What is RO4835IND™ LoPro® Laminate ?

RO4835INDTM LoPro® thermoset laminates are specially designed for 60-81 GHz short range (<30m)
industrial radar applications, where excellent electrical performance and cost-efficiency are equally
important. RO4835IND LoPro laminates also provide environmental reliability and interconnection
stability which are critical criteria for PCB material selection.

RO4835IND LoPro laminates have a low insertion loss at 60 GHz of 2.13dB/inch to meet customers critical
radar coverage requirement. Meanwhile, expanded weave fiber provides excellent Dk uniformity and
Rogers’ tight quality control provides low Dk variation from lot to lot. RO4835IND LoPro laminates are
compatible with standard epoxy/glass (FR-4) processes and have a higher fabrication yield rate compared
to conventional PTFE-based laminates. Both low material and fabrication cost make RO4835IND LoPro
laminates a cost-effective solution for industrial radar.

RO4835IND LoPro laminate’s low water absorption results in little change in RF performance through
environmental exposure. Its robust peel strength after thermal processes and superior dimensional
stability brings excellent interconnection stability.

This product is offered in dielectric thickness of 0.004” and panel size of 24×18”, 24×21” and 48×36” for
customers’ best utility rates. RO4835IND LoPro laminates are suitable for both cap layer on multilayer
FR-4 board design or inner layers for multi-layer design. RO4835IND LoPro laminates are compatible with
SpeedWaveTM 300P Prepreg, 2929 Bondply, RO4450TTM prepreg, RO4450FTM prepreg and FR-4 prepreg.
These laminates have the UL-V0 flame retardant rating and are lead free solder process compatible.
