Challenge: Building control modules for electronic fuel-injection engines

Because today's boat manufacturers favor electronic fuel injection (EFI), Delco Electronics needed a marine engine control module (ECM) that could handle the advanced electronics required by EFI.

Solution: DuPont thick-film conductor and dielectric materials

Delco designed its ECM using thick film hybrid circuit technology because of the proven ability of ceramic materials to handle high power dissipation and perform in high temperature environments with cycling between temperature extremes.

DuPont's thick-film materials, including a 3:1 Ag/Pd conductor and compatible dielectric, allowed Delco to design the ECM to meet specific needs. Because multilayer thick-film designs, reduce package size, the ECM could be more easily mounted directly on the engine. Delco used the DuPont materials to design the ECMs with added protection from corrosion and vibration, heat resistance, and shielding from electro-magnetic interference.

The DuPont materials also provided excellent solderability, adhesion, reliability, and good yields in high-volume production.
