ABSTRACT:
An automatic soldering machine and method for soldering the ends of pretinned components such as ceramic chip capacitors, transistors and the like, while leaving one side of the component flat, is disclosed. The components are supplied by a vibratory feeder to a pick-up station where they are sequentially picked up by a vacuum probe and are transferred to a print station where a retaining mechanism comprising a spring biased finger and a metal plate retains the component. A plurality of these retaining mechanisms are secured to an indexing table which passes in succession a printing station, a preheating station, a soldering station and a take-off station. At the soldering station a predetermined amount of solder is fed to the ends of the components and a heat lamp is flashed to melt the solder.
