Abstract
The present invention relates to a porous porous hole functional ceramic setter used for firing ceramics for electronic components such as MLCC, HLCC, Ferrite core, and condencer, and more particularly, to ceramics for electronic components such as MLCC, HLCC, Ferrite core, and condencer. The present invention relates to a porous porous hole functional ceramic set having a porous porous hole formed on a plate to improve the quality and yield of a ceramic product for an electronic component with a uniform temperature distribution when firing at a high temperature, and to increase work efficiency.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceramic breathable porous hole setter used for firing electronic components, and more particularly, for electronic components such as MLCC, HLCC, LTCC, Ferrite core, Condencer, thermistor, Varista, Capacitor, Titanium, and PZT. The present invention relates to a ceramic breathable porous hole set in which a porous porous hole is formed in a ceramic plate to improve the quality and yield of a ceramic product for an electronic component with a uniform temperature distribution and to improve work efficiency when the ceramic is fired at a high temperature.
When firing ceramics for electronic components such as MLCC, HLCC, LTCC, Ferrite core, Condencer, Thermistor, Barastar, Capacitor, Titanium, and PZT in an electric furnace, alumina setters are generally used or high quality electronic components are fired. In this case, a zirconia setter is placed, and then the molded electronic component ceramics are placed on a zirconia setter, and a high temperature is applied in an electric furnace, and the electronic component ceramics are fired while supplying a GAS atmosphere.
Conventional firing method is firing by placing a ceramic for electronic components on alumina setter or zirconia setter, alumina setter or zirconia setter is not breathable because there is no pore and pores Since the thickness is not constant, molded articles arranged between zirconia setters when arranging ceramics for electronic components have problems of warpage and non-sintering in the process of firing by thickness variation of the setters. In addition, there is a problem in that the alumina setter and the zirconia setter must be aligned evenly when arranging the ceramic molded parts for electronic components every time, and the manufacturing cost is increased due to the defective rate for electronic components. .
Conventional ceramic sintering setters for electronic components are used by stacking them in multiple layers as they are on shelf frames or ceramic substrate setters. The loading of a large amount of a to-be-baked body in a setter is made with the space | interval of the setter to load close, and the attempt to shorten a baking time is also examined. Therefore, in such a setter, there exists a strong demand for baking a to-be-baked body to a uniform temperature irrespective of the position where it is mounted to a shelf frame.
However, since the conventional ceramic sintering setter for electronic components has not been considered at all for such a request, there is a problem in that uniform characteristics cannot be obtained for electronic components after firing at the time of firing. Conventional setters have a low thermal conductivity (a thermal conductivity of 6.0 W / mK at 0% porosity) because mullite, one of the main constituents of the gas, has a chemical theoretical molar ratio. In the case of the plastic body loaded on the center portion of the setter where the loading position is located near the middle of the hierarchical direction, the plasticity is insufficient, and thus the desired characteristics may not be obtained.
Conventional ceramic sintering setters for electronic components have ceramic pores formed on the plate, and when firing ceramics for electronic components such as MMLCC, HLCC, LTCC, Ferrite core, Condencer, thermistor, Varista, Capacitor, Titanium, and PZT at high temperature Since ceramics for electronic components are arranged on a ceramic setter and fired in an electric furnace, and heat transfer is not smoothly transferred, there is a problem in that deformation occurs at a high temperature, and the quality and yield of ceramics for electronic components are deteriorated.
SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and has a porous perforated hole formed on the plate instead of alumina sagger or zirconia setter used in the firing process of ceramics for electronic components. The purpose of the present invention is to provide a porous porous hole functional ceramic set having a porous porous hole formed in a plate that improves the workability of the firing process by using a functional ceramic setter and improves the quality and yield of ceramics for electronic components.
The present invention provides a breathable porous hole functional ceramic set having a porous porous hole formed in a plate when firing at a high temperature a ceramic for electronic components such as MLCC, HLCC, LTCC, Ferrite core, Condencer, thermistor, Varasta, Capacitor, Titanium, and PZT. With uniform temperature distribution, it is possible to improve the quality and yield of ceramic products for electronic parts, increase the work efficiency, reduce energy cost, reduce manufacturing cost due to process shortening, and improve the temperature distribution of each part. It is effective to improve the quality of the ceramic for electronic components by making it constant.
