Abstract
<PICT:1016352/C1/1> <PICT:1016352/C1/2> In a method of manufacturing a base plate for electrical circuit elements, a plurality of current supply wires 4, Fig. 1, for the elements are initially sealed into a bead 10 of insulating material, which is then softened by heating and pulled into a mould 1 by longitudinal movement of the wires which are guided by bores 3 in the mould. In the event of the base plate having an irregular surface as shown in Fig. 7, one of the wires 28 may be moved more than the others. Prior to heating by burners 9 the bead may be located in the mould and heated sufficiently to attach it to one of the wires, after which it is withdrawn to complete the heating process. The wires 4 may support a transistor which is enclosed in a dome-shaped glass envelope which is hermetically sealed to the base plate.
