Abstract:
Electronic component mounting method for mounting an electronic component on a plurality of board types includes: placing, on tray holding shelves, trays storing components for first and second board types, respectively; recognizing on which tray holding shelf the tray is placed by reading identification information from the trays. The method further includes: rearranging the trays in the tray feeder to a first tray arrangement adapted for the first board type, based on recognized placement position of the tray and the first tray arrangement data, before start of production of the board of the first board type; and rearranging the trays in the tray feeder to a second tray arrangement adapted for the second board type, based on the second tray arrangement data, before start of production of the board of the second board type.
