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.
