Rogers RT/duroid 5870 High-Frequency Printed Circuit Board RT5870 PCB with Immersion Gold Coating
(Note: PCBs are custom-made products; the images and specifications provided are for reference only.)
Introduction
Today, we are excited to introduce the high-frequency PCB constructed from RT/duroid 5870 laminates.
RT/duroid 5870 is a glass microfiber reinforced PTFE composite developed by Rogers Corporation, specifically designed for demanding stripline and microstrip circuit applications.
Why Choose RT/duroid 5870 Material?
1.Exceptional Dielectric Constant Uniformity: The randomly oriented microfibers ensure outstanding dielectric constant consistency.
2.Uniform Dielectric Constant: The dielectric constant of RT/duroid 5870 laminates remains consistent across different panels and maintains stability over a broad frequency range.
3.Low Dissipation Factor: This characteristic extends the applicability of RT/duroid 5870 laminates into the Ku-band and beyond.
4.Ideal for Microstrip and Stripline Applications: Specifically engineered for these types of circuits.
