Firing jig for electronic element

摘要

This invention provides a firing jig for an electronic element comprising a spray coating layer made of a material less reactive to a material to be fired on a substrate made of a ceramic, wherein two or more spray coating layers are formed on the surface of the substrate, and at least a spray coating layer adjacent to the substrate and a spray coating layer adjacent to the material to be fired are made of different materials. When it is a firing jig for an electronic element comprising a ceramic substrate, a surface adjacent to the substrate is a spray coating layer and the surface of the spray coating layer is a flame coating layer. The firing jig for an electronic element has a longer life and can be produced with a lower cost.
