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

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.
