Rough surface coated kiln furniture for kilning electronic components

Abstract

The invention belongs to the technical field of kiln furniture, and discloses a rough surface coated kiln furniture for kilning electronic components, which includes a kiln furniture main body, wherein a coating on the upper surface of the kiln furniture is a rough surface coating; the rough surface coating is formed by fuzzily fusing peripheries of uneven thin particles or thin strips forming the rough surface with a peripheral coating; the coating is satisfactorily combined with a base surface, so as to prevent scaling off of the surface. The rough surface coated kiln furniture has high thermal shock resistance.

Description

technical field [0001] The invention belongs to the technical field of kiln furniture, in particular to rough-coated kiln furniture used for firing electronic components. Background technique [0002] Electronic components are the foundation of the electronic information industry and have broad market prospects. The firing requirements of electronic components are relatively high. To ensure the electrical characteristics of electronic components, zirconia setters are generally used. Since zirconia setters are consumables, the price is relatively expensive; currently used kiln furniture generally adopts surface coating. Zirconia or one-piece pressed composite setter plate with zirconia on the outer layer; Chinese patent application number: 200820088727X Nano-zirconia reinforced and toughened composite setter plate is evenly sprayed with 0.3~0.5mm nano-zirconia coating on the surface, and the coating is fired. Form a uniform surface and cover it on the setter board; Applicati...

AI Technical Summary

Problems solved by technology

[0003] The present invention just overcomes the deficiencies of the above-mentioned patents and provides a rough-coated kiln furniture for firing electronic components, which not only solves the problem that the kiln furniture and electronic components affect the characteristics of electronic components during the firing process, but also The upper base coating of kiln furniture is not easy to combine with the base layer of kiln furniture. During the firing process, the thermal shock resistance is poor, the service life is short, and the problem of peeling will occur.
