Electronic component burning jig

摘要

An electronic component burning jig comprising a base ( 11 ) and a zirconia layer ( 12 ) with which the surface of the base is characterized in that the zirconia layer containing one or more metal oxides forming a liquid phase is fired and the liquid phase ( 15 ) is crystallized after the firing to improve the separation resistance and wear resistance. Even when the zirconia layer is formed by a low-cost method such as coating, the zirconia layer is not separated from the base and no particle comes off the zirconia layer.
