In high-speed PCB design, the serpentine line has no so-called filtering or anti-interference ability, which can only reduce the signal quality, so it is only used for timing matching and has no other purpose.
Separate the low level analog circuit from the digital circuit to avoid the common impedance coupling between the analog circuit, the digital circuit and the common circuit of the power supply.
Radio frequency and microwave signals are very sensitive to noise-much more so than ultra-fast digital signals. This means that you need to work hard to keep noise, ringing, and reflection to a minimum, while carefully handling the overall system
Power layer copper is a faster and easier option for most PCB design software. By sharing a large number of wires, maximum efficient current with minimum impedance or voltage drop is guaranteed, while providing an adequate grounding return path.
With the growth of screen printing skills, screen printing skills occupy more and more important positions in the printed circuit manufacturing industry, its application, not only improved the production of printed circuit obedience, low production cost o
SMT in the production process of PCB design requirements,In SMT patch processing technology, there are certain requirements for PCB design. Here, Pate Technology gives you an example.
The coupling capacitance between the wires determines the amplitude of the forward crosstalk pulse, and the coupling capacitance is determined by many factors, such as PCB material, geometry, line crossing location, and so on.
Flexible Printed Circuit (PCB) can be designed with the general design of PCB software. Also use Gerber format for FPC manufacturers. Because the manufacturing process is different from ordinary PCBS, each manufacturer will have their own limits on minimu

Coupled with these miniaturized PCB design rules, the problem of crosstalk noise becomes more and more acute, and the problems of crosstalk, switching noise, and ground bounce are exacerbated by the ball-grid arrays and other high-density packages themsel
Protel is the most convenient to use, the fastest to operate, the best humanized interface auxiliary tool in the circuit aided design (EDA) industry at present, and also the most used EDA tool in China. This paper takes Protel99 SE as a design tool to ana
Given that most of the circuit boards designed by engineers are traditional printed circuit boards with a thickness of 62mil and no blind or buried holes, the discussion of layering and stacking of circuit boards is limited here.
