Introduction to CuClad 233 Material

Rogers CuClad 233 laminates are constructed using cross-plied woven fiberglass and PTFE composites, providing balanced electrical and mechanical properties. With a low dielectric constant (Dk) of 2.33 and dissipation factor of 0.0013, these laminates ensure low insertion loss and excellent dielectric uniformity. The cross-plied construction enhances dimensional stability, while the high PTFE-to-glass ratio supports consistent performance over a broad frequency range.

Key Features of CuClad 233

• Dielectric Constant (Dk): 2.33 at 10GHz/1MHz.
• Dissipation Factor: 0.0013 at 10GHz for minimal signal loss.
• Moisture Resistance: Low absorption rate of 0.02%.
• Peel Strength: High peel strength of 14 lbs/in for reliable bonding.
• Low Outgassing: Total mass loss (TML) and collected volatile condensable material (CVCM) are just 0.01%, ensuring suitability for space and vacuum applications.
• Dimensional Stability: Cross-plied construction provides unmatched stability compared to non-woven fiberglass laminates.

Benefits of CuClad 233

• Stable Electrical Properties: Consistent Dk and low loss across a wide frequency range.
• Reduced Circuit Losses: Supports wider line widths for lower insertion loss.
• Large PCB Support: Ideal for large-format designs like antennas.
• CTE Match with Aluminum: In-plane CTE matches aluminum, making it suitable for aircraft skins and structures.

Applications

Radars: Advanced radar systems for aerospace and defense.

Electronic Countermeasures (ECM): Reliable for military-grade signal disruption systems.

Microwave Components: Low noise amplifiers (LNAs), filters, couplers, and more.
