Abstract
A circuit board includes a baseboard, a first conductive circuit layer, a second conductive circuit layer, at least one through hole, and a number of conductive lines. The first conductive circuit layer includes a number of first conductive circuit lines formed on a first side of the baseboard. The second conductive circuit layer includes a number of second conductive circuit lines formed on a second side of the baseboard. The through hole is defined through the first conductive circuit layer, the baseboard, and the second conductive circuit layer. The number of conductive lines are formed in an inner wall of the through hole and spaced apart around the through hole. Each conductive line electrically couples one of the first conductive circuit lines to a corresponding one of the second conductive circuit lines.
