Eight Scarce PCB Segments Where Backplanes and Substrates Matter The AI computing power wave is reshaping the PCB industry pattern. Traditional ordinary PCB capacity is excessive, while supply and demand in high-end fields are seriously imbalanced. Combining the June 2026 Goldman Sachs research report and industry chain survey data, eight…

Decoupling Capacitor Placement and Routing Across the Frequency Range Decoupling capacitor layout and routing is not simply placing capacitors close to power pins. It is a systematic PCB design task that must strictly follow physical and electrical hierarchy relationships. Its core goal is to maintain the impedance at the IC…

Trace Spacing Rules for Reliable Circuit Boards In PCB design,PCB trace spacing (also called conductor spacing or trace clearance) is critical. It directly affects circuit reliability, signal integrity, manufacturing yield, and safety. Below are the key considerations and recommendations for setting trace spacing. Core Influencing Factors Electrical Safety (Insulation Requirements)…

Flexible PCB Core Logic: From Base Materials to Manufacturing In thin and light devices such as folding screen phones, smartwatches, and Bluetooth earphones, there is another kind of black technology hidden inside: FPC circuit boards, also known as flexible printed circuit boards. They can bend, fold, and twist, as soft…

Rigid, Flexible, and HDI: How PCB Manufacturing Processes Differ The manufacturing process of PCB directly determines its form, performance, and applicable scenarios. Rigid PCB meets fixed installation needs, flexible PCB adapts to bendable devices, and special process PCB such as high-frequency and HDI supports high-end functions. Classified by manufacturing process,…

PCB CAM Basics: The Software Behind PCB Manufacturing 1. The Concept of PCB CAM Everyone is familiar with the concept of CAD, but when using a photo plotter, the concept of CAM is essential. Because each factory has different process flows and technical levels, to achieve the user’s final requirements,…

Printed Circuit Board Basics: Structure, Materials, and Technology In the complex world of modern electronic devices, the printed circuit board, or PCB, is like an unsung hero. Although it is not eye-catching, it plays a vital foundational role. From tiny smartphones to massive supercomputers, from everyday home appliances to advanced…

From Basic Structure to HDI: The Evolution of Automotive PCB Technology 1. Basic Understanding of PCB: The Skeleton of the Electronic World When you first open a phone or computer, the green board covered with traces and small parts always makes people curious. This is the PCB, or printed circuit…
