Patent number: 11877385Abstract: A circuit board comprises a substrate with opposite first and second sides. A pair of plated through holes (PTHs) extends along z-axis. A pair of signal traces are made on the first side of the substrate and electrically coupled to the pair of the PTHs respectively to form a differential pair. A ground metal is made on the second side of the substrate, the ground metal has a clearance made therein. The ground metal extends fully overlapping with the full signal traces to eliminate reflection noise caused by a boundary between the clearance and the metal ground.Type: GrantFiled: July 14, 2022Date of Patent: January 16, 2024Assignee: FIRST HI-TEC ENTERPRISE CO., LTD.Inventors: Ching-Shan Chang, Kun-Tao Tang, Tsung-Ting Tsai, Chien-Lin Chen

Publication number: 20230189435Abstract: A circuit board and an electronic package using the same are provided. The circuit board includes a rigid board body, at least one bendable extension portion, connecting members, and shielding members. The rigid board body includes conductive layers and dielectric layers therebetween. The extension portion is connected to a side of the rigid board body and formed by layers of the conductive layers and at least one layer of the dielectric layers extending outside the rigid board body. The connecting members are arranged on a connecting end of the extension portion and electrically connected to a signal layer of the conductive layers. The shielding members are arranged around the corresponding connecting members and electrically connected to a ground layer of the conductive layers. The connecting members and the shielding members protrude from the connecting end. A height of the shielding members is lower than a height of the connecting members.Type: ApplicationFiled: December 29, 2021Publication date: June 15, 2023Applicants: First Hi-tec Enterprise Co.,Ltd., NEXCOM International Co., Ltd., Industrial Technology Research InstituteInventors: Min-Lin Lee, Sheng-Che Hung, Ching-Shan Chang, Ying-Tsuen Liou

Patent number: 10129974Abstract: A multi-layer circuit structure includes a differential transmission line pair and at least one conductive pattern. The differential transmission line pair includes first and second transmission lines disposed side by side. Each of the first and second transmission lines includes first and second segments connected to each other. An spacing between the two first segments is non-fixed, and an spacing between the two second segments is fixed. A first zone is located between the two first segments, a second zone is opposite to the first zone and located outside the first segment of the first transmission line, and a third zone is opposite to the first zone and located outside the first segment of the second transmission line. The conductive pattern is coplanar with the differential transmission line pair and disposed on at least one of the first, second and third zones.Type: GrantFiled: August 24, 2016Date of Patent: November 13, 2018Assignees: Industrial Technology Research Institute, First Hi-tec Enterprise Co., Ltd., NEXCOM International Co., Ltd.Inventors: Chien-Min Hsu, Min-Lin Lee, Huey-Ru Chang, Hung-I Liu, Ching-shan Chang
