Abstract: An electric device includes: a housing; a plurality of conductive leads provided on the housing; at least one coil unit disposed in the housing, electrically connected to the conductive leads, and including a core and an enameled wire wound around the core; and a heat insulator disposed in the housing and covering at least one side of the coil unit. A method for producing an electric device includes the steps of: providing a housing confining an inner space therein and provided with a plurality of conductive leads thereon; disposing at least one coil unit in the inner space of the housing, and electrically connecting the coil unit to the conductive leads, the coil unit having a core and an enamelled wire wound around the core; and mounting a heat insulator in the inner space of the housing for covering one side of the coil unit.

Abstract: A SAW device includes: a SAW chip having a piezoelectric substrate and transmitting and receiving transducers; a circuit board formed with conductive inner contacts, each of which is connected electrically to a respective one of the transmitting and receiving transducers; a first adhesive-confining curb interconnecting the circuit board and the transmitting and receiving transducers and cooperating with the circuit board and the SAW chip to define an enclosed cavity thereamong; a second adhesive-confining curb surrounding the first adhesive-confining curb to define a sealing space therebetween; an adhesive body filling the sealing space; and a molding compound covering the SAW chip and connected sealingly to the second adhesive-confining curb.
