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.
Switching Power Supply: Uses Advantages and Working
A power supply is an electrical device that converts the electric current that comes from a power source to the voltage value necessary for powering a load, like a motor or an electronic device.
How to Optimize Switching Power Supply Layout
In a successful power supply design, power supply layout is one of the most important links. However, everyone has their own opinions and reasons for how to do this. The truth is, many different
How do you measure input and output impedance?
Input resistance is a measure of the amplifier’s effect on the signal source. The larger the input resistance, the smaller the current taken by the amplifier from the signal source, and the larger the signal voltage obtained at the input terminal of the amplifier,
Tips and PCB Design Guidelines for EMI & EMC
The sensitivity of electronic equipment is getting higher and higher, which requires the anti-interference ability of the equipment to be stronger and stronger, so PCB design has become more difficult
