Wiring rules for high speed PCB boards with four or more layers.PCB version is divided into many layers, which high four layers of wiring skills, the following for you to introduce, I hope to help you.
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
Digital circuit and analog circuit isolation. It is a general principle in all PCB designs to keep digital circuits as far away from analog circuits as possible, and it applies to RF PCB designs as well.
The relevant design elements constituting the PCB shall be described in the design drawing. Appearance should be represented by Mechanical 1 layer (priority) or Keep out layer.
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
With these tools, problems can be detected before the ENIG board is used, avoiding the creation of a large number of board components with reliability problems and keeping losses to a minimum.
ENIG surface treatment circuit board is one of the biggest advantages of the circuit board production and manufacturing process is simple, in principle only need to use two kinds of chemical potion (electroless nickel plating and acid gold water) can be c
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
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
Product quality improvement Due to the small size and strong function of chip integrated circuit, one chip integrated circuit can realize the functions of several THT circuits on the SMT circuit board, so the probability of failure of the circuit board is
In the high frequency electronic circuit, to prevent electromagnetic radiation is always the concern of designers, the use of metal patch can act as a shield plate, play the role of shielding electromagnetic.
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.
