PROBLEM TO BE SOLVED: To provide a printed wiring board wherein an influence on circuit characteristic can be easily removed by terminal-forming wirings connected to a signal wiring or the like because connecting terminals of a card edge connector type printed wiring board are formed by electrolytic plating. SOLUTION: The printed circuit board of a card edge connector is provided with a plurality of connecting terminals 50, 60 and 70 formed at one end of a substrate 10 by electrolytic plating, and it includes interconnections 20, 30 and 40 which are formed on the surface of the substrate 10 and are electrically coupled to the respective connecting terminals and connecting terminal-forming wirings 100 being respectively in connection with the interconnections when the connecting terminals are formed by the electrolytic plating. The interconnections 20, 30 and 40 are electrically isolated from the connecting terminal-forming wirings 100 by process holes Mh. Thus, an influence of the terminal forming wirings on circuit characterisitic can be easily removed. COPYRIGHT: (C)2007,JPO&INPIT |
