PCB Warpage
PCB warpage during placement
PCB warpage downwards, max. 0.5 mm
Use 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 also
reduces the component height.
