Adhesive Film FALDA™Polyimide Low Dielectric/Low Dielectric Loss Tangent Adhesive Film (Development Product)
FALDA™ polyimide low dielectric/low dielectric loss tangent adhesive film is a thermosetting film adhesive suitable for Next-generation high-speed/high-frequency telecommunication applications.
Features
- Polyimide resin design achieves a dielectric loss tangent of 0.006 at 20 GHz.
- In addition to high heat resistance, it also achieves high strength and high elasticity.
- Can be provided at thicknesses up to 400 µm.
Applications/Usage
FALDA™ polyimide low dielectric/low dielectric loss tangent adhesive film has a cover film on both surfaces and supports laser via processing.
