Automated lead wire tinning apparatus mechanical adjustments and improvements

摘要

Apparatus for automatically tinning leads of components mounted on tapes to carry the components through solder wave stations have adjustments incorporated to permit tinning components of different sizes. Foam generators with independent foam rate adjustments are also provided to permit the adjusting foam height separately for each component lead. Guards are used with the foam generators to select specific segments of each lead for fluxing. A vacuum port with a vertical heated connection leading to a vertically oriented heated collector insures that excess solder will not clog the collection systrem. A shield between the vacuum port and the solder wave prevents solder being ingested by the port.
