4.12.2 Bad Mark Sensor Offset Select "2/Offset set-up" then "4/Head", "2/Bad Mark Offset" and the bad mark offset setting dialog will appear as follows. (1) Setting Items No. Item Contents 1…
Set CAL piece A on CAL block.
For LA or LAHD setting head use #106 nozzle and for LAIC head use #203 nozzle.
Once ready, select "OK".
When "OK" is selected, offset is measured.
– Content of Measurements
(1) Turn on CAL block vacuum to initialize suction.
(2) Once OCC recognizes the position of the piece, concentricity and gradient are calculated.
If both of the holes in the piece are not recognized, error will occur.
If error occurs, verify piece position.
(3) Head takes piece with suction and CAL block vacuum shuts off.
(4) Piece is recognized by laser.
(5) From piece gradient calculations in (2) and laser recognition values in (4), laser
assembling angle and head assembling position are calculated and modifications made.
(6) OCC recognizes CAL block position and concentricity & gradient are calculated.
(7) Piece is mounted in center of CAL block, CAL block vacuum turns on and holds piece. At
this time, the calculated piece gradient from (2), the calculated laser assembling angle
and assembling position from (5) and the calculated CAL block gradient are corrected for
and the piece is mounted.
(8) To verify mounting position, OCC checks piece position.
If the recognized center of gravity between the monitor cross cursor and mark becomes
skewed at this time, repeat automatic measurement.
Remove nozzle from setting head.
Remove CAL piece A from CAL block.
When completed, select "OK".
Setting is completed.
Select "OK" to return to default operation screen.

4.12.2 Bad Mark Sensor Offset
Select "2/Offset set-up" then "4/Head", "2/Bad Mark Offset" and the bad mark offset setting dialog
will appear as follows.
(1) Setting Items
No. Item Contents
1 Assembling Position Offset value for setting position of each head (OCC std)
(2) Method of Setting
– Enter values directly with the keyboard or follow the internal operating instructions for
automatic input.
– Select HOD device key to enter teaching.
– Use control menu to move head if in the way.
– Operating method of automatic input
Follow instructions to operate and values will automatically acquire.
Once completed, select "OK".
When "OK" is selected, bad mark sensor moves to above CAL block No. 1 mark.

With teaching closely align sensor beam with CAL block No. 1 mark. Move unit to turn sensor off
and press HOD entry key.
Once completed, select "OK".
When "OK" is selected, bad mark sensor measures CAL block No. 1 mark position.
– Contents of Measurement
(1) Scanning from default position in +X direction, position is measured when sensor turns
ON.
(2) Scanning from default position in -X direction, position is measured when sensor turns
ON.
(3) Based on position calculations in (1) & (2), X direction center of the No. 1 mark is
calculated.
(4) Y direction is measured the same as X. Y direction center of the No. 1 mark is
calculated.
(5) From the center position for the No. 1 mark calculated in (3) & (4) and the known CAL
block No. 1 mark position, fixing position is calculated and modifications made.
Setting is completed.
Select "OK" to return to default operation screen.
Once completed, select "OK".
When "OK" is selected, offset is measured.
