Electrical performance optimized for 76-81 GHz automotive radar applications: RO4800™ 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. Rogers has two design dielectric options, 3.03 and 3.16 at 77GHz (measured using the 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.
PCB fabrication characteristics which reduce overall PCB manufacturing costs: RO4800™ 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. RO4800 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.
