Description
Technical field
The invention belongs to ceramic substrate and make the field; Relate to a kind of aluminium oxide ceramic substrate material, especially a kind of Low-Temperature Sintered Alumina Ceramics baseplate material and preparation method thereof and the chip fuse for preparing with this material.
Background technology
Traditional fusible cut-out (claiming again safety fuse) generally is take the protection power source importation as main purpose, and what namely we often saw is such as sheet type fusible cut-out in glass pipe type fusible cut-out and the automobile etc.Along with variation and novelization of electronic product development, fusible cut-out has derived many new purposes, such as the protection of device interior printed board and IC etc., the protection of imput output circuit etc.As the protecting component of electronics, the glass pipe type fusible cut-out is by life-time service and since it have volume large, easily broken, can't realize the shortcoming such as automatization installation, can not satisfy the needs of modern electronic product development.
At present surface mounting fuse protector is mainly in Resins, epoxy substrate or ceramic bases and makes single thin film or thick film metal fusing unit, with polymkeric substance or glass material seal, end electrode applies shape with copper/nickel/tin/lead (95/5) and applies.Because the restriction of manufacturing process, the chip fuse of this class routine in use comes with some shortcomings: arc extinguishing is bad during fusing, to have flashing to burn encapsulated layer phenomenon, fusible cut-out aging etc., and owing to used Resins, epoxy or other polymer materials, so the use temperature of this series products is all lower at present, can't obtain wider use temperature scope.
Abroad the ltcc substrate material choose and preparation technology has obtained a lot of gratifying effects, adding glass is the important measures that realize the LTCC technology, the ratio of ceramic powder is the key factor that determines material physical property and electrical property, for obtaining the substrate of low-k, must select glass and the pottery of low-k, mainly contain pyrex/filler, glass/alumina series, glass/mullite system etc., require weighting material when sintering, can form preferably with glass and infiltrate.
Research and development in recent years are mainly devitrified glass system and glass, Ceramic Composite system two classes, such as Al
