sdc2130 mounting considerations

Hi, I recently purchased several SDC2130 boards and was wondering if their heatsink plates are electrically isolated from the board\'s electronics. I plan to mount them to the chasis of my robot if that is the case. I searched the datasheet, but couldn\'t find that information...

The plate should be isolated from the rest of the circuit and should not cause problems while connected to the robot. The only thing to take note of is that on the bottom side of the plate, there are holes where some of the through hole components go through. If those short to the robot, then that will cause problems.
