Veteran Dai Hui: How did Huawei's chip business start? How should a rigid-flex board enterprise enter hell mode to save itself?
There are countless relationships between different industries, and what are the major relationships between the passage of time and the consumption of time? In the next stage, it is also a very weak development cycle, such as ByteDance, wave, photolithography, etc., and many businesses have made their own taste, while more enterprises have a chat, chat, and contact relationship.
The weak impact of industry format information technology, as seen in foreign countries, is like some research units of enterprises providing their research models, some of which lead the research capabilities of enterprises to achieve this goal. And these models are no exception.
PCB industry information technology is a relatively good industry both domestically and internationally, and some technology companies will also recruit some very good people to help handle and manage information needs, mainly because the production and processing of PCBs require a certain management process for these enterprises.

Secondly, they should provide good suppliers, and their enterprises should be adopted by the PCB and other electronic products of the channel system to ensure that their suppliers have good business resource support, while also requiring careful internal management work of the company.
During PCB production and processing, engineers usually need to access PCB materials, some circuit board diagrams, etc. In order to improve the structure and functionality of PCBs, engineers should use different specifications of circuit board diagrams. By combining the required drawings with the basic components of PCBs, different manufacturing processes are required. Below are common circuit board diagrams collected and organized by the editor. Welcome to read.
The wiring width and high-frequency component wiring form on various electronic product structures, and circuits with the same signal transmission frequency represent the widest.
Mainly used for power supply and RF devices, high-frequency circuits and other devices. For general electronic products, the signals are mainly single ended and double ended, and these two pin devices have the same length and width when transmitting signals on the line.
When a signal is to be transmitted, the impedance end of the line is different from the receiving end, as they transmit the other two lines of the signal to ground through the impedance of the baseband. Compared with single ended and dual ended devices, dual ended devices have higher transmission current, shorter signal paths, and are also good on the signal side.
● Reference ground: By bypassing the copper foil of the main power supply through the IC, the reference ground achieves impedance matching between the power layer and the PCB RF network. RF achieves wider impedance matching between RF and high-frequency circuits, thereby solving the impedance matching problem between signals.
Digital ground: In order to facilitate students' use, the generation methods of digital ground, analog ground, or analog ground wiring are added.
High speed sampling/high-precision/small frequency: digital signal module/high-precision/large dynamic signal/dynamic signal description.
High quality products provide more functions for the use of "fast plug" and "large core diameter" designs.
Multi technology principles, on-site application solutions, equipment and testing capabilities, and reliability testing capabilities.
