Introduction of RO4003C
Rogers RO4003C materials are woven glass reinforced hydrocarbon/ceramics that provide the high-frequency performance of PTFE with the manufacturability of epoxy/glass. This low-loss material is suitable for RF microwave circuits and matching networks, allowing for competitive circuit fabrication.
RO4003C laminates are available in various configurations, using both 1080 and 1674 glass fabric styles, all meeting strict electrical performance specifications. The material is non-brominated and not UL 94 V-0 rated.
