Abstract
The utility model belongs to the field of electronic technology, in particular to a wide-temperature SMD quartz-crystal resonator. The quartz-crystal resonator comprises an upper cover, a base and a wafer, wherein, the wafer is coated with a silver electrode. The utility model is characterized in that the thickness of the wafer is designed to have a gradient variation; and two led-out electrode glue points and an intermediate auxiliary glue point are arranged on the electrode to form a three glue point manner. Since the thickness of the wafer of the utility model is designed to have a gradient variation, the wafer can avoid the generation of the interference within the wide temperature range; and since the damage is generated during the temperature variation or the fall-off of the resonator, the quartz-crystal resonator adopts three glue point manner, and adds the auxiliary glue point to improve the seismic reliability of the SMD quartz-crystal resonator.
Description
Technical field
The utility model belongs to the electronic technology class, specifically is a kind of wide temperature SMD quartz-crystal resonator.
Background technology
Fa Zhan surface mount (SMD) quartz-crystal resonator now, than original direct insertion DIP quartz-crystal resonator, though obtained the effect of chip type, miniaturization, but owing to reducing of inner space, its temperature and antidetonation reliability descend to some extent, keep its temperature characterisitic in wider temperature range, keep normal steady operation, currently also need some technological improvements.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provide a kind of rational in infrastructure, make the wide temperature SMD quartz-crystal resonator simple, that volume is less, the temperature frequency reliability is higher.
Technical solutions of the utility model are as follows:
A kind of wide temperature SMD quartz-crystal resonator of the utility model, comprise loam cake, pedestal, wafer, the silver electrode that is covered on the wafer, it is characterized in that: chip design becomes thickness that graded is arranged, and two extraction electrode glue points and middle auxiliary glue point formation three glue point types are arranged on the electrode.
The Thickness Design of the utility model wafer becomes graded to be arranged, the generation that wafer can be avoided interference in wide temperature range; Owing to be damaged when variations in temperature or resonator fall, this product adopts bikini point glue, has increased auxiliary glue point, and the antidetonation reliability of SMD quartz-crystal resonator is improved.
