An integrated circuit chip carrier assembly is provided by joining a substrate having electrically conductive regions on at least one major surface thereof to a stiffener by a bonding film. The bonding film comprises a dielectric substrate having a thermoset adhesive on both of its major surfaces. The thermoset adhesive prior to the bonding is a B-stage adhesive, is tack-free at normal room temperatures and is solvent free. |
