Product Description

High-Performance RO4835 PCB - 0.8mm Double-Sided RF Board with Immersion Gold Finish
(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)


1. Premium RF Circuit Board Overview
This advanced double-sided PCB utilizes Rogers RO4835 laminate, a high-frequency material specifically engineered to deliver exceptional performance in demanding RF applications. Designed for automotive radar systems, microwave communications, and phased-array radar, this 0.8mm thick circuit board combines superior electrical properties with enhanced oxidation resistance, making it ideal for both commercial and industrial applications where reliability is paramount.
The board features a robust construction with immersion gold surface finish and green solder mask on both sides, providing excellent corrosion resistance and solderability. With 4/5 mil trace/space capability and resin-filled vias (IPC-4761 Type VII), this PCB offers designers the perfect balance of high-frequency performance and manufacturing efficiency.

Key Advantages:
Exceptional Signal Integrity: 3.48±0.05 dielectric constant with 0.0037 low loss at 10GHz
Thermal Reliability: >280°C glass transition temperature withstands harsh environments
Manufacturing Efficiency: Compatible with standard FR-4 processing
Dimensional Stability: CTE matched to copper (10/12 ppm/°C X/Y)
Oxidation Resistance: Superior to conventional hydrocarbon materials
