| 摘要 |
A printed circuit board according to the present invention is a printed circuit board (4) including a component mounting pin (1) made of a metal wire to connect with a semiconductor chip (10). The semiconductor chip (10) is a surface mounting type semiconductor chip having an electrode pad on its mounting surface for use in a flip-chip mounting system. The component mounting pin (1) is formed by using wire-bonding technology. This printed circuit board (4) is able to decrease malconnections or disconnection caused by a difference between the coefficients of thermal expansion of the semiconductor chip (10) and the printed circuit board (4).
