Abstract
Abstract A modular mounting apparatus for substrate means bearing planar circuit means is provided and includes a design of components that assemble into a housing package for microcircuit modules with means for locating, supporting, interconnecting and housing them; in an interference free environment, i.e., provisions for moisture, radio frequency interference and electromagnetic interference sealing are provided. The apparatus provides a modular systematic and economical means of packaging for low frequency printed circuit boards to microwave frequency microcircuits.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A modular package in which planar circuit means are mounted, comprising: housing means having side walls and a bottom defining a channel-shaped configuration and having a predetermined variable length; elastomeric conduction means in engagement with said bottom and extending substantially along the length thereof; substrate means containing planar circuit means on at least the upper surface means thereof and ground circuit means provided on the bottom surface thereof, said ground circuit means electrically engaging said elastomeric conduction means; removable substrate securing means extending between said housing means and said substrate means urging said ground circuit means into electrical connection with said elastomeric conduction means and said elastomeric conduction means providing cushion means therefor; removable connection means provided by said housing means electrically connected respectively to said planar circuit means on said upper surface means and to said ground circuit means on said lower surface means; and means sealing said substrate means so as to be free from interfering signals.
Claim 2
Dependent Claim
159 words
A modular package in which planar circuit means are mounted, comprising: housing means having side walls and a bottom defining a channel-shaped configuration and having a predetermined variable length; elastomeric conduction means in engagement with said bottom and extending substantially along the length thereof; substrate means containing planar circuit means on at least the upper surface means thereof and ground circuit means provided on the bottom surface thereof, said ground circuit means electrically engaging said elastomeric conduction means; removable substrate securing means extending between said housing means and said substrate means urging said ground circuit means into electrical connection with said elastomeric conduction means and said elastomeric conduction means providing cushion means therefor; removable connection means provided by said housing means electrically connected respectively to said planar circuit means on said upper surface means and to said ground circuit means on said lower surface means; and means sealing said substrate means so as to be free from interfering signals.
Claim 3
Dependent Claim
26 words
The apparatus according to claim 1 further comprising: removable isolation means disposed along the length of said housing means permitting a plurality of said substrate means.
Claim 4
Dependent Claim
27 words
The apparatus according to claim 1 wherein said removable connection means are connected to said planar circuit means and located in end means of said housing means.
Claim 5
Dependent Claim
25 words
The apparatus according to claim 3 wherein said removable connection means are located in at least one of said side walls of said housing means.
