6.5.1 Introduction For 6.5 Testing Jobs (Nxt V3.10 And Higher) Of 6. Editing Jobs On The Machine on FUJI NXT

FUJI_NXT Scalable SMT Placement Platform

The job test function enables users to view and edit jobs on the machine prior to starting production. By doing this, errors that occur during the beginning of production for a new job can be greatly reduced. There are two job test modes and the items checked by each mode are different. Information about these two modes are provided below.

Simulation

The placement position for a specified sequence is captured using the mark camera and the panel pattern is compared graphically with the part image (wire frame) in MEdit.

This allows the operator to check for any placement position deviations and problems with the placing angle. In addition, it is possible to confirm that the part type is roughly correct by comparing the wire frame of the part graphic to the actual pad arrangement. If there are any calculated placing deviations, they can be corrected easily in MEdit and be reflected back to the job.

The main items checked by this mode are fiducials, placement position, orientation, and part types compared to the pads. Actual parts are not required to perform this test, just an actual panel is required. If any problems with these items are located, corrections can be made and checked again.

Place & Check

Parts are picked, vision processed and placed on the panel. Once a part is placed, the mark camera takes an image of the position and that image is then displayed in MEdit with a part graphic overlay in MEdit.

This allows the operator to check for pickup errors, vision errors, actual placement position deviations and problems with the placing angle. If there are any errors, they can be corrected in MEdit and be reflected back to the job.

The main items checked by this mode are fiducials, feeding, feeding direction, vision data, placing data, actual placement position, and orientation. Actual parts are required to perform this test as well as an actual panel. If any problems with these items are located, corrections can be made and checked again.
