摘要：
A component supply tape (2) is stepped to present each pocket (10) at a component pick-up area, and a top cover of the tape (2) is peeled back so that each pocket (10) is opened in turn. A shutter (66) is positioned over the pick-up area prior to tape movement so that the pocket (10) is covered by the shutter (66) as the top cover (6) is peeled from the substrate. After each indexing step, the shutter (66) is actuated to uncover the opened pocket (10) which is situated at the pick-up area for retrieval by the vacuum nozzle (30) of a pick-and-place head. By the improved method and apparatus of the instant invention, the pick-and-place head is provided with a finger for opening the shutter (66) of the feeder while the vacuum nozzle (30) is advanced along a normal to the pick-up surface of the component (20), so as to minimize the period of time that the component (20) is uncovered.
