A lead frame for assembling a smart card is formed with a substrate having first and second opposing major surfaces. A die receiving area is formed in the first major surface of the substrate and surrounded by conductive vias. A conductive coating is formed on the second major surface of the substrate and patterned to form electrical contact pads over the conductive vias. A conductive trace is formed on the first major surface of the substrate. The conductive trace extends between at least two adjacent vias and partially surrounds the at least two adjacent conductive vias, thereby forming a gap in the portion of the trace that surrounds the vias. An electrical connection between an integrated circuit chip and the conductive via extends over the gap. The gap prevents the electrical connection from inadvertently contacting the conductive trace.
