6.2.4 Adjusting the Tool for the Dual Strip and Small Boards in
Combination with the Carrier Kit.
The dual strip is a strip for small boards. To mount it on a board only the fixed slide
is used to put the dual strip on. Follow the standard procedure and instead of two
strips only the dual strip is used.
The combination Carrier kit and small production boards (87.0mm to 101.5mm in Y)
can cause interference of the calibration strips with the reference pin. Therefor the
rear (north) strip should be placed lower then 23mm from the rear edge. A default
value can be 52.5mm from the edge (checkbox “fixed alternatives” checked gives
automatically the right value).
The offline preparation tool has this value also:
Use the adjustable slide and the support slide as one slide: push the support slide
against the adjustable slide and move it as one slide to fit in the production board.
Put the calibration strip on the support slide instead of on the adjustable slide. The
strip is mounted 52.5 mm from the rear edge.
6.2.5 Calibrating with Alternative Strip Positions
FIGURE 6-5
The FCM assumes that during Multiflex calibration the calibration strips are on
23mm from the edge of the board. If the strips are mounted on other positions
these positions must be mentioned to the FCM. This can be done in the “Cali-
bration” dialog.

6.2.6 Alternative Reference Pin Position
Multiflex calibration uses the reference pin (also known as temperature pin) in its
process. Therefor the FCM needs to know where this pin is located. In x-direction
the software can calculate (from board size and board pitch) the reference pin
position. However the y-position of the reference pin position is dependent of the
carrier type used.
IMPORTANT: In the action spec the correct values should be stated.

TABLE 6-2
If the reference pin position in the action spec is incorrect or missing the correct
values can be entered in the “Calibration” screen. Entering the position via this
screen has the disadvantage that the value in the action spec is not updated. This
means that reuse of the action spec always requires calibration.
The calibration dialog:
The Y-postion of the reference pin w.r.t. the south edged of the board according to
the values in the action spec. These values can be edited by checking the
checkboxes under ‘reference pin position’. Default value: 36 mm.
