Calibration
The MCDATA (Production program) is contained in the DVD-ROM (Machine system /Recognition / LNB
system disk) that comes with the machine.
Refer to the MCDATA sheet included in the DVD-ROM, select the target MCDATA according to the machine
type. Copy it to an SD card once and load it to the machine.
An SD card should be prepared by the customer.
If you overwrite the MCDATA downloaded to the machine to the SD card, the MCDATA in the SD card will not
be functioned. If you accidentally overwrite to the SD card, copy the data from DVD-ROM again.
If you must perform accuracy verification by the configuration which is not in the MCDATA list such as head
change, please contact us.

Accuracy verification
Explains considerations for accuracy verification.
■MCDATA type
MCDATA (production program) is exclusively used for accuracy verifications.
There are the following two types of MCDATA used for inspection accuracy verifications.
Offset Refection MCDATA
*The one with “TSEIDO” included
in its data name
The inspection head inspects a circle of 2mm diameter on the plane
calibration jig and measures a displacement amount between the
design coordinates and the actual coordinates.
It is used when inspection camera offset acquired from the measured
result is reflected to the inspection head.
Accuracy Verification MCDATA
*The one with “SKEN” included in
its data name
The inspection head inspects the part patterns on the plane calibration
jig and measures a displacement amount between the design
coordinates and the actual coordinates.

Brief description of process
This section describes the procedures for measuring the inspection head accuracy and updating the
inspection camera offset by using the measured result. The plane correction jig is used for
measurement.
●Because the plane correction jig is inserted and taken out from the upstream process, adjust the
width of the upstream transfer conveyor to that of the plane correction jig.
The dedicated MCDATA (production
program) is used for inspection head
accuracy verification and registering the
inspection camera offset. When the
inspection camera offset is reflected,
machine parameters in the machine will
be rewritten.
●You are recommended to save the
current data beforehand just in case.
(→[Operating procedure] P.2-3-4)
MCDATA (production program)
●There are two inspection head types: 18 μm and 9 μm.
●If the inspection head is attached, the supply unit is only on the rear side.
Front: Inspection BOX(I)
Rear: Tape feeder (F), single tray feeder (FT)
*1)
or twin tray feeder (TT)
● In the head pattern, for example, 9I-8F shows the front: 9 μm inspection head, the rear: 8- nozzle head,
and the tape feeder supply section.
Likewise, 18I-3FT shows the front: 18 μm inspection head, the rear: 3- nozzle head, and the single tray
feeder supply section
