3.7.7.2 PCB warpage during placement
A warpage of 2 mm can lead to problems focussing on local fiducials and ink spots in the middle
of the PCB. The digital camera's focus is 2 mm. When all the tolerances are taken into account,
this value is reduced to 1.5 mm. Also note that the component height is reduced by the warpage.

3.8 Vision system
3.8.1 Structure
A component camera is integrated into each Collect&Place head (see Fig. 3.5 - 2 page 108 and
Fig. 3.5 - 4
page 112). The stationary P&P component vision camera (type 33) 55 x 45 digital for
the TwinHead is permanently fixed to the machine frame.
The component vision module is used to determine:
– the precise position of the components at the nozzle and
– the geometry of the package form.
The PCB vision module uses fiducials on the PCBs to determine:
– the position of the PCB,
– its rotation angle
– and the PCB skew.
The PCB cameras are fixed to the bottom of the gantries. They use fiducials on the feeder mod-
ules to determine the exact pick-up position of components, which is particularly important for
small components.
WARNING
RISK OF HEAD CRASH 3
When the placement head is changed from the TwinHead to the Collect&Place head, the Twin-
Head's stationary component vision camera, P&P (type 33) 55 x 45, and stationary P&P compo-
nent vision camera (type 25) 16 x 16 digital must be removed, otherwise the Collect&Place head
will collide with the camera housings.
