Abstract

In this paper, the cause of the insulation resistance of molded inductor in low temperature baking is discussed, and the method to improve the insulation resistance is found. It was found that the surface bonding force between the metal soft magnetic powder and the coating layer increased first and then decreased with the increase of temperature, and the coating layer was brittle with the increase of temperature. The results show that the change of the volume change of the coating layer and the change of the surface binding force between the coating layer material in the curing process, and the higher the degree of curing the coating layer is brittle, and the interaction between the two and the coating layer can produce the peeling or even fall off.
