Effective decoupling radius of decoupling capacitor
The decoupling radius is a measure of the effectiveness of a decoupling capacitor. It is a function of many factors, including the plane geometry, the frequency as well as the capacitor parameters.

How clock signal is generated in microcontroller?
Whether it is a single-chip microcomputer or a microprocessor, their core is a large-scale sequential logic circuit, and the power driving the sequential logic circuit is an accurate and stable clock source-don’t underestimate the attributive “accurate and stable”,
How do you know if a capacitor is bad on a circuit board?
There are tens of thousands of small electronic components in the circuit. Therefore, when our circuit design is improper or the voltage is unstable, it is easy to cause circuit failure
What Is Controlled Impedance in PCB?
PCBs have the unique job of carrying electric signals between connecting parts. These electronic signals are necessary for a device to perform its function, and it won’t work without them. These signals travel through signal traces that run through the PCB.
Key Points of Common Interface Types in PCB Design
We know that there may be some problems in the data exchange between the various sub-modules of the circuit system that cause the signal to fail to “flow” normally and with high quality.

What is PCB Shield ? – PCB Manufacturing skills
While the transmission rate of high-speed PCB design and wiring system is steadily accelerating, it also brings some anti-interference vulnerability.
How to Deal with Electromagnetic Compatibility in the PCB Design process
For the design of electromagnetic interference, we mainly design and process it from the aspects of hardware and software. Today qihe smt pick and place machine showing an introduction to the processing of electromag
Signal Ground VS Chassis Ground
The power ground is mainly for the path of the power loop current. Generally speaking, the current flowing through the power ground is relatively large,
How to Design a PCB Layout: A Comprehensive Guide
For many years, people have always believed that the fewer board layers, the lower the cost, but there are many other factors that affect the manufacturing cost of the board. In recent years, the cost.
