Abstract: A lead frame assembly of indefinite length having a pair of spaced parallel carrier strips, collapsible rungs extending between the strips at regular intervals along the length of the assembly and a number of leads extending inwardly from the opposed edges of the strip between the rungs. The rungs are collapsed inwardly to seat the ends of the leads against the sides of circuit modules previously positioned between the ends of the leads. The lead ends are seated in recesses in the circuit modules and are subsequently soldered to metalized surfaces on the modules. Following the bending of the leads, the carrier strips and rungs are cut away.

Abstract: Apparatus for manufacturing dual in-line packages from a single continuous lead frame assembly and a number of leadless circuit modules. The apparatus includes a loading station where modules are positioned in spaces in the lead frame assembly, a closing station where leads carried by spaced carrier strips on both sides of the modules are moved toward the modules to engage the modules adjacent metalized pads and to collapse interconnecting rungs, a soldering station where the leads are soldered to the pads, a bending station where the leads are bent down with respect to the module through about 90 degrees, a cut off station for removing the carrier strips on either side of the lead frame assembly, and associated drives for moving the lead frame assembly past the various stations.
