Material Overview: Rogers RT/duroid 5880
Rogers RT/duroid 5880 is a premium high-frequency laminate designed for stripline and microstrip circuits. Its randomly oriented glass microfibers deliver exceptional dielectric constant uniformity, while its PTFE base ensures low electrical loss—making it ideal for applications requiring reliability across wide frequency ranges. The material is resistant to all solvents and reagents (hot or cold) used in PCB etching, plating, and processing, and it supports lead-free manufacturing processes.
