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.
