RF PCB Material Types: The Complete Engineer’s Guide to High-Frequency Laminates RF PCB material types fall into four major families: hydrocarbon-ceramic (Rogers RO4000 series), ceramic-filled PTFE (Rogers RO3000 series, Taconic TLY), pure PTFE (RT/duroid), and thermoset high-speed laminates (Isola Astra MT77, Panasonic Megtron). The right choice depends on your operating…
High Tg FR4 PCB Material: Complete Technical Specifications and Selection Guide (2026) High Tg FR4 PCB material is an enhanced glass-reinforced epoxy laminate with a glass transition temperature of 170–180°C, specifically engineered to withstand lead-free assembly processes and high-temperature operating environments. Standard FR4 (Tg 130–140°C) softens during 260°C lead-free reflow,…
