KYOCERA Exhibits Multilayer Ceramic Substrate for Automotive ECU

12. Juni 2006

Kyocera Corporation (headquarters: Kyoto, president: Makoto Kawamura) 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.

A wide variety of Kyocera’s electronic components are also mounted on the ECU for the automatic transmission mentioned above. In addition, the components assemblies are carried out by Kyocera.

From this sense, the ECU is heart of Kyocera’s material, substrates, components and assembly technologies.


Kyocera Corporation (NYSE: KYO,, a global company, was founded in 1959 as a producer of advanced ceramics. By combining engineered ceramic materials with metals and plastics, and integrating them with other technologies, Kyocera has become a leading supplier of semiconductor packages, electronic components, industrial ceramics, telecommunications equipment, optical instruments, laser printers, copiers and solar energy systems. During the year ended March 31, 2006, Kyocera's consolidated net sales totaled approximately JP\ 1,181,489 million with net income of approximately JP\ 69,696 million.
