Description

The crystal resonator substrate

Technical field

The utility model relates to a kind of quartz-crystal resonator raw material, particularly belongs to a kind of quartz-crystal resonator substrate.

Background technology

Based on the rapid update of product in the electron trade, electronic devices and components are just day by day towards miniaturization, microminiaturized future development.But there is the problem of two aspects in prior art: one because quartz-crystal resonator substrate volume is larger, thereby has caused product integral body can't realize miniaturization and microminiaturization.On the other hand, if the substrate volume is too small, be processing and the limited space of producing reservation, can increase the difficulty of product when producing and use, cause the difficult quality control of product, production efficiency is difficult to improve, and then can increase the unit cost of production.

The utility model content

The purpose of this utility model is to provide a kind of novel crystal resonator substrate, to reach microminiaturization, the miniaturization that can realize product, can reserve necessary size and space for making to produce again, thereby obtain the maximized purpose of comprehensive benefit.

Crystal resonator substrate provided by the utility model, has body, body top projection is boss, it is protruding that the body edges place is provided with the sealing of being combined with shell, be symmetrically arranged with two insulator placement holes on the boss, it is characterized in that the length of body is the 6.5-8.0 millimeter, wide is 4.0 millimeters of 3.75-; The length of boss is the 5.5-7.0 millimeter, and width is the 2.75-3.0 millimeter; The gross thickness of body is the 0.68-0.75 millimeter; The body bottom surface is the 0.55-0.6 millimeter to the protruding apical side height of sealing; The diameter of two insulator placement holes is the 1.1-1.3 millimeter, and centre-to-centre spacing is the 2.5-4.5 millimeter.

Crystal resonator substrate provided by the utility model in use, fits together with insulator, wire, sinters quartz crystal resonator base into through high temperature furnace.Because the full-size of substrate is limited, supporting raw material size also can correspondingly be dwindled with it, therefore can guarantee microminiaturization, the miniaturization of product integral body, simultaneously, the utility model also limits for the minimum dimension of substrate, reserve requisite space for making processing and follow-up use, carried out with can guaranteeing the production process high efficient and reliable, had reasonable in design, good effect that size is suitable.
