Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes a new welding technique for copper foils on
flexible printed circuit boards and its experimental results. When an
impulse current from a capacitor bank passes through a flat one-turn
coil, a magnetic flux is suddenly generated in the coil. Eddy currents
are induced in overlapped copper foils on the boards placed on an
insulated aluminum sheet and the coil. The foils have a gap between
them. The foils can be welded both by the Joule heat generated in them
and by the impact effect with pulsed magnetic pressure applied to them.
The bank energy required for this welding is less than 1.2 kJ.
