Grounding is crucial when designing printed circuit boards (PCBs). One common method is star grounding. But what exactly is star grounding? And why is it important for your PCB design? Let’s break it down. What is Star Grounding? Star grounding is a method of connecting different parts of a circuit to a single grounding point. … Read more
Load cells, as the core components for precise weight measurement, are widely used in various fields such as industrial production, logistics transportation, medical equipment, and food processing. Their performance and lifespan are highly dependent on the operating environment. When exposed to certain extreme or harsh conditions, not only can the accuracy of the sensors fail, … Read more
Electromagnetic compatibility (EMC) is a key indicator for measuring electronic products. The layout of the PCB and the arrangement of components within the product serve as both sources of interference and targets for interference. Reducing and mitigating these electromagnetic interferences is crucial for enhancing the EMC of products. This article discusses the design aspects of … Read more
In the rail transit scenario,LCD rail transit display screens are widely used in information display systems due to their advantages of high brightness, low power consumption, and long lifespan. However, some users have reported a phenomenon known as “screen flicker,” where the image exhibits periodic brightness changes or shaking. Is this issue solely caused by … Read more
Identifying the Cause of Interference When there is interference on the bus, experienced engineers can quickly locate the issue, but it can be troublesome for beginners. There are many causes of bus interference, such as electromagnetic radiation coupling into communication cables, improper grounding of shielded wires, and isolation of communication without isolating the power supply. … Read more
The application of magnetic modulation current sensors in industrial automation brings significant benefits in various aspects, mainly including: 1. Safe and Reliable Non-Contact Measurement Magnetic modulation current sensors measure current in a non-contact manner, which means that measurements can be completed without physical contact with live conductors, greatly enhancing operational safety and reducing the risk … Read more

Power Integrity (PI) Power Integrity (PI) refers to the verification of 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 aspects at the chip level, chip package level, circuit board level, and system level. … Read more
Recently, we have been testing a project, which included a special requirement: to detect whether materials on the PCB are missing.. Due to budget constraints, we initially opted for a 2D camera solution. By capturing images of the PCB surface, analyzing the imaging changes, and using specific algorithms to complete the detection. However, during batch … Read more
