An apparatus including a pick-and-place apparatus and methods of operating a pick-and-place apparatus. The pick-and-place apparatus includes a frame, a plurality of vacuum rails movable in the frame, a row of vacuum nozzles on each vacuum rail, a plurality of stop members, a first mechanism for biasing the vacuum rails apart, toward, and into engagement with the stop members, and a second mechanism for biasing the vacuum rails together. The vacuum rails have a maximum pitch, in which the vacuum rails are biased apart by the first mechanism and engage the stop members, and a minimum pitch, in which the second mechanism overcomes the bias of the first mechanism and biases the vacuum rails together. The pick-and-place apparatus can pick up a two dimensional array of electrical parts, change spacing between the electrical parts, rotate the two-dimension array of electrical parts and place the parts in carrier tape. |
