Abstract
The utility model provides a novel piece-type glass sealing chassis. The novel piece-type glass sealing chassis comprises a glass sealing chassis plate, wherein a circle of a first ceramic layer is arranged on the edge of the glass sealing chassis, a ceramic metallization carrying table is arranged on the glass sealing chassis plate, a second ceramic layer is arranged on the first ceramic layer, and the width of the second ceramic layer is smaller than that of the first ceramic layer. Product packaging yield is greatly improved. The novel piece-type glass sealing chassis is used, so that bonding strength yield of glass sealing chassis and an upper cover is increased to 99.5%.
Description
Technical field
The utility model relates to the quartz-crystal resonator member, is specifically related to a kind of novel chip glass envelope pedestal.
Background technology
At present, quartz-crystal resonator is called quartz crystal again, is commonly called as crystal oscillator, is to utilize the piezoelectric effect of quartz crystal and the resonant element processed, and it uses with semiconductor device and Resistor-Capacitor Unit, just can constitute quartz oscillator.Quartz oscillator is the oscillator of high accuracy and high stability; Be widely used in all kinds of oscillating circuits such as colour TV, computer, remote controller, and be used for frequency generator in the communication system, reference signal be provided for the data processing equipment clocking with for particular system.On surface-mounted integrated circuit, often can use chip (SMD) quartz-crystal resonator (Surface Mounted Devices surface mount device), this type sheet type quartz crystal resonator generally comprises pedestal, loam cake and quartz crystal.The sheet type quartz crystal resonator is according to different metallic packaging, glass packaging, the epoxy encapsulation of being divided into mode of encapsulating material.Sheet type quartz crystal resonator glass packaging adds the loam cake that scribbles low temperature glass by glass envelope pedestal pressurizes through oven heat, low temperature glass is dissolved again solidify, thereby make glass envelope pedestal and loam cake adhering and sealing.Existing glass envelope pedestal and loam cake adhesive strength yield about 98%, qualification rate also has room for promotion.
Summary of the invention
The technical problem that the utility model solved is to provide a kind of novel chip glass envelope pedestal, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of novel chip glass seals pedestal, comprises glass envelope base plate, it is characterized in that, the edge of said glass envelope base plate is provided with a circle first ceramic layer, and said glass envelope base plate is provided with ceramic metallization lift-launch platform.
As a kind of improvement, said first ceramic layer is provided with second ceramic layer, and the width of said second ceramic layer is less than the width of said first ceramic layer.
Because the width of second ceramic layer is less than the width of said first ceramic layer; Can form step with second ceramic layer, like this, low temperature glass dissolves to solidify again when encapsulation has increased the step side contact area; And can play the effect that stores many She glass, improved the product packaging yield.
Owing to adopted above structure, the utlity model has following beneficial effect:
The utility model has improved the product packaging yield greatly, the chip glass envelope pedestal that uses the utility model to provide, and glass envelope pedestal and loam cake adhesive strength yield bring up to 99.5%.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model plan structure sketch map.
Shown in the figure: 1, glass envelope base plate; 2, first ceramic layer; 3, platform is carried in the porcelain metallization; 4, second ceramic layer.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, a kind of novel chip glass seals pedestal, comprises glass envelope base plate 1, it is characterized in that, the edge of said glass envelope base plate 1 is provided with a circle first ceramic layer 2, and said glass envelope base plate 1 is provided with ceramic metallization lift-launch platform 3.
As a kind of improvement, said first ceramic layer 2 is provided with second ceramic layer 4, and the width of said second ceramic layer 4 is less than the width of said first ceramic layer 2.
Because the width of second ceramic layer 4 is less than the width of said first ceramic layer 2; Can form step with second ceramic layer 4, like this, low temperature glass dissolves to solidify again when encapsulation has increased the step side contact area; And can play the effect that stores many She glass, improved the product packaging yield.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model protection defined by the appended claims and their equivalents defined?
