The features of the high frequency VT-6710 laminate
Key Material Characteristics
Ceramic-Filled PTFE Composites
VT-6710 is a ceramic-filled PTFE composite laminate that combines the dielectric properties of PTFE with the thermal and mechanical benefits of ceramic fillers. This unique composition provides an excellent balance between electrical performance, thermal stability, and structural integrity, making it highly suitable for high frequency applications where both precision and durability are essential.
Higher Dielectric Constant (Dk) with Low Dissipation Factor (Df)
One of the standout features of VT-6710 is its higher dielectric constant (Dk) of 10.7. This provides a significant benefit for applications that require higher permittivity for miniaturization or performance optimization, such as military radar and satellite communications. Despite the high Dk, VT-6710 maintains an exceptionally low dissipation factor (Df) of 0.0022, ensuring ultra-low signal loss and high efficiency in signal transmission. This combination of high Dk and low Df is crucial for high frequency circuits, where maintaining signal integrity is of utmost importance.
Low Coefficient of Thermal Expansion (CTE)
VT-6710 exhibits a low CTE across the x, y, and z axes. This means the material is resistant to dimensional changes during thermal cycling, ensuring dimensional stability in environments that experience temperature fluctuations. Low CTE is a critical factor for ensuring reliable performance, particularly in high frequency circuits where precise alignment and consistent electrical characteristics are vital.
Low Moisture Absorption
VT-6710’s low moisture absorption makes it an ideal choice for applications in environments where exposure to humidity or moisture may be a concern. Moisture can affect the electrical properties of laminates, leading to signal degradation or performance inconsistencies. With minimal moisture absorption, VT-6710 maintains its electrical properties and performance over time, making it suitable for rugged, demanding environments.
Tight Dk and Thickness Tolerance Control
VT-6710 is designed with tight Dk and thickness tolerance control, ensuring consistency in material performance across different production batches.
