ABSTRACT:
Positioning recognition marks are read by movable recognition device for positioning objects to be bonded to each other. An alignment method includes a step of reading the recognition marks during movement of the recognition device before its complete stop, and a step of identifying absolute positions of the recognition marks by correcting the mark recognition positions having been read based on a position feedback signal of the moving recognition device. A mounting method using the alignment method is also disclosed. It is possible to maintain a high alignment accuracy, eliminate necessity of assuring a settling time for complete stop of the movable recognition device, and significantly reduce the alignment time and mounting tact.
