I know this is not a pinball EM, but this might come up anyway.
I'm working on a Williams Ringer, and they use a diode in the power supply section to convert to DC.
The diode is mounted to a metal plate (heat sink?), and it looks like they gobbed a bunch of heat sink grease on the bottom where it mounts to the wooden board.
Does this seem normal? Is it necessary? I thought they usually use the grease on the component itself to help transfer heat to the heat sink. I'm not sure what they were trying to do here.
Any input is appreciated.

Actually I have no idea how hot it gets as I haven't had the game running yet.
I was just curious, as I have never seen that used on wood before.
