Automated convection soldering
The object of this work was to determine the feasibility of convection soldering and process control through automation of the solder process. Convection heating proved feasible for male connectors with no detrimental effects to the connector insulation. Full automation of the soldering process using programmable x-y-z tables and a solder paste dispensing system was achieved for flat flex cables. There were a number of advantages gained by using an automated soldering process. The soldering used for reflowing a joint was eliminated, eliminating possible cold solder joint formation. The size of the flux inclusions in the bottom of the solder cup caused by a temperature gradient on the cup when heat was applied was reduced. There was better control of the soldering time and temperature and the quantity of flux and solder added to each joint. The study became a starting point for the incorporation of new technologies and processes. 1 ref., 27 figs., 2 tabs.
