2L RO3006 RF PCB 1oz Copper White Silkscreen With ENIG

Introducing our newly shipped PCB made of RO306 substrates.

RO3006 Introduction:
Rogers RO3006 laminates are advanced circuit materials that utilize ceramic-filled PTFE composites. These materials are specifically designed to offer exceptional stability in both electrical and mechanical properties. One notable feature of RO3006 is its ability to maintain a stable dielectric constant (Dk) over a wide temperature range. This characteristic eliminates the step change in Dk that is commonly observed in PTFE glass materials near room temperature.

Features:
RO3006 laminates from Rogers consist of ceramic-filled PTFE composites. These materials exhibit a dielectric constant of 6.15 +/- 0.15 at 10 GHz and 23°C, along with a low dissipation factor of 0.002 at the same frequency and temperature. With a high thermal decomposition temperature exceeding 500°C, RO3006 demonstrates excellent thermal stability. It also offers a thermal conductivity of 0.79 W/mK, facilitating efficient heat transfer. In terms of moisture absorption, RO3006 boasts a low rate of 0.02%. Additionally, the material's coefficient of thermal expansion ranges from 17 ppm/°C to 24 ppm/°C (-55 to 288 °C) in the X, Y, and Z axes.

Benefits:
RO3006 laminates provide uniform mechanical properties across a range of dielectric constants, making them ideal for multi-layer board designs that require different dielectric constants. These laminates are also compatible with hybrid designs that involve epoxy glass multi-layer boards. Another advantage of RO3006 is its low in-plane expansion coefficient, which matches that of copper. This characteristic enhances the reliability of surface-mounted assemblies and makes it suitable for applications sensitive to temperature changes. Furthermore, RO3006 exhibits excellent dimensional stability. The volume manufacturing process used for these laminates ensures economical pricing, making them a cost-effective choice.
