Rogers DiClad 870 High Frequency PCB Built on 5mil Substrate with Immersion Silver for Radar, Antenna and Microwave Applications
Printed Circuit Boards are custom-made products; the images and specifications provided are for reference only.
1. Introduction
Rogers DiClad 870 is a high-performance printed circuit board utilizing woven fiberglass reinforced PTFE-based composite laminate. It is designed for high-frequency and RF applications requiring stable electrical performance and low signal loss. Compared with other laminates in the DiClad series, DiClad 870 high-frequency laminate provides lower dielectric constant and dissipation factor at similar thickness by using fewer plies of woven fiberglass and a higher ratio of PTFE content, making it an ideal substrate for high-performance microwave and RF circuits.
2. Rogers DiClad 870 PCB Features
- DK of 2.33 at 10 GHz and 1 MHz, 50% RH
- Dissipation factor of 0.0013 at 10 GHz, 0.0009 at 1MHz, 50% RH
- TcDK of -161 ppm/°C ranging -10~140°C, 10 GHz
- Arc Resistance >180 seconds
- Moisture Absorption 0.02%
- CTE in X-axis of 17 ppm/°C, Y-axis of 29ppm/°C and Z-axis of 217ppm/°C
- Copper Peel Strength of 14 lbs/in, 10s @288°C
- Flammability of UL 94-V0 grade
3. Rogers DiClad 870 PCB Benefits
- Lowest moisture absorption among PTFE based composites
- Stable Dk over a wide frequency range
- Low Dk supports wider line widths for lower insertion loss
