3.7.5 Definition of PCB warpage
3.7.5.1 PCB warpage on the conveyor
PCB warpage across the direction of travel max. 1 % of the PCB diagonal, but not exceeding 2
mm.
3
PCB warpage in the direction of transport + PCB thickness < 5.5 mm. Bending up of board edge
max. 2.5 mm.

3.7.5.2 PCB warpage during placement
3
3
Changes in the surface position are automatically applied by the functions for learning the height.
3
3
PCB warpage up, max. 2.5 mm
PCB warpage down, max. 2.5 mm
PCB support
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.
