Embodiment Construction

[0029] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0030] For piezoelectric crystal oscillating components, having a highly stable electrode structure is directly related to the reliability of its components. For example, using piezoelectric crystal oscillating components with high thermal stability electrode materials can ensure that the piezoelectric crystal oscillating components are In a relatively high temperature operating environment, it can still maintain excellent electrical characteristics and stable frequency output. Therefore, the present invention discloses an electrode of a piezoelectric crystal oscillating element, so that the piezoelectric crystal oscillating element can have a more stable frequency control capability.

[0031] FIG. 1 and FIG. 2 are respectively a schematic view of the electrode structure and an exploded view of the ele...
