Abstract
A conveyor 21 rapidly advances a series of workholders to move printed circuit board connectors 10 mounted therein along a short insulating rail section 37 and a second long cooled rail 31. Presoldered leads 13 overlaying contacts pads 14 are heated to temperatures slightly above the melting point of solder during movement along the first rail 28 and are cooled to solidify the solder during movement along the second rail. A belt 44, moving at the same speed as the conveyor, presses the boards to ensure good contact of the leads with the pads during the melting and cooling of the solder.
