With the widespread adoption of 5G communication technology and the initiation of preliminary research on 6G, the electronic information industry has reached an unprecedented level of demand for signal transmission speed and quality. Against this backdrop, copper-clad laminates (CCL)—the core substrate material for printed circuit boards (PCBs)—are undergoing a revolutionary transformation in materials science. Among the many high-frequency, high-speed substrate solutions, High-frequency, high-speed hydrocarbon resin Thanks to its excellent dielectric properties, it is gradually replacing conventional materials and has become a key raw material in the high-end electronic circuitry sector.
Before delving into the materials, we must first understand the industry’s key pain points. In high‑frequency signal transmission—typically above 1 GHz—signal loss occurs as the signal propagates through the dielectric medium, and this loss is primarily governed by the substrate’s dielectric constant (Dk) and dissipation factor (Df). While conventional epoxy resins boast mature manufacturing processes, their relatively high Df in high‑frequency applications leads to significant signal attenuation and excessive heat generation, making them inadequate for meeting the demands of millimeter‑wave radar systems, AI servers, and 5G base stations.
At this point, hydrocarbon resins emerged. These resins are characterized by molecular structures dominated by carbon–hydrogen (C–H) bonds, resulting in very low polarity. According to physical principles, the lower a molecule’s polarity, the smaller its dielectric constant and dielectric loss. Consequently, after undergoing specialized modifications… High-frequency, high-speed hydrocarbon resin , capable of achieving extremely low Dk and Df values, it is an ideal substrate for lossless high-speed signal transmission.
Core Performance Analysis: Why Choose High-Performance Hydrocarbon Resin?
Compared with the costly PTFE (polytetrafluoroethylene) material, high-performance hydrocarbon resins offer superior processability and cost advantages while maintaining low dielectric properties. As a seasoned technology leader in the industry, Disai New Materials Significant efforts have been devoted to the research and development of modified hydrocarbon resins, with notable performance advances achieved across the following key dimensions:

1. Excellent low dielectric properties: High‑quality low‑dielectric hydrocarbon resins typically achieve a Df value of 0.002 or lower, and in some cases even lower. This translates to shorter signal delays and improved signal integrity during high‑speed data transmission.
2. Excellent heat resistance and dimensional stability: During the lamination of multilayer boards and the soldering of PCBs, materials are subjected to high-temperature conditions. High-performance hydrocarbon resins undergo crosslinking and curing, forming a dense three-dimensional network structure that imparts a high glass transition temperature (Tg) and a low coefficient of thermal expansion, thereby ensuring that the circuit board remains delamination‑free and maintains its dimensional stability under elevated temperatures.
3. Extremely low water absorption: Water molecules are polar, and water absorption can severely degrade a material’s dielectric properties. The inherently hydrophobic nature of hydrocarbon resins enables them to maintain stable electrical performance even in humid environments.
Empowering the Future: Disai New Materials’ Application Scenario Deployment
Based on the aforementioned characteristics, High-frequency, high-speed hydrocarbon resin It has been widely adopted across multiple high-end manufacturing sectors.
