Processing Series 5: Does a Larger Line Spacing Mean Less Insertion Loss? Decoding the Four Core Metrics of High-Speed PCBs: Dk, Df, Impedance, and Insertion Loss

Hello everyone! As PCBs enter the era of high-frequency and high-speed design, printed circuit boards are no longer merely a “base” for supporting electronic components. In addition to their basic conductive functions, they now shoulder the critical responsibility of transmitting high-frequency and high-speed signals.

2026 Memory Tsunami Through 2027: Samsung and SK Hynix Warn of "Inventory Wars"—What Does This Mean for the Taiwan PCB Supply Chain?

For Taiwan’s ODMs, OEMs, and system R&D centers, the air in May 2026 is thick with the scent of anxiety and burning cash. On April 30, memory giants Samsung and SK Hynix released their Q1 2026 earnings reports—and they weren't just showing off impressive numbers; they were issuing an ultimatum to the global hardware supply chain. As memory prices enter a "hourly dynamic pricing" era, the PCB is no longer just a carrier for circuits; it has become the "safety deposit box" protecting the world's most expensive chips.

DFM Practical Series 26: Unveiling the Mystery of the "Fake 8-Layer Board": Stackup Secrets Every RD and Layout Engineer Must Know

For RD and PCB Layout engineers fighting on the front lines, designing a stackup often involves a tug-of-war between "impedance control," "board thickness," and "manufacturing cost." When negotiating with PCB fabrication houses, you might have heard them suggest a special structure called a "fake 8-layer board" (or dummy 8-layer board). If the schematic only calls for a 6-layer routing plan, why upgrade to an 8-layer structure? Is this a waste of budget, or does it hide some manufacturing ingenuity? Today, we will thoroughly analyze this special multi-layer board design structure.

DFM in Practice: The Savior for Board Warpage – Copper Balance and Stress Relief Design

In today's era of lightweight, thin, short, and small electronics, combined with high-speed and high-frequency requirements, the physical stability of Printed Circuit Boards (PCBs) has become a severe challenge for R&D engineers and packaging process experts. With the increase in component packaging density—especially the widespread application of Ball Grid Array (BGA) and Chip Scale Packaging (CSP)—even microscopic deformations in a PCB can lead to catastrophic manufacturing yield losses.

Industry Insight: Upstream Materials Welcome a "Pricing Feast" as AI Computing Power Ignites a PCB Super Shortage Cycle

As AI computing power experiences explosive growth, chip areas continuously challenge physical limits, and AI Agents reconstruct the overall computing architecture, the resonance of these three mega-trends is pushing the PCB and IC substrate industry into an unprecedented "super shortage cycle." The entire supply chain is undergoing a comprehensive upgrade from traditional consumer electronics accessories to core components of AI computing infrastructure. Recent in-depth reports clearly indicate that from 2026 to 2028, the entire industry chain will face persistent capacity crowding and material shortage crises. Upstream high-frequency materials and ABF substrates will be the absolute core of this "volume and price surge" dividend.

eCloud Technology Tech Column: Engineering Practices and Design Trade-offs of High-End PCB Conductive Copper Paste Plugging

As the power density of servers, Electric Vehicles (EV), and high-frequency microwave communications (RF) continues to surge, the greatest challenge hardware engineers face during PCB layout is often not a lack of space, but rather "heat dissipation" and "current carrying limits."
