New Battlefield! The Global Competition Over "Circuit Boards" Heats Up 21st Century Business Herald As Tesla’s Robotaxi prepares to hit the roads and smartphone AI assistants grow increasingly "smarter," the circuit boards behind them are undergoing a technological revolution. Since 2025, the PCB (Printed Circuit Board) industry has seen multiple growth drivers—from AI data centers to new energy vehicles, foldable phones to robotics—the upgrade of electronic devices is fueling a surge in PCB demand. Domestic manufacturers are rapidly expanding high-end production capacity, and a "circuit board revolution" is underway. Below is a summary of the industry’s key growth drivers. 1. AI Servers "Devour" Circuit Boards: Costs Triple per Board Inside Nvidia’s AI server factory, the circuit boards are nothing like those in traditional computers—20+-layer "super PCBs" are densely packed with chips, with each board costing three times more than those in conventional servers. This is because AI training requires massive data transfers, pushing PCB layer counts from the traditional 8 layers to 20-30, with materials upgraded to high-speed, low-loss specialty substrates. Broadcom’s latest Tomahawk 6 chip boasts 102.4Tbps bandwidth, requiring even more precise PCB trace designs. Domestic supplier Shengyi Tech’s high-speed copper-clad laminates (CCL) have entered the supply chain, with prices five times higher than standard materials. Our new 6-layer hybrid PCB, built with M6 High Speed PCB material and High Tg FR-4, perfectly fits into this high-speed data transfer trend. It features 4/4 mils minimum trace/space, 0.2mm minimum hole size, and a copper coin embedded in the center for enhanced performance. The Megtron 6 material offers exceptional dielectric properties (DK 3.4 at 1GHz, 0.002 dissipation factor) and supports 4-30 layer designs, while Isola 370HR provides high thermal performance and reliability, making it ideal for complex circuit requirements in AI servers. Leading manufacturers like Shenghong Tech and Wus Printed Circuit already have AI server PCB orders backlogged until Q1 2026, with some running at full 24/7 capacity. Nvidia’s GB200 servers use 6-step 24-layer HDI PCBs, with each unit requiring five times the volume of traditional servers. Ping An Securities Research estimates that global high-layer (18+ layers) PCB output value will grow 41.7% in 2025. 2. Vehicle Electrification Doubles Automotive PCB Value In BYD’s Blade Battery management system,12-layer flexible PCBs and 3OZ heavy copper boards form the core of its electric control system. Engineers at Jingwang Electronics note that the PCB value per new energy vehicle now reaches ¥1,500-2,000—double that of traditional ICE vehicles—while L2+ autonomous driving domain controllers require 16-layer HDI boards, pushing prices above ¥5,000. Tesla’s self-driving control boards use Any-Layer HDI technology with laser-drilled holes as small as 0.1mm. Domestic suppliers’market share has risen from 30...

What Are the Future Development Trends of Low-loss Materials? Introduction As the demand for high-frequency, high-speed electronics continues to surge, the role of advanced PCB materials like Megtron 6 (M6) and FR408HR has become increasingly critical. These low-loss laminates are essential for applications in 5G communications, automotive radar, data centers, and aerospace systems, where signal integrity and thermal reliability are paramount. This article explores the future trends of low-loss materials, the technological advancements driving their adoption, and how leading PCB manufacturers are leveraging these materials to push the boundaries of performance. Additionally, we highlight our latest 6-layer Megtron 6 PCB, engineered for high-frequency and high-speed applications, as a prime example of next-generation PCB solutions. The Growing Importance of Low-Loss Materials Why Megtron 6 and FR408HR? Traditional FR-4 materials, while cost-effective, struggle with dielectric losses (Df) and signal degradation at high frequencies. In contrast, Panasonic Megtron 6 and Isola FR408HR offer superior electrical properties: Ultra-low dissipation factor (Df): Megtron 6: 0.002 @ 1GHz (vs. ~0.020 for standard FR-4) FR408HR: 0.010 @ 1GHz (optimized for high-speed digital) Stable dielectric constant (Dk): Megtron 6: 3.34 @ 13GHz (minimal variation with frequency) FR408HR: 3.70 @ 10GHz (balanced for digital & RF) Exceptional thermal performance: High Tg (>185°C) and Td (410°C) for reliability in harsh environments These properties make them ideal for 5G mmWave, automotive radar (77GHz), and 400G/800G optical modules, where signal loss and heat dissipation are critical challenges. Market Trends Driving Adoption 1) 5G & mmWave Expansion The rollout of 5G-Advanced and 6G will require even lower-loss materials to support higher frequencies (up to 300GHz). Megtron 6’s low Df (0.0037 @ 13GHz) makes it a top choice for mmWave antennas and RF front-ends. 2) AI & Data Center Boom AI servers demand ultra-high-speed interconnects (112Gbps+ SerDes). Megtron 6’s low insertion loss is crucial for PCIe 6.0 and 800G optical modules. 3) Automotive Radar & ADAS 77/79GHz radar PCBs require materials with minimal signal distortion. FR408HR offers a cost-effective alternative for mid-range ADAS applications. 4) Aerospace & Defense Satellite communications and phased-array radars need materials with stable Dk/Df across extreme temperatures. Introducing Our Latest Megtron 6 PCB: A Benchmark in High-Speed Design To meet these evolving demands, we have developed a 6-layer Megtron 6 PCB material R-5775G (HVLP) PCB, optimized for high-frequency and high-speed digital applications.
