Abstract:
1. A semiconductor chip mounting apparatus comprising: a semiconductor chip supply unit to supply a semiconductor chip; a mounting member carrier unit to carry a mounting member; a semiconductor chip carrier unit to carry out mounting operations, wherein said mounting operations include picking up said semiconductor chip from said semiconductor chip supply unit, carrying said semiconductor chip to a mounting position of said mounting member, and mounting said semiconductor chip on said mounting position of said semiconductor chip carrier unit; a sensor unit to measure first and second positions of said semiconductor chip carrier unit before and during said mounting operations, respectively, wherein said sensor unit measures said second position of said semiconductor chip carrier unit when said semiconductor chip carrier unit carries out semiconductor chip mounting operations at predetermined times; a control unit to calculate position deviations of said first position of said semiconductor chip carrier unit from said second position of said semiconductor chip carrier unit to provide position adjustment instructions when said position deviations are greater than a predetermined value; and an adjustment unit configured to adjust said second position of said semiconductor chip carrier unit in response to said position adjustment instructions of said control unit.
