Abstract: The invention is directed to a method and apparatus for selectively and simultaneously drilling a plurality of holes in thin panels such as printed circuit boards, while providing for automatic changing of the drill bits, individually or plurally, as required. A tray of drill bits is driveable in X and a row of vacuum pickers are driveable in Y, so that the various bit locations of the tray are addressable by such X-Y positioning, and selectable vacuum pickers are extensible and retractable so as to pick and place the drill bits at various matrix locations of the tray. The vacuum pickers also are extensible and retractable through corresponding tray openings in order to deliver replacement bits to, and retrieve used bits from, a flipper assembly associated with each drilling module.
