BEAM B HEAD #2, X (Horizontal), Y (Vertical)
This offset data is used to set the distance between the scan-
ning coordinate center (actual position) of the P.E.C. camera
on Beam B and the rotational center of Head #2. The distances
deviating from the design values must be entered in each data
box.
The parameters must be those viewed in the X/Y coordinate
system (PL-XY) for P.C.B. positioning.
• Design Values (distances between the center of P.E.C. cam-
era on Beam B and the rotational center of Head #2)
X : +54.000 mm
Y : +0.000 mm
When the rotational center of Head #2 is actually located at
the position shown in the figure below, the offset param-
eters representing the X (horizontal) and Y (vertical) must
be provided with plus (+) signs.

This offset data is automatically calculated through teaching
operation which is performed, using the jig component sta-
tioned at the teaching plate inside the machine.

BEAM-A NOZZLE STOCKER [A1]
The set offset data is used to adjust the positional deviations based on the
design dimensions representing the nozzle stocker unit position viewed from
the X/Y coordinate system (PL-XY: Origin P0) for P.C.B. positioning.
The values based on the PL-XY coordinate system must be entered in the
data boxes.
Set the values which represent the positional deviations of Nozzle Stocker
A1 based on Beam A.
X (Horizontal) and Y (Vertical)
When offset parameters are set with a plus (+) sign, the nozzle change
directions are changed to “X (+)” and “Y (+)” shown in the figure.

LEVEL (Height)
When an offset parameter is set with a plus (+) sign, the nozzle change
direction is changed to “L (+)” shown in the figure, concluding that the
descending stroke has increased.
SET LVL
Set an offset value (offset in vertical (height) direction of the head) re-
quired when a nozzle is attached to the head.
(This is added to the parameter in the “LEVEL (Height)” data box.)
When an offset parameter is set with a plus (+) sign, the up/down shaft
descends, concluding that the descending stroke has increased.
RESET LVL
Set an offset value (offset in vertical (height) direction of the head) re-
quired when the nozzle is stored.
(This is added to the parameter in the “LEVEL (Height)” data box.)
When an offset parameter is set with a plus (+) sign, the up/down shaft
descends, concluding that the descending stroke has increased.
Note: As for the values to be set in the “X” and “Y” data boxes, align the
nozzle position manually at several places (1 through 10) and per-
form the measurement. Then, set the mean values in each data box.
When the nozzle is manually aligned only at one place, it may be
positioned at a place where the nozzle cannot be changed easily.
