Noise countermeasures in artwork design

In recent years, the adoption of DC/DC converters with excellent conversion efficiency has become common in electronic devices due to power-saving measures and the use of low-voltage ICs. However, on the other hand, issues such as noise generation and adverse effects on other circuits have become challenges, making noise countermeasures at the artwork design stage extremely important. Noise can vary significantly based on PCB patterns, including GND routing, minimizing current loops, and component placement. Our company conducts verification experiments using actual DC/DC circuits to visualize the differences in noise based on design quality with data. We propose optimal artwork designs from both theoretical and practical perspectives. We provide reliable technology to support the development of noise-resistant products.
