What Is Impedance? Isn’t It The Same As Resistance? Regarding impedance (Impedance), I have found that many newcomers to this concept often confuse it with resistance (Resistance). This confusion may arise because both terms contain the character for “resistance” in Chinese, and both units are expressed in Ω. Additionally, impedance and resistance are related to … Read more
Introduction With the growing demand for networking, the issue of gigabit Ethernet speed has garnered significant attention. This article analyzes the low actual speed situation, detailing reasons such as poor wiring, and provides effective methods for improving speed and stability from both hardware aspects like equal-length wiring and impedance matching, as well as software debugging … Read more
As medical wearable devices and personal electronics continue to trend towards miniaturization, the requirements for the electronic components integrated within them are becoming increasingly stringent. In particular, medical-grade wearable devices must not only be smaller, lighter, and thinner in physical dimensions but also meet critical metrics essential for medical applications, including high precision, high reliability, … Read more
PCB Copper Pour refers to the area filled with copper in a PCB layer. This layer can be on the top, bottom, or any internal layer of the PCB, and PCB copper pour can be used for grounding, reference, or to isolate specific components or circuits from the rest of the elements on that layer. … Read more
