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
Production techniques are being established for a thick film hybrid microelectronic 17-22 MHz temperature-compensated, voltage-controlled crystal oscillator. In the engineering phase of this program, the following was accomplished during this quarter: the procurement of microcircuit parts and bonding tools, continued procurement of hermetic sealing parts and materials, further test procedure generation, as well as test fixture fabrication. As part of the 10-lot substrate assembly task, TCFG and VCXO substrates were passively trimmed, assembled, and functionally trimmed. Because many problems developed during substrate assembly, hybrid layout redesigns were undertaken for both hybrids. Details of this work, as well as the problems encountered, are reported and documented.
