General Description

Rogers DiClad 870 PCBs are woven fiberglass/PTFE composite materials specifically designed for use as printed circuit board (PCB) substrates, making them well-suited for applications requiring reliable RF and microwave performance. A key advantage of these laminates lies in their woven fiberglass reinforcement: when compared to nonwoven fiberglass-reinforced PTFE-based laminates with similar dielectric constants, DiClad 870 delivers significantly greater dimensional stability—an essential property for maintaining PCB structural integrity during manufacturing and long-term use.

What further distinguishes DiClad 870 from other laminates in the DiClad series is its optimized material composition. By utilizing fewer plies of woven fiberglass and a higher proportion of PTFE content, this laminate achieves lower dielectric constants (Dk) and dissipation factors (Df) while maintaining a thickness comparable to other DiClad products. These characteristics make it a preferred choice for PCB designs where signal loss minimization and high-frequency performance are critical.

Features & Benefits
