DiClad® 870/880 Laminates

DiClad® 870 and DiClad 880 laminates were developed to offer lower dielectric constant than the original GT/GX laminates. This is achieved by using fewer plies of woven fiberglass reinforced than DiClad 522 and DiClad 527 for the same dielectric thickness laminate. This provides a composite which achieves dielectric constant and loss tangent values among the lowest available. Building blocks for DiClad are built in high volume to support a variety of applications in microwave printed circuit boards designed for broadband telecom and high frequency applications.

Features

• Primary Dielectric Constant Targets at 2.17, 2.20 (DiClad 880) and 2.33 (DiClad 870)
• Low Dissipation Factor (Loss Tangent from 0.0009 to 0.0012 at X-band)
• Lowest Moisture Absorption Among PTFE Based Composites
• Stable Dk Over a Wide Frequency Range
• Available up to 48” x 54” Panels

Benefits
