IGNITION APPARATUS FOR INTERNAL COMBUSTION ENGINE WITH IMPROVED ELECTRICAL INSULATION PLATE INCLUDING BERYLLIA

摘要

Provided is an ignition apparatus for internal combustion engines with higher reliability for the solder bonding parts. The ignition apparatus is composed of a mold case having an input-output terminal formed on the mold case as a single body, a semiconductor switching device, a control circuit board, and a heat sink. On the heat sink, single or a plurality of laminated structure is used, including the semiconductor switching devices with beryllia as an electric insulation plate.
