摘要: A method of enhancing the heat dissipating properties a rigid substrate plate through creation an array erect spaced-apart parallelly disposed metallic fins projecting from surface plate. The are created by superimposing sheet foil upon plate, with being bonded to welding utilizing ultrasonic energy. welds formed as parallel bands, slit adjacent one edge band, thereafter folded outwardly form fins. folding operation is undertaken following steps populating substrate, thereby eliminating requirement for unusual or precautions protect what otherwise would be extending
