Abstract
External electrical connectors that interface with the jet engine cabling are required to be electrically conductive for EMI and lightning requirements. The DC resistance between these connectors and their mounting surfaces must be less than 2.5 milliohms. Electronic control systems have experienced difficulty in meeting this bonding specification after environmental stress screening. The particular interface in question is between stainless steel MIL-STD-38999 connectors and chromate conversion (Alodine) coated aluminum. To improve the electrical bonding the addition of nickel plating on the aluminum plate and the connector has been evaluated. The configurations were evaluated in thermal cycling, humidity and salt spray. Bonding resistance versus normal force was determined for the various configurations. The results show that electroplated nickel stainless steel connectors will meet the connector to engine control bonding resistance specification of 2.5 milliohms.
