Engineered for demanding RF and microwave applications, the RO4835T 0.6mm 1oz ENIG 2-Layer Thin High-Frequency PCB from PCBSync delivers exceptional electrical performance, dimensional stability, and long-term reliability. Built on Rogers Corporation’s industry-leading RO4835T laminate, this thin, low-loss circuit board is purpose-built for engineers designing 5G infrastructure, automotive radar, satellite communications, and high-speed wireless systems where signal integrity is non-negotiable.
Why Choose RO4835T Laminate?
RO4835T is a hydrocarbon ceramic-filled laminate offering a stable dielectric constant (Dk) of 3.33 and an exceptionally low dissipation factor (Df) of 0.0037 at 10 GHz. Compared to standard FR-4, RO4835T dramatically reduces signal loss at GHz frequencies, ensuring cleaner transmission, tighter impedance control, and consistent phase performance across wide temperature ranges. Its enhanced oxidation resistance significantly extends service life in high-temperature environments — a critical advantage for outdoor antennas and aerospace assemblies. Lead-free process compatible and UL 94 V-0 rated, RO4835T meets the stringent demands of modern RF design while remaining compatible with standard FR-4 PCB fabrication processes for cost-effective production.

ENIG Surface Finish for Superior RF Performance
The Electroless Nickel Immersion Gold (ENIG) finish provides a perfectly flat, highly solderable surface ideal for fine-pitch components, BGA packages, and wire bonding. ENIG offers outstanding corrosion resistance, a 12-month shelf life, and consistent electrical performance — making it the preferred choice for high-frequency and high-reliability applications where surface flatness directly impacts insertion loss and impedance accuracy.
