Patent ID: 8184444

Claim:
An electrode pad for mounting an electronic component on a surface of a circuit board, the electrode pad comprising: first and second electrode parts facing each other; and third and fourth electrode parts facing each other, the third and fourth electrode parts being disposed adjacent the first and second electrode parts for forming corners of the electrode pad together with the first and second electrode parts, wherein the first to fourth electrode parts comprise chamfered surfaces, and the chamfered surfaces are cut corners of the first to fourth electrode parts forming the corners of the electrode pad, wherein the electrode pad is directly connected to outer electrodes of the electronic component with a solder, wherein the chamfered surfaces are spaced apart from each other by 50 μm to 250 μm and the outer electrodes of the electronic component are spaced apart from each other by about 100 μm to about 150 μm, and wherein chamfered surfaces of the first electrode part, face, and are parallel to, chamfered surfaces of the third and the fourth electrode parts, and chamfered surfaces of the second electrode part, face, and are parallel to, the chamfered surfaces of the third and fourth electrode parts.
