A method for forming electronic assemblies includes providing a plurality of IC die each having IC bonding conductors and a workpiece having workpiece bonding conductors. A curable dielectric film is applied to the IC bonding conductors or the workpiece surface. The plurality of IC die are placed on the workpiece surface so that the plurality of IC bonding conductors are aligned to and face the plurality of workpiece bonding conductors to provide a first bonding.
