Material Design of High Heat Resistant Resin Based on Bismaleimide

Abstract

In recent years, the electronically controlled automobiles such as electric and hybrid cars are increasing. ECU (Electronic Control Unit) installed in electric and hybrid cars is placed in more severe temperature environment such as installing the ECU directly on an engine, or integration of an electric machine integrating engine and electronic components, in the future. Therefore, the packaging materials for automobile used for the ECU is required to have the performance that can be mounted on severe temperature environment. One of the required performances is long-term heat resistance at 200℃ or higher. In this paper, the author’s studies are introduced on the modification method of bismaleimide resin, which is attracting attention as a highly heat resistant resin exceeding epoxy resin, which is mainly used as a resin for packaging materials.
