Abstract

1453923 Soldering ILLINOIS TOOL WORKS Inc 3 July 1975 27960/75 Heading B3R [Also in Division B6] In a method for applying solder to contact points (e.g. pretinned ends of a ceramic chip capacitor) of an electrical component 16 having a flat surface 74, a retaining finger 50 biased by a spring 48 presses the component 16 on to a solder-rejecting flat metal plate 40 (the plate 40 and finger 50 preferably of Ti) such that no solder will penetrate between the plate 40 and the flat surface 74. An automatic indexed rotary table 12 has a plurality of the plates 40 around its periphery, its operation being as follows. The component 16 is transferred by a pivotable vacuum probe 22 from a pick up station 20, adjacent a vibratory feeder 18 to a vacuum holding platform 55 from where a pusher member 56 pushes it between the spring biased finger 59 and the plate 40, the spring being neutralized by a lever 51 (Fig. 10). While on the platform 55 an identifying indicia is applied by a pivotable printing element 260 (Fig. 10). As the table 12 rotates in the direction of arrow 64 the components pass through a preheater 76 before tubes of solder 88, 90 are fed by air driven and idle rollers 92, 94 over the ends of 102, 104 of the components 16. A flash lamp 110, adjacent the rollers 92, 94, melts the solder over the end. The soldered components are removed by an unloading arm 118 with the assistance of a lever similar to the lever 51. A cam controlled indexing device is disclosed for the automatic control of the operational sequence.
