Problems solved by technology

[0004] 1. High cost: It is necessary to process three-lead wires with nail heads, make spot welding equipment, and three-lead bending equipment; at the same time, there is a problem of welding defect rate
[0005] 2. Low efficiency: The processing technology is complex, requiring three-lead processing, importing, spot welding, bending and other processes, and the processing of a single quartz crystal resonator, the labor efficiency is too low
[0006] 3. The directionality of the third lead of the quartz crystal resonator is uncertain: it is necessary to make two ground pads on the circuit board or manually place the direction of the third lead of the resonator in the same direction
[0008] 5. The product stress change caused by bending the third lead affects the frequency of the resonator

Abstract

The invention belongs to the field of an electronic component, and particularly relates to a surface false-patch quartz crystal resonator having a grounding welding spot and a processing method thereof. The surface false-patch quartz crystal resonator related by the invention comprises a quartz crystal resonator, and an insulating spacer, wherein the insulating spacer is sleeved on a quartz crystal resonator bottom plate; the insulating spacer forms an exposed area on the bottom plate of the quartz crystal resonator; and the grounding welding spot is formed in the exposed area. The processing method in the invention comprises the steps of forming the exposed area at a position, where needs to be formed into a grounding point, of the surface false-patch quartz crystal resonator, directly enabling a welding material to contact the exposed area, and forming the grounding welding spot on the bottom plate of the surface false-patch quartz crystal resonator via a hot melting process. According to the surface false-patch quartz crystal resonator having the grounding welding spot and the processing method thereof related by the invention, the insulating spacer and the hot melting process are adopted to process the surface false-patch quartz crystal resonator, and a metal welding spot is formed on the exposed part of the surface false-patch quartz crystal resonator bottom plate, so the function of a third lead in the traditional process is substituted.
