Their low surface energy significantly reduces signal loss, making them ideal for millimeter-wave radar and satellite communication equipment. These materials, represented by PTFE, are reinforced with composite glass fibers or ceramic powders to enhance mechanical properties while maintaining excellent thermal stability. In practical applications, although Teflon substrates are more difficult to process than ordinary FR4 materials, they perform exceptionally well in impedance control and temperature adaptability. This article combines engineering case studies to explore...
