<p>PROBLEM TO BE SOLVED: To provide a feeding part of a printed board that can eliminate power noise of an LSI by a space-saving structure. SOLUTION: The feeding part of a printed board 1 is provided with two sets of feed plate 3 for ground and feed plate 2 for power supply that are alternately arranged parallel to each other. A sheet-like dielectric 5 is interposed between the feed plate 3 for ground and the feed plate 2 for power supply, and a capacitor is comprised of the feed plate 3 for ground, dielectric 5 and feed plate 2 for power supply. The feed plates 3 for ground and feed plates 2 for power supply are electrically connected to the printed board 1 through feed inserts 4a, 4b, 4c, and 4d, respectively. Power noises generating through operation of an LSI on the printed board 1 is transmitted via the feed inserts 4a, 4b, 4c, and 4d, and they are bypassed by the capacitor. Thus, the transmission of the noises to harnesses in the following power feeding system is blocked.</p> |
