三明治棚板：是以碳化硅，氧化铝，氧化锆复合成型，经高温烧结而成的一种复合型新产品。

·优点：

　　具有碳化硅优良的热传导性和高温荷重性能，同时氧化铝，氧化锆面层能有效确保棚板在高温使用时不会与产品起反应。适合在各种高性能电子元件烧结窑炉中使用。

·常用规格：（mm）

　　295*295*11  310*310*11   320*320*11   320*150*11  300*300*11

　　注：厚度可按客户要求生产

·碳化硅夹芯板理化指标：

Sandwish Board : It is a new combined product, made by high sintering silicon carbide ,alumina ,zirconia together . 

·Advantage:
It has good thermal conductivity and the heat load functions like silicon carbide. The surface made by aluminum and zirconia will not rise reaction with products .
It is suitable to be used in various kiln stove for high performance electronics component.

·Dimension in common usage (mm ):
295*295*11 310*310*11 320*320*11 320*150*11 300*300*11
Note :The thickness can be produced by customers’ require
