Abstract

The utility model relates to a metallic packaging crystal oscillator, which comprises a ceramic base (2) and a metallic upper cover (1), wherein a crystal chip (4) plated with a silver electrode is placed in the ceramic base (2); the chip is stuck on an electrode in the base by a conductive adhesive (5); an internal electrode circuit is connected with an external electrode of the base; and the ceramic base (2) and the metallic upper cover (1) are sealed by a metallic ring (3) arranged on the ceramic base. The size of the ceramic base (2) is 3.2*2.5*0.7mm. With the adoption of the size-reduced ceramic base and the upper cover, the material cost is lowered greatly, thereby realizing a quartz crystal oscillator with low cost, small volume and high frequency and precision.

Description

A kind of metallic packaging crystal oscillator

Technical field

The utility model belongs to electronic technology field, particularly relates to a kind of metallic packaging crystal oscillator of microminiaturization.

Background technology

Along with the quick growth of consumption electronic products (as mobile phone, digital camera etc.), light, thin, short, little demand becomes the market mainstream, thereby miniaturization crystal oscillator demand increases rapidly; And at a low price product is another big demand of this market, and therefore crystal oscillator cheaply also is to need another big key element of overcoming in design.

Summary of the invention

Technical problem to be solved in the utility model provides the present invention and provides a kind of miniaturization, low-cost quartz crystal, satisfies the application demand in consumption electronic products market.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of metallic packaging crystal oscillator is provided, base of ceramic and metal top cover, the inside of described base of ceramic is inserted and is plated band silver electrode crystal chip, with conducting resinl chip is sticked together on the electrode of base interior, the internal electrode circuit links to each other with the pedestal outer electrode, and base of ceramic and metal top cover carry out involution with the becket on the base of ceramic.

Described base of ceramic is of a size of 3.2 * 2.5 * 0.7mm.

Beneficial effect

Miniaturization metallic packaging quartz-crystal resonator: 3.2 * 2.5 * 0.7mm metallic packaging base of ceramic, use the base of ceramic and the loam cake size of dwindling, significantly reduce material cost, realize the quartz-crystal resonator of low cost, small size, high freuqency accuracy.
