A multilayer printed circuit board comprising conducting layers of a first material and conducting layers of a second material includes noncorrosive low resistance electrical contacts between conducting layers of the first and second material. The noncorrosive low resistance contacts allow the use of light weight conducting materials for particular layers of the circuit board to produce a light weight multilayer circuit board.
