Abstract
The utility model relates to a glass package crystal oscillation, comprising a ceramic base and a ceramic upper cover. Inner part of the base is built in a crystal chip plated with silver electrode. The chip is adhered to the inner electrode of the base by a conductive adhesion. The inner electrode line is connected with the outer electrode of the base, sealing the base and the upper cover by glass adhesion. Volume of the crystal oscillation is 3.2mm * 2.5mm * 0.8mm. An inclined angle formed by the glass adhesion and the ceramic upper cover is more than 100 degrees. The utility model uses the glass package to substitute the metal package, which reduces size of the ceramic base and the cover, reduces cost of the materials to a great extent and realizes a quartz crystal oscillator with low cost, small volume and high frequency accuracy. The glass adhesion is changed from a vertical form to an inclined form, which ensures sealing property of the oscillator and structural strength well.
Description
Technical field
The utility model belongs to electronic technology field, particularly relates to a kind of glass packaging crystal oscillator of microminiaturized quartz crystal.
Background technology
Along with the quick growth of consumption electronic products (as mobile phone, digital camera etc.), the demand of light, thin, short, little crystal oscillator is become the market mainstream, thereby miniaturization crystal oscillator demand increases rapidly; Though the volume of metallic packaging crystal oscillator is less, its price is comparatively expensive.It is little to develop a kind of volume, and the encapsulation crystal oscillator that cost is low has broad prospects.
Summary of the invention
Technical problem to be solved in the utility model provides the glass packaging pottery quartz-crystal resonator that a kind of dimensional structure gives miniaturization, satisfy the application demand in consumption electronic products market, but in the miniaturization process, encapsulation technology is the difficult problem on it is produced, by the improvement on the encapsulating material size, this problem is overcome.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of glass packaging crystal oscillator is provided, comprise base of ceramic and ceramic loam cake, base interior is inserted the crystal chip that plates the band silver electrode, adopt conducting resinl that chip is adhered on the base interior electrode, the internal electrode circuit connects the pedestal outer electrode, stick together with glass pedestal and loam cake are carried out involution, described crystal oscillator volume is 3.2 * 2.5 * 0.8mm.
Described glass sticks together the oblique angle that becomes with ceramic loam cake greater than 100 degree.
Beneficial effect
1. the size of miniaturization glass packaging crystal oscillator: make volume narrow down to 3.2*2.5*0.8mm by 5.0*3.2*1.2mm, close with metallic packaging crystal oscillator volume (3.2*2.5*0.7mm), use the encapsulation of glass packaging substituted metal, dwindle base of ceramic and capping size, significantly reduce material cost, realize the quartz-crystal resonator of low cost, small size, high freuqency accuracy.
2. the technology of glass packaging mode: glass sticks together by vertical in form and changes the inclination form into, guarantees the resonator good sealing property, and structural strength.
