RO4830 Plus laminates are woven-glass-free thermoset dielectric materials with a stable dielectric constant and low insertion loss, as required by RF designers for millimeter wave automotive radar sensors. The design dielectric constant of RO4830 Plus laminates is approximately 3.03 at 77GHz (microstrip differential phase length method). The combination of Rogers’ low loss thermoset resin system and very low profile electrodeposited copper foil translates to a very low insertion loss of 1.5 dB/inch for 5mil laminates, as measured by the microstrip differential phase length method.
RO4830 Plus laminates are engineered for the cap layer on FR-4 multi-layer board designs, which are commonly used for 76- 81 GHz automotive radar sensor PCB applications. These thermoset laminates are free of woven glass, contributing to good laser drilling performance, and CAF resistance. RO4830 Plus laminates can be fabricated using standard epoxy/glass (FR-4) processes and are compatible with RO4400™ bondply. These PFAS-free laminates have the UL-V0 flame retardant rating and are lead free solder process compatible.
