ABSTRACT:
A mounting coordinate input method and apparatus images a printed circuit board on which a surface mount device is mounted and edits a coordinate and component information necessary to mount the surface mount device on the PCB to produce a mounting information to be inputted to surface mount device equipment. In the method, an image of a printed circuit board is taken. Component information of the surface mount device to be mounted on the printed circuit board at an arbitrary angle is inputted to display a surface mount device mark printed on the printed circuit board corresponding to the component information. Coordinates of first and second reference corners of the surface mount device mark is set and center coordinates of the surface mount device mark is calculated. A reference rectangle of the surface mount device mark is displayed. An arbitrary angle set mode with the surface mount device is selected to display a fan including a predetermined angle formed by a first side defining a straight line between the first reference corner of the surface mount device mark and a cursor on a screen and a second side defining a straight line between the first reference corner and an X-axis on the screen. The predetermined angle of the fan which allows the first side of the fan to coincide with a side of the surface mount device mark is control to set the controlled angle of the fan as the arbitrary angle of the surface mount device.
