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.
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,
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

Introduction to Microcontrollers
The selection of single-chip microcomputer is an important and troublesome thing. If the type is selected properly, the product will be cost-effective and work stably; otherwise, it may cause excessive product cost or affect the normal operation of the product, and may even fail to meet the pre-design requirements at all.
