A sculptured stripline interface conductor for providing spaced apart access to the closely spaced conductors of a circuit element. The low impedance and crosstalk of stripline suggests the use thereof in high-frequency applications. In the sculptured stripline interface conductor of the present invention the circuit traces of the buried signal layer are closely spaced in a first section of the stripline interface conductor and spaced further apart in a second section thereof. In the area where the circuit traces are closely spaced, different-shaped rectangular holes are made in the upper and lower ground plane conductors to expose the inner circuit traces. The upper ground plane conductor also has holes in the second section for exposing a pad in the circuit traces. External connection to each conductor of the circuit element is then made to the circuit trace pad through the holes in the upper ground plane conductor. The circuit element is disposed adjacent the rectangular holes and the leads thereof are connected to the inner circuit traces exposed by the rectangular holes.
