Rogers launches new thermoset laminates

Electrical performance optimised for 76-81 GHz automotive radar applications

RO4830 Plus woven glass free, thermoset laminates possess the stable dielectric constant and low insertion loss required by RF designers for millimetre wave automotive radar sensors. The design dielectric constant of RO4830Plus laminates is approximately 3.03 at 77GHz (microstrip differential phase length method). The combination of Rogers’ new low loss thermoset resin 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.

PCB fabrication characteristics reduce overall PCB manufacturing costs

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 bond ply. These PFAS-free laminates have the UL-V0 flame retardant rating and are lead free solder process compatible.

RO4830 Plus laminates provide:

• Stable dielectric constant and low insertion loss at 77GHz via Rogers’new thermoset resin system combined with a very low profile Electrodeposited copper (VLP ED).
• New woven-glass free thermoset material maximises fabrication yield and efficiency, further reducing the overall cost of PCBs.

Available in dielectric thicknesses of 0.005, Rogers RO4830 Plus laminates are available in standard panel sizes of 24×18 in. (610x457 mm) 和24×20in. (610×508mm), 24×21in. (610×533 mm) with 0.5 oz. (18 µm) VLP ED.
