ABSTRACT:
In order to mount a power transistor chip, a multilayered member formed by fixing a molybdenum plate to a copper base is flattened by eliminating its deformation in the member caused by heated fixing through elastic working, it is possible to prevent cracking in a power transistor chip or a solder layer caused by the deformation. Especially, it is possible to improve the reliability of an electronic distributing type ignition device mounted on an engine block formed in a unit of an ignition controller and an ignition coil.
