Key Materials for the 5G Era: Why High-Frequency, High-Speed Hydrocarbon Resins Have Become the “New Favorite” in the CCL Industry?

With the widespread adoption of 5G communication technology and the initiation of preliminary research into 6G technology, the electronics information industry has reached an unprecedented level of demand for signal transmission rates and quality. Against this backdrop, clad copper laminates (CCL)—the core substrate material for printed circuit boards (PCBs)—are undergoing a revolution in materials science. Among the many high-frequency, high-speed substrate solutions available, High-frequency, high-speed hydrocarbon resin Thanks to its excellent dielectric properties, it is gradually replacing traditional materials and becoming a key raw material in the field of high-end electronic circuits.
Before delving into the materials, we first need to understand the industry’s pain points. In high-frequency signal transmission—typically above 1 GHz—signals experience losses as they propagate through a medium. These losses are primarily determined by the substrate’s dielectric constant (Dk) and dissipation factor (Df). Although traditional epoxy resins boast mature manufacturing processes, their relatively high Df values in high-frequency environments lead to significant signal attenuation and heat generation, making them unable to meet the demands of millimeter-wave radar, AI servers, and 5G base stations.
At this point, hydrocarbon resin emerged. The molecular structure of these resins is primarily composed of carbon-hydrogen bonds (C-H), which exhibit extremely low polarity. According to the principles of physics, the lower the polarity of a molecule, the smaller the material's dielectric constant and loss factor will be. Therefore, after undergoing special modifications, High-frequency, high-speed hydrocarbon resin It can achieve extremely low Dk and Df values, making it an ideal medium for realizing “lossless” transmission of high-speed signals.
Core Performance Analysis: Why Choose High-Performance Hydrocarbon Resin?
Compared to the expensive PTFE (polytetrafluoroethylene) material, high-performance hydrocarbon resins offer superior processing performance and cost advantages while maintaining low dielectric properties. As a technology pioneer in the industry, Disai New Materials Significant efforts have been devoted to the modification and R&D of hydrocarbon resins, with breakthroughs in performance primarily reflected in the following dimensions:

1. Excellent low dielectric properties: High-quality low-dielectric hydrocarbon resins typically have a Df value that can be controlled to within 0.002 or even lower. This means that during high-speed data transmission, signal delay is shorter and signal integrity is improved.
2. Excellent heat resistance and dimensional stability: During the lamination of multilayer boards and PCB soldering processes, materials must withstand high-temperature conditions. High-performance hydrocarbon resins undergo crosslinking and curing to form a dense three-dimensional network structure, giving them a high glass transition temperature (Tg) and a low coefficient of thermal expansion. This ensures that the circuit boards remain non-delaminated and do not deform under high temperatures.
3. Extremely low water absorption rate: Water molecules are polar, and their absorption can severely degrade the dielectric properties of a material. The naturally hydrophobic nature of hydrocarbon resins enables them to maintain stable electrical performance even in humid environments.
