Kyocera Corporation has developed a multilayer ceramic substrate for use in an Electronic Control Unit (ECU) on the most advanced automatic transmission produced by Aisin AW Co., Ltd. An exhibit of the substrate attracted an enthusiastic audience at the Automotive Engineering Exposition 2006 hosted by the Society of Automotive Engineers of Japan (JSAE), held May 24 - 26 at the "Pacifico Yokohama" in Yokohama-city, Japan.
The Aisin AW transmission is a High Torque Capacity FWD (Front Wheel Drive) 6-speed with the ECU mounted directly onto the transmission. Mounting the ECU directly to the transmission requires harsh environmental durability due to high temperature and high vibration exposure, where high reliability and a small size module substrate are essential.
Kyocera developed the multilayer ceramic substrate for this application based on unique material technologies and process technologies for size reduction, high density and high precision substrates. Direct mounting of ECU on Transmissions and Engines are increasing in popularity and growing rapidly for these types of applications, according to Kyocera.
The automotive market is an important strategic market for Kyocera, which is well positioned to support a variety of product lines including ceramic materials, substrates, packages, electronic components, structural products and cutting tools, all found deployed in the vast opportunities of the automotive market.
