High frequency PCB design: Factors affecting the performance of RF signals
This top view provides an example of installing a row of ground through holes in the top metal ground area on each side of the intermediate conductor. The circuit current caused by the top layer is short-circuited to the ground below.
Printed pcb design success of the seven technologies to be determined
The problem is clear. A technically correct but confusing schematic is still a bad schematic." Although this view is easy to accept, in CAD programs, an unreadable schematic diagram can still describe the circuit connection information, and is still ...
PCB design always has a few impedance discontinuities, how to do?
Similarly, there is also a parasitic inductance through the hole. In high-speed digital PCB, the harm caused by the parasitic inductance is often greater than the parasitic capacitance.
Some experience sharing about power PCB design, practical!
What is the core power supply, is some power supply current, the number of the kind. A plane, not more than 3 power supply division. It is important to consider that segmentation cannot present current-carrying bottlenecks.
High frequency PCB Design too Complex? You need to know these wiring tips
At the same time, it should be noted that the transmission line on the PCB should not have mutations or corners, and the impedance of each point of the transmission line should be kept continuous as far as possible, otherwise there will be reflections bet
Nowadays PCB design time is getting shorter
Therefore, the relationship between the hole and the pin inductive reactance must be considered and the priority of the pass hole specification must be set.
Interference analysis and countermeasure in high frequency PCB design
In PCB, there are only two kinds of transmission lines: strip line and microwave line. The biggest problem of transmission line is reflection, which will cause many problems.
How to solve EMI problem in multi-layer PCB design
Starting from the most basic PCB board, this paper discusses the function and design skills of PCB stacking in controlling EMI radiation.
Why PCB designs generally control 50 ohm impedance?
In terms of PCB design, 50 ohm is also selected after comprehensive consideration. In terms of PCB wiring performance, generally low impedance is better.
Rf circuit PCB design
According to experience, the effect of RF circuit not only depends on the performance of the RF circuit board itself, but also depends on the interaction with the CPU processing board.
PCB design of the core problem solution
these problems can be avoided. Because the design of the circuit board will vary according to different equipment, different use locations, different heat dissipation requirements, and different electromagnetic interference (EMI) situation, then the desig
