Offered in various configurations, RO4003C laminates utilize both 1080 and 1674 glass fabric styles with all configurations meeting the same laminate electrical performance specification. RO4003C laminates provide tight control on dielectric constant (Dk) and low loss while utilizing the same processing method as standard epoxy/glass but at a fraction of the cost of conventional microwave laminates. Unlike PTFE based microwave materials, no special through-hole treatments or handling procedures are required.
RO4003C materials are non-brominated and are not UL 94 V-0 rated. For applications or designs requiring a UL 94 V-0 flame rating, RO4835™ and RO4350B™ laminates do meet this requirement.
