ABSTRACT:
A position detection system is provided which, without physical contact, by the use of detected infrared energy emissions determines whether there is correct placement of one or more small objects, e.g., lead frames, on the lower half of a two-part die mold in a semiconductor component manufacturing process. This takes place prior to injection of an initially molten material that solidifies and encapsulates the small objects upon curing and cooling.
