Connecting a Resistor and Capacitor Between PCB GND and Chassis GND for Better Performance

The chassis is made of metal, and there is a screw hole in the middle, which connects to the ground. Here, a 1M ohm resistor is connected in parallel with a 0.1uF capacitor to the ground of the circuit board. What are the benefits of this setup? If the chassis ground is unstable or has … Read more

Electromagnetic Compatibility Design of Printed Circuit Boards

Electromagnetic compatibility refers to the ability of a device or system to function properly in its electromagnetic environment without causing unacceptable electromagnetic interference to anything in that environment. The purpose of electromagnetic compatibility design is to ensure that electronic devices can suppress various external interferences, allowing them to operate normally in specific electromagnetic environments, while … Read more
