High-frequency induction heating for tiny foreign metals

Abstract

The anxiety of tiny metal contamination into resin materials in the manufacturing process has become one of the serious issues. Because it may often cause of overheat in lithium-ion batteries, flat panel displays, and so on. Therefore, a study on detecting method of the tiny metals is a significant issue. The authors have been investigating the high-frequency induction heating (IH) based approach for tiny metals detection. In this paper, effective magnetic circuit design and IH conditions are discussed and demonstrated from theoretical and experimental point of view.
