In the rapid development of 5G communication, millimeter-wave radar, and IoT devices, the design quality of RF PCBs, which are the core of signal transmission and processing, directly determines the performance boundaries of the entire system. Once regarded as a ‘black art’ reliant on experience, RF design often required engineers to go through repeated trial … Read more
Electromagnetic compatibility (EMC) is a key indicator for measuring electronic products. The layout of the PCB, the arrangement of components, etc., can act as both sources of interference and targets of interference. Reducing and mitigating these electromagnetic interferences is crucial for enhancing the electromagnetic compatibility of products. This article discusses the design aspects of PCB … Read more
Power Integrity (PI) Power Integrity (Power Integrality), abbreviated as PI, is the process of verifying whether the voltage and current at the power source and destination meet the requirements. Currently, power integrity remains one of the biggest challenges in high-speed PCB design. Power integrity involves multiple levels, including chip level, chip packaging level, circuit board … Read more
With the development of microcontrollers, their applications in household appliances, industrial automation, production process control, and smart instruments are becoming increasingly widespread. However, various electrical devices within the same power system are closely interconnected through electrical or magnetic links, influencing each other. Electromagnetic oscillations caused by changes in operating modes, faults, or switching operations can … Read more
