What is RO4835™ Laminate?

Thermoset laminate materials, including FR-4, are affected by oxidation over
time and temperature. This can slightly increase the dielectric constant and
dissipation factor of the circuit substrate. The change rate and impact on
circuit performance vary based on design and operating temperature. Rogers’
RO4835™ laminate, part of the RO4000® series, offers enhanced stability at
high temperatures and is more resistant to oxidation than other hydrocarbon
materials. RO4835 laminates share similar electrical and mechanical properties
with RO4350B™ laminates and are designed for high frequency performance
and cost-effective circuit fabrication. It uses standard epoxy/glass (FR-4)
processes and is competitively priced.

For frequencies above 500 MHz, RO4000 materials are ideal due to their low
dielectric loss, making them suitable for RF microwave circuits and controlled
impedance transmission lines. The material’s thermal coefficient of expansion
(CTE) matches copper, ensuring excellent dimensional stability and reliable
plated through-hole quality in mixed dielectric multi-layer boards, even under
thermal shock. RO4000 laminates have a Tg of >280°C (536°F), ensuring stable
expansion characteristics throughout circuit processing temperatures.

RO4000 series laminates can be processed using standard FR-4 techniques
without specialized via preparation. They are rigid, thermoset laminates,
compatible with automated systems and scrubbing equipment for copper
surface preparation. RO4835 laminates are RoHS compliant and suitable for UL
94V-0 certified applications.
