Abstract
A circuit card assembly includes a substrate having longitudinally spaced first and second substrate end edges and transversely spaced top and bottom substrate surfaces. The top and/or bottom substrate surface has first, second, and third substrate regions. The first substrate region is directly laterally adjacent the first substrate side edge. The third substrate region is directly laterally adjacent the second substrate side edge. The second substrate region is located between the first and third substrate regions. At least one circuit trace is located on the selected substrate surface. The portion of the circuit trace in the first substrate region is made of only a first material. The portion of the circuit trace in the third substrate region is made of only a second material. The portion of the circuit trace in the second substrate region is made of both the first and second materials.
