Abstract(in English) | This paper describes a new joining method of a copper sheet to metal pillars (copper bumps) and its experimental results. The pillars are put in holes of a thin insulator and near the sheet. When an impulse current from a capacitor bank passes through a flat one-turn coil, a magnetic flux is suddenly generated around the coil. Eddy currents are induced in the sheet placed between the coil and the insulator. Electromagnetic force acts on the sheet. The sheet can be welded to the pillers both by the Joule heat and by the high-speed collision to the pillers. The bank energy required for this welding is less than 2 kJ. |
