A system, including a method and cognate apparatus, places an object on a carrier with great accuracy. Three prepositioned pins on a holder engage a corner portion of the carrier formed between adjacent side edges of the carrier to provide the corner in a predetermined fixed relation to the stops. Two prepositioned spaced target points at predetermined locations on the object are aligned in a predetermined orientation with the pins and thus with the adjacent side edges of the carrier, enabling the object to be placed on the carrier in precise manner. A sensing and placing mechanism, such as a camera, vision system and micropositioning table, senses the pin positions on the holder and target point positions on the object. The object is placed on the carrier in dependence upon the sensed pin and target point positions such that each target point is in a preselected position relative to the pins and pin engaged corner of the carrier.
