High Density Strip Line Card Connector

Described is a technique for interconnecting microcircuitry with an elastomer coated rod and a multilayered strip line connector, so that information can be fed to the individual cards while maintaining an integral ground plane.

Shown in the figure is a multiplicity of cards 10, 11, and 12 separated and held in position by rods 15 which are coated with an elastomer 14 and maintained with a fixed separation. Overlying each card is a strip line 13 having a multiplicity of contacts for the wires contained therein. This strip line can be provided with a continuous ground plane.

The elastomer coated rod 15 forces the card contacts on the resilient strip line 13 in contact with suitable and appropriate terminations on the card itself. These strip line card contacts can be interconnected to any level of metallurgy within the strip line 13 by via holes. This technique eliminates the solder normally used to connect the strip line 13 to the cards. Additionally the resilient coated rod 15 gives a spring type contact between a strip line 13 and the related card regardless of topological irregularities in the card itself.

The process further increases package density and the card interconnect density, by eliminating the necessity of internal solder connections.
