Read about typical applications this material is used for and much more.
RO3000 series laminates are ceramic-fi lled PTFE based circuit materials with mechanical properties that are consistent regardless of the dielectric constant selected. This allows the designer to develop multi-layer board designs that use different dielectric constant materials for individual layers, without encountering warpage or reliability problems.
Manufactured at Neltec®, the N9000 PTFE laminate system is the next generation material system designed for critical microwave components, antennas, power amplifiers and subassemblies.
The Nelco® N9000-13 RF is a next generation PTFE Performance. Blended product which combines the RF electrical properties of PTFE with the competitive performance features of Nelco’s proprietary N4000-13 epoxy.
N4000-13 – Tg210
The Nelco® N4000-13 series is an enhanced epoxy resin system engineered to provide both outstanding thermal and high signal speed / low signal loss properties.
ARLON’s new halogen-free low-loss system represents the next generation low-loss thermoset and prepreg system for high-speed and high-frequency printed circuit boards.
