The "Head" tab sheet is provided with the following 2 tabs. When

each tab is pressed, the corresponding tab sheet appears.

Tabs Description

Head Center Offset The corresponding tab sheet enables the operator to set the deviation

in the distance between the scanning coordinate center of the P.E.C.

camera and the head rotational center.

Head Offset This offset data is used to correct the positional deviation (placement

coordinates) caused due to the deviation of straightness (skew) of

each individual head up/down axis guides.

The set parameters are added to the amount of beam movement

(travel) for component placement.

*1 Offset Items

Set the following offset values.

Head 1 Nozzle 1 through 6

X [mm] (Horizontal) and Y [mm] (Vertical)

The NC axis is rotated such that a nozzle on Head #1 is specified

as Nozzle #1.

This offset data is used to set the distance between the scanning

coordinate center (actual position) of the P.E.C. camera on the beam

and the rotational center of Head #1 (Nozzle #1). The distances

deviating from the design values must be entered in each text box.

The parameters must be those viewed in the coordinate system

(PL-XY) for P.C.B. positioning.

As for Nozzles #2 through #6, the offset data is set in the same way

as Nozzle #1.

When the rotational center of Head #1 is actually located at the po-

sition shown in Fig. 3E34, the offset parameters representing the X

(horizontal) must be provided with a minus (-) sign and the offset

parameter representing the Y (vertical) with a plus (+) sign.

This offset data is calculated through teaching operation which is

performed, using the jig component stationed at the teaching plate

inside the machine.
