Patent number: 10559534Abstract: A circuit substrate includes a dielectric layer, a first conductive structure and a second conductive structure. The first conductive structure includes a first conductive circuit and a first conductive via. The first conductive circuit is disposed on the dielectric layer. The first conductive via is disposed in the dielectric layer, and the first conductive circuit is connected to the first conductive via. The second conductive structure includes a second conductive circuit and a second conductive via. The second conductive circuit is disposed in the dielectric layer, the second conductive circuit and the first conductive circuit of the first conductive structure are arranged with an interval, and the second conductive via surrounds the first conductive via with an interval. The second conductive structure has an extending portion. The extending portion protrudes toward the first conductive via and does not contact the first conductive via.Type: GrantFiled: August 2, 2018Date of Patent: February 11, 2020Assignees: Industrial Technology Research Institute, First Hi-tec Enterprise Co., Ltd., NEXCOM International Co., Ltd.Inventors: Sheng-Che Hung, Min-Lin Lee, Ching-Shan Chang, Hung-I Liu

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

Publication number: 20030046468Abstract: A high-density system includes a plurality of system units. Each system unit includes a backplane and a plurality of central processing unit (CPU) cards plugged into the backplane. Each backplane has a servicing input/output (I/O) bus for carrying servicing I/O data. Each central processing unit (CPU) card is plugged into the corresponding backplane and capable of accepting data from the servicing I/O bus or sending data to the servicing I/O bus. The high-density system further includes at least one cable for connecting the servicing I/O busses of the system units so as to transfer the servicing I/O data, and a servicing control system. The servicing control system includes a switching system for selectively connecting only one of the CPU cards in the high-density system to the servicing I/O bus, and an I/O interface module electrically connected to the servicing I/O bus. The I/O interface module has at least a port to which an external device may be plugged.Type: ApplicationFiled: August 30, 2001Publication date: March 6, 2003Inventors: Hsiang-Chan Chen, Hung-I Liu
