Measuring component height after reflow

I have an SMT component that has a height of 8 mm with a stencil thickness of 5mm. We are using lead free solder paste, the pad size is 11"x.054".

Is there a method for determining the overall height of the component on the board after reflow?

I would suggest using a VPI-1000 from Easybraid. Once the assembly is reflowed you can simply measure the height.
