Rogers DiClad 870 High-Frequency PCBs: The Perfect Solution for High-Performance Applications

DiClad 870 laminates from Rogers are top-of-the-line woven fiberglass reinforced, PTFE-based composites specifically designed for printed circuit board substrates. These laminates offer a lower dielectric constant (Dk) compared to other laminates in the DiClad series, ensuring excellent performance in high-frequency applications. With a unique composition of PTFE and woven fiberglass, DiClad 870 laminates deliver unmatched reliability and performance.

Key Features:
DiClad 870 laminates come with exceptional features that set them apart in the market:

1. Low Dielectric Constant: With a Dk of 2.33 at 10 GHz and 1 MHz, 50% RH, DiClad 870 laminates provide superior signal integrity and minimal insertion loss.
2. Low Dissipation Factor: These laminates exhibit a dissipation factor of 0.0013 at 10 GHz and 0.0009 at 1 MHz, 50% RH, ensuring efficient signal transmission and reduced energy loss.
3. Temperature Stability: DiClad 870 laminates offer a TcDK of -161 ppm/°C in the range of -10~140°C at 10 GHz, guaranteeing stable performance across varying temperatures.
4. Durability: With an arc resistance of over 180 seconds, DiClad 870 laminates offer exceptional durability and reliability.
5. Moisture Resistance: DiClad 870 laminates have minimal moisture absorption, with a rate of only 0.02%, ensuring long-term stability and reliable performance.
6. Thermal Expansion Control: The laminates exhibit low coefficients of thermal expansion (CTE) in the X-axis (17 ppm/°C), Y-axis (29 ppm/°C), and Z-axis (217 ppm/°C), minimizing the risk of delamination and ensuring dimensional stability.
7. Strong Adhesion: DiClad 870 laminates provide excellent copper peel strength of 14 lbs/in at 10s @288°C, ensuring reliable adhesion.
8. Safety Compliance: These laminates have a flammability rating of UL 94V0, ensuring safety and compliance with industry standards.
