It has become a basic requirement today for electronic products to be lightweight and compact in size. However, the result is that the size on a PCB that is available for use becomes smaller and the layout density becomes significantly larger. For high-speed transmission, the frequency has to be increased in order to boost the transmission speed and the period of signal increase becomes shorter with the evolution of transmission protocols. All of the above make the signal integrity issues trickier than before and reduce the flexibility design for hardware engineers. Among all signal integrity issues, crosstalk has to be one of the toughest. Crosstalk is the jumping of interference signals from a dynamic line to the neighboring static lines, and exists in every pair of signal line. Crosstalk has been found in physical layers such as chipsets, packages, PCBs, connectors and cables, and it may render electronic products inoperable when it exceeds a certain level through overlapping. For this, it is imperative for engineers to find out and understand how crosstalk comes to be and how to reduce its impacts.

In the modern era, mobile phones are the most frequently used electronics in the world. Quality and performance are especially important to the user experience for its large usage. Under the popularization of smart phones, frequent charging has become a habit of users. In addition, most mobile phones now have a fast charging function, which is easy to cause EOS damage during high-power charging process and results in internal damage for normal usage then seriously affecting user experience.

The most popular technical term in 2018, AIoT, represents that we have entered a new era with the combination of “Artificial Intelligence” and the “Internet of Things,” and now it will continue to blow up in 2019. In order to reduce the gap between AI assistant and product features in the past, the collaboration of AI assistant with manufacturers of other peripheral products makes it easier for consumers to control many household appliances remotely. For example, a smart speaker can be placed anywhere in your home to create the most direct human-machine communication: operate hands-free with your voice. And the display on the smart refrigerator enables you to search for recipes. By using your personal ID virtual dialogue, it can read the recipes or morning news, or directly connect to a grocery shopping app to check the missing ingredients for a recipe from your refrigerator for you to organize the shopping list. New Smart Home experience provides you a convenient living space.
