Abstract

The existing feed tracks, into which wing leaded surface mounted devices (SMDs) are fed manually by hand, permit excessive tolerances between the SMD's leaded edge and the edge of the trac the SMDs pick-up position. Thus, in a pick and place operation, this excessive tolerance requires that the SMD's be mechanically centered after pick-up with the machine's tweezer jaws. However, experience has shown that the centering effort is ineffective when attempted against the SMD's protruding leads.
