SMD quartz crystal resonator anti-impact structure

Abstract

The invention provides an SMD quartz crystal resonator anti-impact structure, which belongs to the technical field of electronic components, and comprises a tube shell, a buffer wafer and a resonancewafer, wherein a first metal lead and a second metal lead are arranged on a base of the tube shell in parallel; a lower-layer first conductive adhesive point is arranged in the middle of the first metal lead; a lower-layer second conductive adhesive point is arranged in the middle of the second metal lead; the upper surface of the buffer wafer is provided with an upper-layer first conductive adhesive point, an upper-layer second conductive adhesive point, an upper-layer third conductive adhesive point and an upper-layer fourth conductive adhesive point; the first metal lead is communicated with a metallized electrode area of a resonance wafer through the lower-layer first conductive adhesive point, the metallized electrode area of the buffer wafer and the upper-layer first conductive adhesive point; and the second metal lead is communicated with the metalized electrode area of the resonance wafer through the lower-layer second conductive adhesive point, the metalized electrode area ofthe buffer wafer and the upper-layer second conductive adhesive point. Through bonding of the buffer wafer and the conductive adhesive, the impact resistance of the crystal is realized.

Description

technical field [0001] The invention belongs to the technical field of electronic components, and more specifically relates to an anti-shock structure of an SMD quartz crystal resonator. Background technique [0002] The resonant chip in the traditional SMD (Surface Mounted Devices abbreviation, meaning: surface mount device) surface-mounted quartz crystal resonator is supported by two points, and the impact resistance is basically about 2000g. [0003] In order to improve the impact resistance of the quartz crystal resonator, the number of supporting glue points can be increased to four points. If the four glue points are directly connected to the surface-mounted tube shell and the quartz wafer, the impact resistance will be poor due to the difference in expansion coefficient of different materials, resulting in the cracking of the quartz wafer.
