Elevate your industrial RF applications with the RO4835IND LoPro 2.0mm 2-Layer Heavy Industrial RF Control Board. Specifically engineered for high-performance millimeter-wave (mmWave) systems, this board utilizes the industry-leading Rogers RO4835IND™ LoPro® laminate. This material is the gold standard for 60 GHz to 81 GHz industrial radar, providing a level of electrical stability and oxidation resistance that standard FR-4 or even traditional thermoset laminates simply cannot match.
Designed for PCBSync, this 2-layer control board combines the precision of high-frequency engineering with the “Heavy Industrial” durability of a 2oz copper weight and ENIG surface finish.

Why Choose RO4835IND for Heavy Industrial RF?
1. Superior Oxidation Resistance
The RO4835IND series is formulated with specialized antioxidant fillers. In industrial environments where boards are subjected to elevated temperatures and humidity, traditional laminates often suffer from “aging” that shifts the dielectric constant. The RO4835IND provides 10x better oxidation resistance, ensuring your RF performance remains consistent over a 10+ year service life.
2. LoPro® Technology for Low Insertion Loss
Signal integrity is paramount at mmWave frequencies. This board features Rogers’ proprietary LoPro® reverse-treated ED copper foil. By minimizing the surface roughness of the copper at the dielectric interface, the LoPro technology significantly reduces conductor loss, enabling higher efficiency in power amplifiers and radar sensors.
3. Heavy 2oz Copper for Thermal Management
While many RF boards use 0.5oz or 1oz copper, our “Heavy Industrial” variant utilizes 2oz copper. This extra mass allows for:
-
High Current Handling: Safely powers control circuitry and RF components on the same board.
-
Superior Heat Dissipation: Rapidly wicks heat away from active RF components, maintaining signal stability and preventing thermal throttling.
4. Precision ENIG Finish
The Electroless Nickel Immersion Gold (ENIG) finish provides a perfectly flat surface for fine-pitch SMT components. Beyond its excellent solderability, the gold layer protects the underlying nickel from corrosion—a critical feature for sensors deployed in harsh industrial settings.
Core Applications
-
Industrial Radar: Ideal for 60-81 GHz short-range radar (<30m) in tank level sensing and industrial automation.
-
Automotive Active Safety: Collision avoidance and blind-spot detection.
-
5G Infrastructure: High-frequency point-to-point backhaul and small cell systems.
-
Power Amplifiers: High-power RF stages requiring robust thermal paths.
