Changes in the surface position are automatically applied by the functions for learning the height.

PCB warpage up, max. 2 mm
PCB warpage down, max. 2 mm
0.5 mm
To avoid impairing the placement quality and speed, we recommend using a PCB support e.g. Smart Pin
Support so that the PCB warpage downwards does not exceed 0.5 mm.

3.7 Vision system
3.7.1 Structure
A component camera is integrated at each Collect&Place head (SIPLACE CP14/12/6). The com-
ponent camera, stationary, P&P type 33 GigE, type 36 GigE and type 25 GigE for the SIPLACE
TH/SIPLACE PP head is 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.
