LTCC (Low Temperature Co-fired Ceramic) is the ideal material upon which to create RF and microwave products used in many defence electronics programmes. With careful choice of materials, experienced design engineers can create highly sophisticated products based on our customer's circuit schematics. This technology provides very consistent high frequency performance and can incorporate blind or open cavities to provide die and interconnect surfaces with a high level of co-planarity. Hermetic hybrids are sealed in dry nitrogen and incorporate low out-gassing adhesives and eutectic bonds to maintain high performance over long operating life times. Both gold and aluminium wire bonding completes the circuit interconnect and package connections. Reliability is assured via established design rules, careful element (component) evaluation, 100% environmental screening and extensive process control and product qualification procedures.

Typical applications include:

High Frequency amplifiers
Voltage regulators
DC/DC Converters

Uniquely, C-MAC can offer an integration service for the thick film hybrid microcircuits we produce including:

Military grade PCB Assembly (SnPb and RoHS compliant solder) with flying probe or full functional test
Sub-system assembly and test
Full product assembly (box build)
