2.1.3.1 Measurement plates
The measurement plate (Calibration board single kit 03056448-01) is a glass board (300 x 200 x
4 mm) on which a chrome structure has been applied on one side.
This glass board is glued inside an aluminum frame using silicon.
Knurled bolt
The cover is fixed to the
board frame using a
knurled bolt.
• Unscrew bolt.
Mounting
braket
On the other side (opposite the
bolt fixing), the cover is held in
place only by the mounting brack-
et.
• Raise the cover slightly on this
side.
• Next, push cover to left while
holding the board in the frame.

• On the underside, the glass board is protected
by a thin metal plate.
It is known as the "reflective" plate since it can
be used as a background for reflective meas-
urements.
• The reflective plate slides lengthways into a groove
below the glass plate.
• There is a stop on one of the side edges of the
frame to prevent the reflective plate passing right
through.
• If the reflective plate is pressed against the stop then
the 4mm hole in the reflective plate coincides exactly
with the threaded hole for the knurled-head bolt. As a
result, when the knurled bolt is screwed in, it stops the
reflective plate moving.
On the one hand, the plastic strips on the inside of the
cover help seal the top of the glass board against dust.
On the other, they provide a safety margin to prevent the
cover from touching the spray adhesive on the glass board.
• To pack the board again, place the glass board on a flat
surface (table) after introducing the reflective plate.
• Next place the cover straight over the glass board and
then push it from left to right in order to move the mount-
ing bracket (see above) under the frame.
• You can now screw in the knurled-head bolt.
• However, do not screw it in fully. Instead after about half
a turn, lift the complete plate and press the reflective
plate at the bottom against the stop and then tighten the
knurled-head bolt.

NOTICE
2TImprove Contrast when measuring fiducials
To improve contrast when measuring fiducials in the placement unit, the reflective plate can be inserted for
each placement.
Global fiducials (cross) for centering in place-ment
unit and rough position search in ASM AVS.
Local fiducials (67x46) to measure com-
ponent positions in ASM AVS.
Arrows to indicating transport direc-
tion in placement unit or insertion
direction in ASM AVS.
Stop lines:
For application of transparent dual adhesive foil,
For application of adhesive tapes for protection of edges
when spraying spray adhesive.
Calibration structure, to calibrate
the camera distortion.
