Patent number: 8476533Abstract: An exemplary printed circuit board includes a substrate, a differential transmission line, and at least two weld pad pairs. The differential transmission line and the at least two weld pad pairs are disposed on the substrate. The differential transmission line includes two parallel signal conductors disposed on the substrate. Each of the two signal conductors is electrically connected to an edge of one of the weld pads of a respective pair of the at least two weld pad pairs. Thereby, the two signal conductors of the differential transmission line can extend in the same distance anywhere, particularly in the position where the two signal conductors pass the two weld pad pairs. As a result, the coupling performance and the capability of the differential transmission line to resist electromagnetic interference are both enhanced.Type: GrantFiled: September 21, 2011Date of Patent: July 2, 2013Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Fa-Ping Fan

Publication number: 20100101841Abstract: A printed circuit board (PCB) is disclosed. The PCB includes a dielectric layer, a power layer, a ground layer, and an electromagnetic interference reducing layer. The dielectric layer includes a central portion and a periphery portion surrounding the central portion. The dielectric layer defines a number of via holes through the periphery portion. The ground layer is adhered to a surface of the dielectric layer, covering both the central portion and the periphery portion. The power layer and the EMI reducing layer are separately adhered to another surface of the dielectric layer facing away from the conductive ground layer. The conductive power layer covers the central portion. The EMI reducing layer substantially covers the periphery portion and is electrically connected to the ground layer via the via holes.Type: ApplicationFiled: August 7, 2009Publication date: April 29, 2010Applicants: HONG FU JIN PRECISION INDUSTRY(ShenZheng) CO., LTD., HON HAI PRECISION INDUSTRY CO.,LTD.Inventor: FA-PING FAN
