We are pleased to announce the arrival of our latest shipment of DiClad880 RF PCB.

Substrate Profile
Rogers DiClad 880 woven fiberglass reinforced, PTFE-based composites offer exceptional performance as PCB substrates. With a dielectric constant (DK) of 2.2 +/- 0.04 at 10 GHz/23°C and 1 MHz, these laminates ensure reliable signal transmission. They have a dissipation factor of 0.0009 at 10 GHz/23°C and 0.0008 at 1 MHz, indicating low signal loss. The TcDK of -160 ppm/°C (-10~140°C) ensures stable electrical properties over a wide temperature range. These substrates exhibit a moisture absorption rate of just 0.02% and feature a low coefficient of thermal expansion (CTE) of 25 ppm/°C in the X-axis, 34 ppm/°C in the Y-axis, and 252 ppm/°C in the Z-axis.

Substrates Features

1. Extremely Low Loss Tangent: Ensures minimal signal loss during transmission.

2. Excellent Dimensional Stability: Maintains the shape and size of the substrate under varying conditions.

3. Product Performance Uniformity: Consistent electrical and mechanical properties across the substrate.

4. Highly Uniform Electrical Properties: Ensures reliable performance across a wide frequency range.

5. Consistent Mechanical Performance: Provides stability and durability for the PCB.

6. Excellent Chemical Resistance: Withstands exposure to various chemicals.

7.Lowest Moisture Absorption among PTFE-based composites: Minimizes the impact of moisture on performance.

8. Stable DK over a wide frequency range: Ensures predictable signal behavior.

9. Low DK supports wider line widths for lower insertion loss: Allows for efficient signal transmission.
