Abstract

An apparatus for cutting tie bars of semiconductor packages unloads the semiconductor packages by continuously blowing air against the side of the packages after the tie bars are cut and the semiconductor packages are separated from lead frames. The packages are blown into a guide track which feeds into a storage tube. As a result, damage to the packages due to mechanical abrasion which may result from unloading with a pusher bar is prevented. Furthermore, the time required for unloading the semiconductor packages is reduced.
