What is DiClad laminates?

DiClad laminates represent a class of composite materials woven from fiberglass and PTFE, designed specifically for application as substrates in printed circuit boards. These laminates afford meticulous control over the ratio of fiberglass to PTFE, offering a spectrum of options ranging from the lowest dielectric constant and dissipation factor to a robust laminate with enhanced dimensional stability.

The woven fiberglass reinforcement found in DiClad products contributes to superior dimensional stability when compared to nonwoven fiberglass-reinforced PTFE-based laminates of similar dielectric constants. Rogers achieves this by ensuring consistency and control in the PTFE-coated fiberglass cloth, allowing for a diverse range of dielectric constants. Consequently, DiClad laminates exhibit improved dielectric constant uniformity in contrast to comparable nonwoven fiberglass-reinforced laminates.

The coated fiberglass plies in DiClad materials are meticulously aligned in a consistent direction, with crossplied versions available, such as the CuClad materials. DiClad laminates find frequent application in filter, coupler, and low noise amplifier scenarios, particularly where dielectric constant uniformity is paramount. Additionally, they are employed in power dividers and combiners, where minimizing loss is crucial.

What are DiClad 527 laminates?

DiClad 527 laminates, characterized by a dielectric constant (Er) ranging from 2.40 to 2.65, utilize a higher fiberglass-to-PTFE ratio. This design choice imparts mechanical properties approaching those of conventional substrates, along with notable advantages such as enhanced dimensional stability and reduced thermal expansion in all directions. The electrical properties of DiClad 527 laminates undergo rigorous testing at both 1 MHz and 10 GHz to ensure their performance across a broad frequency spectrum.
