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
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 […]
How to reduce PCB Design errors and increase efficiency
PCB circuit board design is a critical and time-consuming task, and any problems require engineers to check the entire design network by network and component by component.
