Publication number: 20150029682Abstract: Proposed is a C/U that is designed to accomplish the above object. The CU includes a multilayer circuit substrate, a resin cover, and a metal base. Electronic parts are mounted on both surfaces of the multilayer circuit substrate which is covered with the resin cover and the metal base. The multilayer circuit substrate 8 includes a signal pattern, a GND pattern, an important signal pattern, and a multilayer circuit substrate insulating layer. The GND pattern is electrically connected to the metal base through a screw. The GND pattern is disposed on the side of the resin cover in order to shield the important signal pattern against electromagnetic waves penetrating the resin cover to enter a housing and electromagnetic waves incident from the metal base side. The important signal pattern is disposed so that it is covered with the GND pattern and the metal case.Type: ApplicationFiled: February 8, 2013Publication date: January 29, 2015Applicant: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Kiyoomi Kadoya, Ryosuke Ishida, Takuya Mayuzumi, Kenichi Hoshino, Yasuhiko Okada, Yasushi Sugiyama
