Publication number: 20160157336Abstract: First and second semiconductor devices and first and second bypass circuits are mounted on a printed wiring board. The first bypass circuit and the second bypass circuit are provided closer to the first semiconductor device and to the second semiconductor device, respectively. The first bypass circuit has one end connected to a power plane through a first power supply via and the other end connected to a ground plane through a first ground via. The second bypass circuit has one end connected to the power plane through a second power supply via and the other end connected to the ground plane through a second ground via. The ground plane has a slit between the connecting portions of the first and second ground vias to increase the impedance between the connecting portions of the first and the second ground vias. Thus, jitters caused by power supply noise can be reduced.Type: ApplicationFiled: November 18, 2015Publication date: June 2, 2016Inventors: Yusuke Murai, Shoji Matsumoto, Takashi Numagi, Hiroyuki Yamaguchi, Nobuaki Yamashita

Patent number: 9192044Abstract: First and second signal wiring patterns are formed in a first conductor layer. A first electrode pad electrically connected to the first signal wiring pattern through a first via and a second electrode pad electrically connected to the second signal wiring pattern through a second via are formed in a second conductor layer as a surface layer. A third conductor layer is disposed between the first conductor layer and the second conductor layer with an insulator interposed between those conductor layers. A first pad electrically connected to the first via is formed in the third conductor layer. The first pad includes an opposed portion which overlaps the second electrode pad as viewed in a direction perpendicular to the surface of a printed board and which is opposed to the second electrode pad through intermediation of the insulator. This enables reduction of crosstalk noise caused between the signal wirings.Type: GrantFiled: April 12, 2013Date of Patent: November 17, 2015Assignee: CANON KABUSHIKI KAISHAInventors: Seiji Hayashi, Takuya Kondo, Shoji Matsumoto

Publication number: 20150305149Abstract: A printed circuit board has a printed wiring board and a semiconductor package mounted on the printed wiring board. The printed wiring board and the semiconductor package are connected with a plurality of solder balls. An underfill material covering the plurality of solder balls is filled between the printed wiring board and the semiconductor package.
