Multi-layer Ceramic Substrates for ECU
Kyocera ECU substrates provide high density circuit design, high temperature durability, good heat dissipation and high reliability with multilayer ceramics. HTCC (High Temperature Co-fired Ceramics, alumina system), and LTCC (Low Temperature Co-fired Ceramics, glass ceramic system) are available. Printed resistors and high-current-capacity "Trough" conductive line structures are also available.

 Product Outline
Features
· 100 micron via, line width and pattern gap possible for high density design
· High temperature durability suitable for "In-Transmission" harsh environments
· Ceramic’s high thermal conductivity provides excellent heat dissipation
· Thermal expansion matching allows high reliability in bare-chip assembly to the board
· Available with printed resistors on the back side of the substrate
· High-current-capacity "Trough" conductive line structures are available

Applications
· ECUs for fuel injection
· ECUs for automatic transmissions
· ECUs for electronic power steering
· ECUs for starters/alternators
· DC-DC converters
