**Introduction** In many industrial and automotive applications, protecting interface transceivers from various electrical overstress events is a major concern. Transient Voltage Suppressor (TVS) diodes are commonly used for this purpose as they clamp voltage spikes by creating a low impedance current path. The electrical characteristics of TVS diodes are determined by several process factors. These … Read more

The RK3588 core board is a widely used 8K flagship SoC chip from Rockchip, and it is one of the domestic chips frequently used by many electronic engineers. When using the RK3588, EMC issues often arise. So, how can we reduce these EMC problems? 1. Mold Isolation Design Connectors should be recessed as much as … Read more
Gastric cancer can be classified based on anatomical locations into: cardia cancer (gastric cardiacancer, GCC), fundic cancer, body cancer, antral cancer, and mixed type (two or more sites) cancer. The composition ratio of gastric cancer at different sites is undergoing significant changes, with a trend towards proximal development. In recent decades, the incidence of cardia … Read more
We believe that everyone finds wiring to be an essential part of PCB design, and the rationality of the wiring determines the aesthetics and production costs of the PCB. It also reflects the performance of the circuit and heat dissipation, as well as whether the performance of the components can be optimized. This article will … Read more
