PCB design techniques to improve electromagnetic compatibility of circuit boards
In order to suppress the cross talk between the printed 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 lines and ground and power
PCB Stack PCB design principles
PCB stacking PCB design principles. The most efficient way to stack boards is to arrange the main ground (the main ground) in the second layer below the surface, and to arrange RF lines on the surface as much as possible.
Analysis of common problems and design principles in RF integrated circuit PCB design
Under normal circumstances, for the circuit below the microwave frequency band (including low frequency and low frequency digital circuit), careful planning under the premise of a comprehensive grasp of various PCB design principles is the guarantee of on
Embedded PCB design needs to master the basic concept
In order to facilitate the installation and maintenance of the circuit, the required logo pattern and text code are printed on the upper and lower surfaces of the printing board, such as component label and nominal value, component outline shape and manuf
PCB design requirements for circuit board structure design
In general, the direction of wave soldering on the printed circuit board should be parallel to the long side of the printed circuit board and perpendicular to the short side of the printed circuit board.
PCB design process circuit board layout requirements
The two long edges of PCB should be parallel, and the non-parallel edges should be added to facilitate the equipment transmission in the production and processing process.
Component layout requirements in PCB design
The layout of printed circuit boards using automatic plug-in technology should meet the technical requirements of automatic plug-in machines.
Analysis of common problems and solutions in high speed 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.
Radio frequency (RF) circuit PCB design skills
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
PCB design printed wire width should follow the law
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
