Claim 6:
7. A conductive structure comprising:
a substrate having a first surface and an opposite second surface;
an inter-surface junction having an air gap formed in the substrate, the air gap enabling access between the first surface and the second surface;
a pair of first complementary conductive traces arranged on the first surface of the substrate, each comprising a linear portion and a terminal portion,
wherein the terminal portions of the pair of first complementary conductive traces comprise a pair of circular arc profiles with a pair of complementary notches facing toward the air gap; and

a pair of second complementary conductive traces arranged on the second surface of the substrate, each comprising a linear portion and a terminal portion,
wherein the terminal portions of the pair of second complementary conductive traces comprise a pair of circular arc profile with a pair of complementary notches facing toward the air gap;

a dielectric region, wherein the terminal portions of the pair of first complementary conductive trances are arranged in the dielectric region,
wherein the pair of first complementary conductive traces, the pair of second complementary conductive traces, and the dielectric region are exposed from a solder mask layer disposed over the substrate.
