RT/duroid 5870 PCB 2-layer 5mil

Shipped: 24th-May-2024

1. Introduction of RT/duroid 5870
Rogers RT/duroid 5870 high frequency laminates are PTFE composites reinforced with glass microfibers. They offer high frequency with low dielectric constant (Dk). The randomly oriented microfibers in the PTFE composites result in exceptional Dk uniformity. With its low Dk loss, RT/duroid 5870 laminates are well suited for high frequency/broadband applications where dispersion and losses need to be minimized.

2. Features
- Dielectric constant of 2.33 with tight tolerance 0.02 at 10 GHz/23°C
- Dissipation factor of 0.0012 at 10GHz, 0.0005 at 1MHz
- Strong copper peel strength of 27.2 pli
- Low Moisture Absorption 0.02%
- Td greater than 500 °C TGA
- CTE in X-axis of 22 ppm/°C, Y-axis of 28 ppm/°C and Z-axix of 173 ppm/°C
- UL 94-V0 flammability
- Isotropic

3. Benifits
- Lowest electrical loss for reinforced PTFE material
- Easily cut, shared and machined to shape
- Resistant to solvents and reagents used in etching or plating edges and holes
- Ideal for high moisture environments
- Well-established material
- Uniform electrical properties over wide frequency range
