Manufacturing Methods and Technology Engineering (MM and TE) Program for the Establishment of Production Techniques for High Density Thick Film Circuits Used in Crystal Oscillators.

Abstract : Production techniques are being established for a thick film hybrid microelectronic 17-22 MHz, temperature-compensated, voltage-controlled crystal oscillator. The program requirements, the plan for meeting those requirements, the technical approach being pursued and the technical work that has been accomplished are described. The program is subdivided into an engineering phase and a production phase. The engineering phase was started, with the following being accomplished during this reporting period: the configuration design of the TCVCXO module, the detailed layout design of the hybrid microcircuitry used in the TCVCXO module, the detailed design of piece-parts to be used in hermetically sealing the hybrid microcircuits and encapsulating the modules, the breadboard analysis of the TCVCXO electrical design, the establishment of process flow plans for producing the modules, and the selection and procurement of component parts and materials for the construction of the TCVCXO modules. Details of this work are reported. (Author)
