Development of Small, High Performance Electronics Control Units with Metal Based Printed Circuit Board 961023

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. (1)
    a 58% reduction in size,
  2. (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.
