Considerations for PCB Design Goals Functionality (power management, signal processing) Hardware Compatibility (whether interfaces are widely used and easily accessible, whether they are compatible with existing circuit boards, considering the official electrical component interfaces of Robomaster) Mechanical Structure Compatibility (considering mechanical mounting positions, standardizing screw sizes and hole positions, considering large interfaces that require screw … Read more

Experience Sharing on Electromagnetic Compatibility (EMC) Design in Product PCBs

by

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

EMC Considerations in PCB Design

As the saying goes, to shoot a person, first shoot the horse; to capture a thief, first capture the king. The best way to solve EMC issues is to establish EMC rules for the PCBA. The following are my personal insights for reference! 1. Layer Configuration 1.1 Is the number of layers set reasonably? 1.1.1 … Read more

Implementing a General Layout Scheme of Top/Left/Main in QT C++

I came across an article discussing this layout implementation, but the code was missing many components and could not run. It seems to be an AI-generated article, primarily emphasizing hands-on skills. Therefore, I borrowed the coding ideas and some code from that article to create a small demo that is functional and has all the … Read more

PCB Design Guide: Safety Regulations, Layout and Routing, EMC, Thermal Design, and Process

Safety Distance Requirements This includes electrical clearance (air gap), creepage distance (surface distance), and insulation penetration distance. 1. Electrical clearance: The shortest distance measured along the air between two adjacent conductors or between a conductor and the surface of an adjacent motor casing. 2. Creepage distance: The shortest distance measured along the insulating surface between … Read more

Key Elements for Post-Design PCB Inspection!

When a PCB board has completed its layout and routing, and there are no errors reported in connectivity and spacing, does that mean the PCB is finished? The answer is certainly no. Many beginners, as well as some experienced engineers, often rush through the process due to time constraints, impatience, or overconfidence, neglecting the post-design … Read more

How to Design Circuit Boards for Electromagnetic Interference Immunity?

by
How to Design Circuit Boards for Electromagnetic Interference Immunity?

The basic task of interference immunity design is to ensure that the system or device does not malfunction or lose functionality due to external electromagnetic interference, and does not emit excessive noise interference to avoid affecting the normal operation of other systems or devices. Therefore, improving the system’s interference immunity is also an important aspect … Read more
