Introduction to PCB Materials and Applications 1. What is PCB Material? PCB material, which refers to the substrate material of printed circuit boards, serves as the carrier and interconnection framework for electronic components. It mainly consists of the following two parts: Core Material: Typically a copper-clad laminate, made by impregnating a reinforcing material with resin, … Read more
In the laboratory, an engineer repeatedly adjusts the high-speed signal link, but the waveform on the oscilloscope screen remains jittery—this is a common dilemma faced by many Chinese electronic R&D teams. “Bandwidth breaks through 90GHz, ranking first in the country and second in the world.” On October 15, at the 2025 Bay Chip Expo, this … Read more
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
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
8-Layer PCB Prototyping | High-Density Interconnection for AI and Data Centers In the wave of AI computing power explosion and data center upgrades, traditional PCBs can no longer meet the demands for high-frequency and high-density signal transmission. Our team encountered an urgent requirement from an AI server manufacturer—signal delays frequently occurred during data processing on … Read more

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
Analysis of the Reasons for Curved High-Speed Signal Traces on PCBA Boards 1. The Special Nature of High-Speed Signals and Routing Requirements In PCBA (Printed Circuit Board Assembly) design, high-speed signals typically refer to signals with frequencies above 100MHz or transmission rates exceeding 1Gbps, such as PCIe, DDR, USB 3.0, etc. The transmission of these … Read more
Challenges and Future Evolution of Optical Module Technology on PCBs As the core interconnection unit of computing infrastructure such as data centers and 5G communications, optical modules have undergone a technological evolution from 100G to 400G, 800G, and even 1.6T, which has imposed comprehensive technical reconstruction requirements on the PCBs (Printed Circuit Boards) that carry … Read more
