摘要
A circuit board and a smart card module and a smart card employing the circuit board are provided. The circuit board includes a substrate and a pad region provided on the substrate. The pad region is configured for mounting an electronic component, and comprises a plurality of pads spaced from each other and traces connected to their respective pads. At least one of the pads has an arc edge. In the present invention, the distance between the pads is easy to be controlled during fabrication, and the stability of the adhesion between the chip and pad region is enhanced.
