TU-752 High-speed PCB digital circuit has high frequency and strong sensitivity of analog circuit. For signal line, high frequency signal line should be far away from sensitive analog circuit device as far as possible. For ground wire, the whole PCB has only one node to the outside world. Therefore, it is necessary to deal with the problem of common ground of digital and analog in PCB, while in the board, digital ground and analog ground are actually separated, and they are not mutually related Connection is only at the interface between PCB and the outside world (such as plug, etc.). There is a little short circuit between digital ground and analog ground, please note that there is only one connection point. Some of them are not grounded on the PCB, which is decided by the system design.
EM-528K High-speed PCB is almost everywhere in our industry. And, as quoted, we always say that, regardless of the final product or implementation, each PCB is high-speed with its IC technology.
TU-943N High-speed PCB -- the development of electronic technology is changing with each passing day. This change mainly comes from the progress of chip technology. With the wide application of deep submicron technology, semiconductor technology is becoming increasingly physical limit. VLSI has become the mainstream of chip design and application.
TU-1300E High-speed PCB -- expedition unified design environment combines FPGA design and PCB design completely, and automatically generates schematic symbols and geometric packaging in PCB design from FPGA design results, which greatly improves the design efficiency of designers.
TU-933 High-speed PCB--with the rapid development of electronic technology, more and more large-scale integrated circuits (LSI) are used. At the same time, the use of deep submicron technology in IC design makes the integration scale of the chip larger.
TU-768 PCB refers to high heat resistance.General Tg plates are above 130 ° C, high Tg is generally more than 170 ° C, and medium Tg is about more than 150 ° C. Generally, Tg≥170 ° C PCB printed board is called high Tg printed board.
