Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper EPAD Exposed Pad. Connect the exposed pad to the potential of the VSS pin, or, alternatively, leave it electrically unconnected. It is recommended that the pad be thermally connected to a copper plane 17
