Method and apparatus for mounting electronic components |
摘要 |
Trays within a tray feeder provided with electronic components requiring a higher accuracy of mounting position such as QFPs, etc. are collectively placed at one side of a recognition device equipped with a line sensor. A transfer head picks up an electronic component in the tray and discerns a position of the electronic component by moving over the line sensor in one and the same fixed direction at all the time. This scanning direction is the same as a direction of calibration of a nozzle of the transfer head. Accordingly, a detecting error in the position of electronic component caused by the scanning direction is eliminated and the electronic component can be mounted with a high positional accuracy on a substrate.
