ABSTRACT:
A mounting adapted to support and provide a two-terminal connection to a flexural mode quartz crystal vibrator having two opposed surfaces with two electrodes disposed on at least one of the opposed surfaces is provided. The mounting includes a non-conductive member having first and second spaced apart conductive surfaces, the non-conductive member having a lesser thermal coefficient of expansion than the quartz crystal vibrator. At least one metallic plate is disposed between one of the conductive surfaces and the quartz crystal vibrator for coupling an electrode to a conductive surface, the metallic plate having a thermal coefficient of expansion less than the quartz crystal vibrator and the mounting member.
