Abstract: 1,013,417. Cold pressure-welding; making punches. SIEMENS & HALSKE A.G. Aug. 28, 1964 [Aug. 29, 1963], No. 35264/64. Headings B3A and B3R. A tool, for use in attaching electrical connection wires to electrodes of semi-conductor systems consists of a punch having an axial bore through which the wire passes and projects from one axial end thereof, by which end the wire is compressed against the electrode to which it is to be attached, and is characterized in that the punch is composed -of two parts which mate in a plane parallel to the punch axis, are united and between their mating surfaces define the punch of the bore. A tool for use with a gold wire 3 of about 13 microns diameter which is to be attached to an electrode 2 of a semi-conductor 1, comprises a part 4 having a rounded tip 4<SP>1</SP> that is used to press the wire against the electrode 2, and a part 5 which has a groove along its length. The parts 4, 5 are joined by welding, soldering or other known means. The groove is formed in the part 5 by grinding with a tungsten wire of 15-18 microns which is coated with diamond dust of particle size about 1 micron, until the depth of the groove is equal to the wire diameter. The part 5 is made of brass, stainless steel, or hardened steel, and the part 4 of hardened steel or ruby. Alternatively, the groove can be ground into the part 4 and a plane surface provided on the part 5, or both parts may be formed with grooves and co-operate to form the bore 6. In a modification, the bore groove 6 is produced by pressing a tungsten wire into the part 5, by means of a flat punch, a process which facilitates the provision of a funnel-shaped end to the groove at the end remote from the operating tip 4<SP>1</SP>, by a second step using a thicker conicallytapered wire. In a second modification the groove is formed by a punch having a prismatic cross-section enclosing an angle of 120 degrees, so that the cross-section of the bore 6 is an equilateral triangle. In this modification, the inscribed circle of the triangle is greater than the wire diameter.
