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.

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

PCB Inspection Checklist after PCB wiring layout
Some designs have many different requirements, and a PCB inspection checklist can help you keep track of everything that needs to be checked.
PCB Testing Methods Guide sharing
Before explaining the inspection work after the PCB wiring is completed, I will introduce three special wiring techniques for PCB. The routing of PCB LAYOUT will be explained from three aspects: right-angle routing, differential routing, and serpentine routing.Today author from QiHe smt pick and place machine discussing about it with you . Right-angle routing (three […]
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.
What are the functions of a resistor?
Resistance (resistance), we often call it R in daily life, the unit is ohm, if you want to define the resistance, it is the size of the resistance of the conductor to the current,
Parallel or series connection, LED drive circuit selection
After the advent of the LED era, we can see its presence in various aspects of life, whether in the automotive, intelligent, or industrial fields. Due to its high efficiency, energy conservation, long lifespan, environmental protection and other characteristics, it has become an optional solution for today’s lighting technology and is gradually being applied to lighting.
