Abstract

The invention discloses a quartz crystal resonator. The resonator comprises a shell, a base, pins, a spring plate, conductive adhesives, a film-coated electrode and a wafer, wherein the film-coated electrode comprises a base electrode and a trimming electrode connected with the base electrode; and the film-coated electrode is attached to the surface of the wafer and comprises a lower chromium coating, a silver coating and an upper chromium coating, which are arranged from inside to outside in sequence. The invention also discloses a processing method of the quartz crystal resonator. The spurious response characteristic of the quartz crystal resonator can be improved.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a quartz crystal resonator and a processing method thereof. Background technique [0002] Quartz crystal resonator is a piezoelectric device made of piezoelectric quartz (that is, crystal), which not only has highly stable physical and chemical properties, but also has extremely small elastic vibration loss. Compared with other electronic components, piezoelectric quartz crystals also have high frequency stability and high Q value, making them an important component for frequency stabilization and frequency selection. AT-cut quartz crystal currently uses its thickness-shear vibration mode, and its vibration frequency is mainly determined by its thickness. This vibration mode will produce a spurious vibration frequency other than the nominal frequency, which is called a spurious response. For the widely used wireless keyboard and mouse applied to the quartz crystal resonator,...
