Abstract

1502965 Welding by pressure; welding electrical contact PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 16 May 1975 [21 May 1974] 20840/75 Headings B3R and B3A In a method of welding a wire 9 (e.g. gold) to a semi-conductor body 1, an electric spark discharge between an electrode 10 and the end of the wire 9 melts the wire to form a ball 11 below a recess 8 in the welding surface 6 of a welding tool 5, preferably an ultrasonic sonotrode, whereupon the tool 5 presses the ball 11 on to a contact place 2 of the semi-conductor body 1 to produce the weld. The welding tool 5 also produces a weld between the wire 9 and a supply conductor, without the formation of a ball 11 (Fig. 6, not shown). The electric spark discharge may be provided by way of a transformer fed by a discharge capacitor, the discharge time being less than 5 msec. and the energy of the discharge (hence the size of the ball) determined by the capacitor voltage. The recess 8 can either be a groove transverse to the wire 9, which is fed to the welding surface by way of a hole in a separate plate (not shown) or an aperture 7 in the welding tool, or a cone having an apex of 120 degrees. On completion of the weld to the supply conduction the tool remains in its welding position as the wire is snapped by pulling.
