Rogers Corporations (Chandler, AZ) [NYSE:ROG] next generation RO4000 materials, RO4835 high-frequency laminates, specially formulated with improved oxidation resistance were developed for applications needing a special level of electrical stability over time and temperature, while maintaining the cost advantages of a thermoset, FR-4 processable material.
Just as with RO4350B material, RO4835 laminates offer:
- A dielectric constant of 3.48 @ 10 GHz.
- A low loss tangent of 0.0037 @ 10 GHz.
- A low z-axis coefficient of thermal expansion.
- x- and y-axis expansion coefficients similar to that of copper.
- RoHS compliance.
Rogers’ RT/duroid, RO3000 and RO4000 laminates feature:
- Availability in several thicknesses of 1.5, 2, and 3 mm.
- A low dielectric constant of 2.94.
- A low dissipation factor of less than 0.003 in the z axis @ 10 GHz.
- A proprietary cross-linking resin system that supports sequential bond processing.
- Controlled flow characteristics for excellent blind via fill results.
Rogers’ halogen-free MCL-HE-679G/THETA laminates and prepreg products feature:
- RoHS-compliant MCL-HE-679G/THETA circuit materials.
- A relative dielectric constant of 3.90 in the z-direction @ 1 GHz.
- A low dissipation factor of 0.009 @ 1 GHz.
- A coefficient of thermal expansion of only 50 ppm/°C in the z direction.
