The method includes steps of providing an acoustic wave filter die having an active area disposed on a first surface thereof, providing a leadframe including a die flag and sealing the first surface to the die flag. The method also includes steps of molding a plastic package body about the die and the die flag and singulating the plastic body, the die and the die flag. The molding step desirably includes substeps of placing the acoustic wave filter die sealed to the leadframe in a mold, applying a thermosetting plastic material at a suitable temperature less than the glass transition temperature and at a suitable pressure to the acoustic wave filter die sealed to the leadframe in the mold and maintaining the suitable temperature for a suitable period of time.
