PCB Warpage
PCB warpage during placement
PCB warpage downwards max. 0.5 mm
Use the magnetic pin supports, to achieve
this value.
When there is warpage under 2 mm, the
inkspots in the center of the board are also
within the focus of the digital camera. When
all the tolerances are taken into account,
this value is reduced to 1.5 mm.
You should also note that the warpage
reduces the component height.
