Claim:
1. A circuit structure, comprising: a conductive post having opposite first and second end surfaces; a first conductive pad bonded to the first end surface of the conductive post, wherein the first conductive pad has an asymmetric geometric shape, a length of the first conductive pad is greater than a width of the first conductive pad, and the first conductive pad is less in area than the first end surface of the corresponding conductive post; a second conductive pad bonded to the second end surface of the conductive post, wherein the second conductive pad is less in area than the second end surface of the corresponding conductive post; and an insulating layer encapsulating the conductive post, wherein the insulating layer has opposite first and second sides, the first conductive pad is positioned at the first side of the insulating layer, the second conductive pad is positioned at the second side of the insulating layer, the first side of the insulating layer is flush with a surface of the first conductive pad, and the second side of the insulating layer is flush with a surface of the second conductive pad.
