It can be processed using standard fabrication techniques, simplifying manufacturing and reducing complexity. This ease of manufacturing enables smooth integration into existing production processes.
2.3 Excellent Electrical Performance:
The RO4003C PCB offers exceptional electrical performance, making it suitable for high-frequency and microwave applications. It has a low dielectric constant (DK) of 3.38 +/- 0.05 at 10GHz, providing excellent signal integrity and precise impedance control. The low dissipation factor of 0.0027 at 10GHz minimizes energy losses, ensuring efficient signal transmission and reduced signal distortion.
2.4 Thermal Management:
The RO4003C PCB features a thermal conductivity of 0.71 W/m/°K, facilitating efficient heat dissipation. This property helps in maintaining optimal operating temperatures and prevents overheating in demanding applications. The PCB's high glass transition temperature (Tg) exceeding 280°C ensures exceptional thermal and mechanical stability, even in challenging operating conditions.
2.5 Dimensional Stability:
The RO4003C PCB exhibits a low Z-axis coefficient of thermal expansion (46 ppm/°C) and CTE (11 ppm/°C in the X-axis and 14 ppm/°C in the Y-axis) matched to copper. These characteristics ensure excellent dimensional stability, reducing the risk of failures caused by thermal stresses. The PCB's stability enhances the reliability of surface-mounted assemblies and hybrid designs.
2.6 Wide Temperature Range:
The RO4003C 20mil laminate PCB offers a thermal coefficient of dielectric constant (TCDK) of +40 ppm/°C, ranging from -50°C to 150°C. This wide temperature range ensures stable electrical performance across varying environmental conditions, making it suitable for applications that experience temperature fluctuations.
2.7 Low Moisture Absorption:
RO4003C materials exhibit low moisture absorption of 0.06%, maintaining consistent electrical and mechanical properties even in humid environments. This property is crucial for applications that require reliable performance in high-moisture conditions.
2.8 Availability and Global Support:
The RO4003C PCB is available worldwide, making it readily accessible to customers across different regions. It is backed by Rogers' global support network, ensuring technical assistance and customer service.
In summary, the key advantages of the RO4003C PCB over other microwave laminates include its cost-effectiveness, ease of manufacturing, excellent electrical performance, thermal management capabilities, dimensional stability, wide temperature range, low moisture absorption, and global availability.
