Abstract
A soldering machine for simultaneously applying liquid solder to opposite sides of the leads of a lead frame having I.C. devices thereon. The machine has sidewardly spaced roller assemblies which define a vertically extending narrow nip therebetween through which the lead frame assemblies pass. A solder bath is disposed below the roller assemblies so that lower portions of the rollers dip into the bath and carry a solder film to the nip for application to opposite sides of the leads. A passage extends upwardly in isolation from the bath for permitting the lead frame to be fed vertically upwardly into and through the nip.
