MANUFACTURING METHOD OF QUARTZ RESONATOR Russian patent published in 2010 - IPC H03H3/08 

FIELD: radio engineering.

SUBSTANCE: quartz piezoelectric element with exciting film electrodes are placed into flexible clamps of the holder so that exciting film electrodes can form electric contact to flexible clamps, which are connected through quartz holder to external outputs of quartz resonator. In the arrangement area of flexible clamps there applied are electrically insulated additional contact pads of electrode coating; then to them and to electrode coatings protruding from flexible clamps and to electrically conducting structural elements non-protected with lacquer there plated is nickel, with layer of 20-30 mcm thick. Prior to closure of quartz resonator housing, there performed is cleaning of the construction at temperature of 300-500°C, and at residual pressure of 1·10^-5 mm hg, during not less than two hours. The proposed method is especially effective for precision quartz resonators used in the equipment with large service life.

EFFECT: resistance of quartz resonator to increased temperature and to rigid mechanical loads is the effect of the invention.
