Ablefilm Sheet 5025e

At NEDC we die-cut and laser-cut many types of adhesives. One adhesive that stands apart is Ablefilm® 5025E™. This film is one of the most common converted at NEDC via laser-cutting or die-cutting. 5025E is an unsupported electrically/thermally conductive epoxy film that is used for bonding circuit boards to heat-sinks or other components. The epoxy film is used as a binder to hold the silver particles in place. The silver particles imparts its high level of electrical (X,Y, Z directions) conductivity. As a demonstration of this films high level of electrical conductivity, its volume resistivity reaches lower than .0005 ohms/cm.

Uses and Benefits of Ablefilm® 5025E™

-Thin Uniform Bondline

-Providing EMI/RFI shielding

-Great thermal and electrical conductivity

-Quick cleanup/Easy of assembly
