What is a PCB Step Slot? First, let’s briefly understand what a step slot is. In multilayer PCBs, conventional slots penetrate the entire thickness of the board. In contrast, a step slot is a non-through, depth-controlled slot that extends only to specific layers within the board, resembling a “step” in its cross-section, hence the name. … Read more
Reflecting on a decade of change and envisioning a new future. From September 24 to 26, the China (Shanghai) International Sensor Technology and Application Exhibition (SENSOR CHINA 2025) was grandly held at the Shanghai International Procurement Exhibition Center, marking its milestone tenth anniversary.

Abstract The next generation of satellites will take on the important task of addressing future challenges in communication, navigation, and observation. To achieve this goal, the number of orbital satellites is expected to continue to grow, making space exploration more cost-effective by constructing intelligent constellation systems and miniaturizing individual satellites. Ensuring that satellites possess precise … Read more
TSMC has advanced its process to 2 nanometers, which is a significant challenge, but from an architectural mechanism perspective, it is still an engineering difficulty! However, if you do not keep up step by step, you will ultimately be unable to truly engage with it! Although it is not a difficulty of profound mechanisms, the … Read more
1. The Endless Demand for Chip Miniaturization 2. Standard Cell Layout The standard cell layout generation process consists of five core steps Logic Definition (e.g., NAND2_X1 functional symbol) Circuit Implementation (PMOS/NMOS transistor network) Architectural Parameters (device selection/number of tracks/metal spacing) Transistor Layout (gate alignment/diffusion sharing) Internal Wiring (meeting design rules and pin accessibility) 3. Three … Read more
