Film Electronics Pvt. Ltd. Manufactures Thick Film Hybrid Microcircuits. Film Electronics Pvt. Ltd. Also manufactures a range of thick film hybrid microcircuits. The fabrication of thick film hybrid microcircuits is done by the screen printing of conductive, dielectric and resistive pastes on to 96% alumina substrates. These pastes, when fired at temperatures in the range of 800øc to 1000øc, become an integral part of the substrate and form the basic structure of the hybrid microcircuit. Out of tolerance resistors can be trimmed to desired values up to 1% accuracy or more, by using air abrasive / laser technique. Functional trimming is utilized where circuit function is of prime importance compared to specific value of resistance and tolerance. Discrete components, both active and passive, are added to the substrate with the generated basic structure to complete the circuit, and finally hermetically sealed into customer desired packages.
