Abstract

The invention relates to a high-vacuum surface-mounted miniature tuning fork quartz crystal resonator and a manufacturing method thereof. The resonator comprises a ceramic base, a miniature tuning fork wafer and a metal cover plate; the ceramic base is formed by sequentially superposing a ceramic bottom plate, a ceramic backing plate, a ceramic ring plate and a kovar alloy ring from bottom to top,wherein the bottom of the ceramic bottom plate is provided with a metal pad, and a left protruding bonding pad and a right protruding bonding pad are arranged on the ceramic backing plate. The resonator is manufactured through a high-vacuum baking degassing process, a sealing nitrogen parallel seam welding process and a high-vacuum laser spot welding process. The manufacturing method is simple and rapid, and the manufactured resonator is reliable in quality, long in service life and excellent in electrical performance.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a high-vacuum surface mounted miniature tuning fork quartz crystal resonator and a manufacturing method thereof. Background technique [0002] With the rapid growth of consumer electronics products (such as digital cameras, mobile phones, e-books, etc.), miniaturization and low-cost products are an important part of occupying the market in order to meet market demand, but low-cost glass packaging is difficult to overcome How to apply the sealing technology under vacuum to the tuning fork type quartz crystal resonator (that is, the glass cannot be sealed in vacuum in the molten state) is a major factor that needs to be overcome in the manufacturing technology. [0003] Chinese Patent Application Publication No. CN102324909A, the invention patent of which the application publication date is January 18, 2012 discloses a glass-encapsulated tuning-fork quartz crystal resona...
