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 24x18”, 24x21” and 48x36” 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.
