RO3203 High Frequency PCB
Introduction
RO3203 high frequency circuit materials are ceramic-filled
laminates reinforced with woven fiberglass. These materials have
been specifically engineered to provide exceptional electrical
performance and mechanical stability while remaining
cost-effective. As an extension of the RO3000 series, RO3203
materials stand out with their enhanced mechanical stability.
With a dielectric constant of 3.02 and a dissipation factor of
0.0016, RO3203 materials enable an extended useful frequency range
beyond 40 GHz.
Features
RO3203 has a thermal conductivity of 0.48 W/mK, indicating its
ability to conduct heat.
The volume resistivity is 107 MΩ.cm and surface resistivity of the material is also 107 MΩ.
RO3203 exhibits a dimensional stability of 0.8 mm/m in the X and Y
directions and it has a moisture absorption rate of less than 0.1%,
indicating its ability to resist absorbing moisture when exposed to
specific conditions.
The material has different coefficients of thermal expansion in
three directions. The Z-direction coefficient is 58 ppm/℃, while
the X and Y-direction coefficients are both 13 ppm/℃.
RO3203 has a Thermal Decomposition Temperature (Td) of 500℃ and a
density of 2.1 gm/cm3 at 23℃.
After soldering, the material exhibits a copper peel strength of
10.2 lbs/in and a flammability rating of V-0 according to the UL 94
standard, while also being compatible with lead-free processes.
