Talk about the basic principles of PCB layering design
The power circuit and control signal circuit components need to be connected to different ground layers, which are generally connected through a single point.

Software anti-jamming design
In the design of high-speed DSP application system, how to transform perfect design from theory to reality depends on high quality PCB board, DSP circuit working frequency is getting higher and higher, pin more and more dense, interference increase, how t
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
Anti-interference design in PCB wiring
In the design of PCB routing, the input and output wires should avoid crossing as far as possible, and the feedback coupling can be avoided by adding capacitance between the wires.
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
The effect of PCB layer-stack design on EMI suppression is analyzed
In the case of the IC on our circuit board, the power layer around the IC can be regarded as a good high-frequency capacitor, which can collect the energy leaked by discrete capacitors that provide high frequency energy for clean output.
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).
Design concept and principle of microwave high frequency circuit PCB
a simple and applicable method is to first lay the ground wire, then place key signals such as high speed clock signals or sensitive circuits near their ground loops, and finally route other circuits. The layout of the signal line is best arranged accordi
