A circuit substrate includes an outer plated through hole structure and an inner plated through hole structure located within the outer plated through hole structure. In one example, the circuit substrate includes a core and an outer plated through hole structure having a first metal layer configured over the core to form an outer plated through hole. The circuit substrate also includes an inner plated through hole structure located within the outer plated through hole structure having a second metal layer positioned inside of the outer plated through hole with an insulation layer interposed between the first and second metal layers. Methods for making such a circuit substrate are also described.
