High Frequency DiClad 870 Copper Clad Laminate Sheet

DiClad 870 laminates are woven fiberglass-reinforced PTFE composite materials formulated specifically for deployment as printed circuit board (PCB) substrates. Through precise regulation of the fiberglass-to-PTFE ratio, DiClad 870 laminates deliver a diversified product portfolio—spanning variants with ultra-low dielectric constant (Dk) and dissipation factor (Df), to highly reinforced grades optimized for enhanced dimensional stability.

The woven fiberglass reinforcement inherent to DiClad series materials confers superior dimensional stability compared to nonwoven fiberglass-reinforced PTFE laminates of equivalent dielectric constant. Rogers’ stringent consistency and process control over PTFE-coated fiberglass cloth not only enables a broader spectrum of available Dk values, but also yields laminates with improved dielectric constant uniformity relative to comparable nonwoven fiberglass-reinforced alternatives. The coated fiberglass plies within DiClad 870 materials are unidirectionally aligned; cross-plied configurations of most grades are offered under the CuClad product line.

DiClad 870 laminates are ideally suited for applications where dielectric constant uniformity is a critical performance criterion, including RF filters, couplers, and low-noise amplifiers (LNAs). They are also well-positioned for power dividers and combiners, where minimal signal loss is paramount.
