated-through holes; wherein said grooves are adapted to accept conductors for interconnecting the electronic component leads; a top member including a conductive plate and a plurality of conductive deformable members in electrical contact with said conductive plate, wherein said top member is placed atop said base member such that one of said deformable members contacts said conductive upper surface to establish electrical contact between said conductive plate and said conductive layer.
Claim 3
Dependent Claim
74 words
