Product Description
LOCTITE ABLESTIK ECF 506 is a flexible, gray heat-cure epoxy film adhesive with a glass-fabric carrier for bonding materials with mismatched coefficients of thermal expansion in electronic assemblies. Typical cured properties include thermal conductivity of 1.0 W/(m K) at 121 deg C, electrical resistance of 0.005 ohm/0.5 sq in measured through joints, and aluminum-to-aluminum lap-shear strength of 1,000 psi at 25 deg C. Typical work life is 24 hours at 25 deg C. Recommended cure is 1 hour at 150 deg C, with alternatives of 1.5 hours at 125 deg C or 3 hours at 100 deg C. Bonded components can be reworked by heating the component to 125 deg C and sliding a thin blade between the bonded surfaces.
Key features
- Glass-fabric bondline control: A glass-fabric carrier is combined with the film's specified uniform bondline-control characteristic.
- 24-hour work life: Typical work life is 24 hours at 25 deg C.
- 125 deg C thermal rework: Bonded components may be heated to 125 deg C and separated with a thin blade.
Applications
Electronic assembly bonding of materials with mismatched coefficients of thermal expansion.
