Experienced power developers know that EMI suppression in the PCB design process can save a lot of time for EMI suppression design in the final process to the greatest extent. This article will explain to you the specification steps in PCB EMI design, int
in order to inhibit the crosstalk between PCB circuit board wires, in the design of wiring should be as far as possible to avoid long distance equal wiring, as far as possible to open the distance between lines, signal line and ground and power line as fa
Frame production is the production of PCB circuit board in the early stage, frame design not only has an impact on the uniformity of electroplating, but also has an impact on the milling board,
Wiring is the most important process in PCB design. This will directly affect the performance of PCB board. In the process of PCB design, wiring generally has such three levels of division: the first is the cloth, the most basic requirements of PCB design
High speed digital circuit analysis generally only deals with multilayer PCB with complete plane layer. 2D field extraction analysis is used to consider only signal reflux in adjacent planes, and the hole is only treated as R-L-C of a lumped parameter.
Specific steps :1. Clean and fix the PCB circuit board. 2. Tin the pad on the edge of the IC pin drawing side. 3. Fix the PCB design position. 4. Check whether the pin position is correct
The key to the success or failure of RF circuit PCB design is how to reduce the circuit radiation, so as to improve the anti-interference ability, but in the actual layout and routing of some problems are in conflict with each other, so how to find a comp
In high-speed PCB, with the increase of the transmission frequency of signal, the capacitive impedance between wires decreases and the inductive impedance on the wires increases, and the signal wire will no longer be presented as pure resistance, that is,
The parameters of PCB board layer, signal line spacing, electrical characteristics of driver end and receiver end, and baseline end mode all have certain influence on crosstalk.
In terms of land concessions, tax incentives, free recruitment and other aspects, the enterprises in the east have a great attraction, and the "flowering" momentum of PCB industry in the west appears.
For the signal transmission between the integrated blocks on a printed circuit board, the situation of Td Trd should be avoided. The larger the printed circuit board, the less fast the system speed
