Patent ID: 7020956

Claim:
A component mounting method comprising: performing an operation for detecting an occurrence of a lack of a component at a designated component arrangement position of a component feed part, from which designated component arrangement position the component was to have been supplied so as to have been mounted onto a printed circuit board, by a mounting head that is to mount components onto the printed circuit board in an order based on a mounting program, in accordance with a mounting cycle time based on the mounting program, wherein the component and the designated component arrangement position are designated by the mounting program; when the occurrence of the lack of the component at the designated component arrangement position is detected, switching supply of the component from said designated component arrangement position to supply of a spare component from a component arrangement position other than said designated component arrangement position; and then determining a mounting order in conformity with a component feed state for said spare component so as to not detrimentally increase the mounting cycle time by reorganizing, the order in which components are to be mounted onto the printed circuit board by said mounting head such that a distance that said mounting head is to move during mounting of the components onto the printed circuit board decreases, and thereby re-generating the mounting program.
