Abstract
Abstract A packaging system for a standard electronic module is provided utilizing a multi-layer, low temperature, co-fired ceramic motherboard. Device packages, such as an RF device package, are formed of low temperature, low dielectric, co-fired ceramic materials. The device packages are mounted on a composite heat sink provide on one side of the motherboard. A pressure plate provide on the opposite side of the motherboard is fastened to the heat sink to compress the device package. Pressure contact interconnects are used to make contacts between the device packages and the particular conductor layer in the multilayer motherboard. The radio frequency conductor layer in the motherboard is isolated from power and control layers by ground planes provided in the motherboard.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
A packaging system for a standard electronic module comprising: a. a low temperature, co-fired ceramic motherboard, said motherboard provided with a plurality of wells, said motherboard having multiple layers provided therein, at least one of said layers containing a radio frequency conductor, said radio frequency conductor being isolated from other layers by ground planes; b. a radio frequency device package, said radio frequency device package fitting into one of said plurality of wells provided in said motherboard, said radio frequency device package being formed of a low temperature co-fired ceramic dielectric material; c. at least one pressure contact interconnect in contact with said radio frequency device package which connects said radio frequency device package to a conductor provided in said motherboard; d. a composite heat sink provided along a first face of said motherboard, said radio frequency device package being mounted on said composite heat sink; and e. at least one pressure plate provided along a second face of said motherboard opposite said heat sink, said pressure plate being fastened to said heat sink to compress the standard electronic module and to force said at least one pressure contact interconnect into contact position.
Claim 2
Dependent Claim
193 words
A packaging system for a standard electronic module comprising: a. a low temperature, co-fired ceramic motherboard, said motherboard provided with a plurality of wells, said motherboard having multiple layers provided therein, at least one of said layers containing a radio frequency conductor, said radio frequency conductor being isolated from other layers by ground planes; b. a radio frequency device package, said radio frequency device package fitting into one of said plurality of wells provided in said motherboard, said radio frequency device package being formed of a low temperature co-fired ceramic dielectric material; c. at least one pressure contact interconnect in contact with said radio frequency device package which connects said radio frequency device package to a conductor provided in said motherboard; d. a composite heat sink provided along a first face of said motherboard, said radio frequency device package being mounted on said composite heat sink; and e. at least one pressure plate provided along a second face of said motherboard opposite said heat sink, said pressure plate being fastened to said heat sink to compress the standard electronic module and to force said at least one pressure contact interconnect into contact position.
