Observation of substrate deformation using a 3D shape measuring machine (VR-6200)

This is a measuring device that can non-contact measure surface shapes such as concavities, undulations, and surface roughness. We will introduce "heating deformation observation" using a 3D shape measuring machine. First, we acquire a 3D texture image at room temperature, and then we acquire a 3D texture image in the heated state. By overlaying the texture images before and after heating and checking the differential texture image and cross-sectional profile, it can be seen that the substrate in the heated state has higher ends and a lower center compared to the room temperature state.

I would like to introduce "Observation of Substrate Deformation Using a 3D Shape Measuring Machine." By applying pressure to the PCB substrate, referencing bending tests of plastics and PCB substrates, the change in state is measured using a 3D shape measuring machine (VR-6200). Since the measurement results can be confirmed with a color palette and line profile, it is possible to visually verify the shape and amount of deformation caused by the applied pressure.
