In this report we focus on development of smaller and lighter ECUs for Automatic Trans-Missions (ATM). Specifically, we describe the development of ECUs that utilize: detailed printed wire patterns, bare chip semiconductors with wire bonding technology, and many small Surface Mounting Devices (SMDs), on a metal based board with high heat dissipation. In comparison with our current products, we have achieved: (1) a 58% reduction in size, (2) a 63% reduction in weight, and an extended thermal range of operation. These new ECUs are suited for the severe environment of the engine compartment.
