Vacuum tooling
Workpiece carrier
The front and back edge of the workpiece carrier may not be curved upwards. There is no guarantee that
the curvature will be pulled flat by the vacuum tooling.
Warpage across the direction of transport max. 1 % of diagonal but not more than 0.1 mm. The warpage
is then pulled flat by the vacuum tooling.
The side edges may not be curved downwards.
The side edges may not be curved upwards.

Fiducial environment Clearance around reference fiducial not necessary if there is no
similar fiducial structure in the search area.
*)a To ensure good production quality of boards, a minimum X/Y size of 0.075 is possible
for circle fiducials under the following conditions:
Absolutely no other objects are in the square search area and fiducial size + 0.2 mm visi-
ble.
Example: Circle fiducial with X/Y size of 0.075 mm requires a search area without visible
objects of ≥ 0.075 + 0.2 mm = 0.275 mm.
