This company’s 5025E adhesive film provides excellent electrical and thermal conductivity in microwave and heat-sink applications. A silver-filled, unsupported epoxy, 5025E adhesive film is electrically conductive in the x, y and z axes. The product’s high level of thermal conductivity allows for the bonding of “hot” components onto heat sinks in applications that do not require electrical insulation. When used to bond microwave substrates into packages, the film provides RF/EMI shielding. 5025E is available in die-cut preforms, as well as sheet stock.
