CRYSTAL-OSCILLATING DEVICE AND MANUFACTURING METHOD THEREFOR

摘要

A crystal-oscillating device is disclosed with a reduction in size and a favorable Q value. The crystal-oscillating device includes a first packaging material; a crystal resonator mounted on the first packaging material; joining members that join the first packaging material to the crystal resonator; a first sealing frame for joining the second and third packaging materials, the first packaging material, and the second packaging material; and a second sealing frame for joining the second packaging material and the third packaging material to each other. Preferable, the second packaging material is formed in a frame shape to surround an outer peripheral edge of the crystal resonator, and the second packaging material and a crystal substrate of the crystal resonator are formed from the same crystal substrate.

主权项

1. A crystal-oscillating device comprising:
a first packaging material having a mounting surface; a crystal resonator formed from a crystal substrate and mounted on the mounting surface of the first packaging material by at least one joining member that electrically connects and mechanically joins the first packaging material to the crystal resonator; a second packaging material laminated above the mounting surface of the first packaging material and having a frame shape to surround an outer peripheral edge of the crystal resonator; and a third packaging material laminated above the second packaging material opposite the first packaging material to collectively form a sealing space with the first and second packaging materials to seal the crystal resonator therein, wherein the second packaging material and the crystal substrate of the crystal resonator comprise a same crystal substrate.
