Impedance matching in high speed PCB design
Characteristic impedance is related to PCB wire layer, PCB material (dielectric constant), wire width, distance between wire and plane and other factors, and has nothing to do with wire length.

Methods of PCB design for antistatic release (ESD)
Adjacent to these connection points, a pad or mounting hole for mounting is placed between the case ground and the circuit ground. These ground connections can be cut open with a blade to keep the circuit open, or a jump with a magnetic bead/high frequenc
PCB design is extremely important
The basic concept of microstrip theory and the concept of microwave RF circuit and PCB design is actually an application aspect of microwave double transmission line theory.
The basic principle of DC power supply design in high speed PCB design
Power part and control part separate layout, power circuit is generally large voltage, large current, high power circuit, relatively large interference. And the control circuit is low voltage, if the control part to the power part, the control part is ver
Discussion on the importance of PCB design of switching power supply
In addition, whether the need for special treatment, such as copper foil, shielding, etc., also need to be considered in the PCB design stage.
Reflection of PCB design line width change
When the PCB wiring width changes, it should be carefully analyzed according to the actual situation to determine whether it will cause any impact. There are three parameters to be concerned about: how much impedance change, how much signal rise time, and
PCB original | high-speed PCB design software cascade structure design proposal
Test purpose: As PCB may be used in sea or seaside areas with high salinity in the air, its function will be affected due to poor salinity resistance, and serious accidents will be caused.
What is the theory of PCB design microwave dual transmission line?
For RF-PCB wiring, each adjacent signal line (including adjacent planes) is formed to follow the basic principle of double line features (this will be explained later).
RF PCB Design Guide: RF and microwave PCB assembly
Antenna return signal loss is an important consideration in RF and microwave PCB design. The return loss of any RF and microwave PCB board is defined as the power ratio between the forward and reflected waves at a given frequency.
Rule five Routing direction rules for high speed PCB design
In high speed PCB design, the circuit board characteristic impedance control and multi-load topology design directly determine the success or failure of the product.
PCB design Layout Guide for engineers
Once the CAD library, circuit board outline, and other setup tasks are complete, the design can begin to lay out. The first step in this process is to place the PCB component package on the board. Placing components on the board must meet three main requi
PCB design for temperature and pressure monitoring
When the temperature or pressure of the target environment is higher than the warning value, it will notify the user through the cloud, so that the user can know the situation of the target environment in the first time.
