Introducing RT/duroid 5880 and RO4003C: Unleashing High-Frequency PCB Performance

Introduction:
When it comes to high-frequency printed circuit boards (PCBs), the selection of materials can make all the difference in achieving optimal performance. Rogers Corporation offers two exceptional options that deserve recognition: RT/duroid 5880 and RO4003C. These materials possess unique characteristics and advantages that enhance the performance of high-frequency and broadband applications. Let's explore their distinctive features and discover how their hybrid combination can elevate your PCB designs.

RT/duroid 5880: Unleashing High-Frequency Potential
RT/duroid 5880 stands out as an outstanding high-frequency PCB material. It combines PTFE composites with glass microfiber reinforcement, resulting in a low dielectric constant (Dk) and minimal dielectric loss. This makes it an ideal choice for high-frequency and broadband applications. The random orientation of glass microfibers within the PTFE composites ensures uniform Dk and reliable signal performance. RT/duroid 5880 boasts a remarkable dissipation factor of only 0.0009 at 10GHz, thereby minimizing signal loss and distortion. Furthermore, its isotropic nature and low moisture absorption contribute to its overall reliability.

RO4003C: Achieving Performance and Cost Efficiency
RO4003C, another exceptional material from Rogers Corporation, harnesses a proprietary composition of woven glass reinforced hydrocarbon/ceramics. This unique blend combines the electrical performance of PTFE/woven glass with the cost-effective manufacturability of epoxy/glass, making it an excellent choice for high-frequency PCBs. With a precise Dk of 3.38 +/- 0.05 and a dissipation factor of 0.0027 at 10GHz, RO4003C provides meticulous control over electrical characteristics. Notably, it eliminates the need for special handling procedures and offers stability in varying temperatures with its low Z-axis coefficient of thermal expansion at 46 ppm/°C.
