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 For best soldering practices, the minimum trace length should extend to include the pin solder mask. This way during reflow, the solder has the same copper area as connected 9
