摘要:
An electronic device for an automobile is roughly divided into individual parts and control circuit elements which are mounted in a casing divided into two compartments, according to the present invention. The individual parts are arranged in one compartment and are covered with silicone rubber to improve their water resistance. The control circuit elements are arranged in the other compartment and are covered with a silicone gel to prevent any stresses acting upon the control circuit elements, such as ICs, and provide these elements with moisture resistance. The control circuit elements are bonded by high-temperature solder to improve their heat resistance, but the individual parts are bonded by eutectic solder.
