Hits : 15

A. RO4000® Series

RO4000 hydrocarbon ceramic laminates and semi-cured sheets have been leading the industry. Widely used in microwave and millimeter wave designs, this low loss material is easier to use for circuit fabrication and provides consistent performance than traditional PTFE materials.

RO4000 Advantage:

Compatible with FR-4 manufacturing process, stable dielectric constant (Dk), high thermal conductivity (.6-.8 W/m.K), compatible with lead-free soldering processes, low Z-axis CTE, ensures high reliability plated through holes, optimized price/performance ratio, Dk range (2.55-6.15), UL 94 V-0 flame retardant ratings.

B. RO4000®LoPro® Laminate

Utilizing Rogers' proprietary technology, it supports the pairing of inversion-treated copper foils to standard RO4000 series materials. The resulting laminate reduces conductor loss, improves insertion loss and signal integrity, while offering other desirable attributes of the standard RO4000 laminate system.RO4000 ceramic hydrocarbon laminates enable superior high frequency performance and low cost circuit fabrication. They can be processed using a standard epoxy/glass (FR-4) process, eliminating the need to go through a specialized preparation process, thereby reducing manufacturing costs.


Low insertion loss, RO4003C™, RO4350B™ and RO4835™ Lopro® laminates available, multilayer board (MLB) capability, CAF-resistant properties.


Reduced insertion loss, support for higher frequency designs (above 40 GHz), reduced passive intermodulation (PIM) of base station antennas, reduced conductor losses, improved thermal performance of circuits.

C. RO4003C™ Laminate

Rogers RO4003C material is a proprietary glass cloth-reinforced, ceramic-filled hydrocarbon composite material that combines the electrical properties of PTFE/glass cloth with the processability of epoxy/glass.

RO4003C laminates are available in two different configurations with 1080 and 1674 glass cloth. All configurations have the same electrical performance specifications. RO4003C laminates have been subjected to stringent process control, the material has a consistent dielectric constant (Dk) and low loss characteristics, and its unique mechanical properties allow it to be processed in the same way as standard epoxy/glass at a much lower cost than traditional microwave laminates. Unlike PTFE microwave materials, this material requires no special through-hole processing or handling procedures.

RO4003C material is not brominated and is not UL 94 V-0 compliant. For applications or designs that require a UL 94 V-0 flame retardant rating, RO4835™ and RO4350B™ laminates can fulfill this requirement.

RO4350B laminates offer tight tolerance control of dielectric constant (Dk), along with low loss characteristics, and are processed in the same manner as standard epoxy/glass. RO4350B laminates do not require special through-hole treatments or handling procedures like PTFE materials, and are far less expensive to process than traditional microwave laminates. The material achieves a UL 94 V-0 flame retardant rating and is suitable for active device and high power RF designs.
