Patent ID: 7591068

Claim:
A component mounting method for a mounter including at least two mounting stages in which components are mounted onto boards transported from the upstream side in a transportation direction of the boards and then the boards are transported to the downstream side, said method comprising: stopping a first edge of a first board on a first mounting stage; stopping a second edge of a second board on a second mounting stage such that the second edge of the second board faces the first edge of the first board, the second mounting stage being on a downstream side of the mounter relative to the first mounting stage; obtaining position data on a first origin, the first origin being a reference position for coordinates of mounting points; obtaining position data on a second origin, the second origin showing a position of a stopping unit of the first mounting stage; obtaining position data on a third origin, the third origin showing a position of a stopping unit of the second mounting stage; converting the coordinates of the mounting points into first converted coordinates using the second origin as a reference; mounting a component onto the first board stopped on the first mounting stage based on the first converted coordinates; converting the coordinates of the mounting points into second converted coordinates using the third origin as a reference; and mounting a component onto the second board stopped on the second mounting stage based on the second converted coordinates.
