The Metal Cover Plate (I am not sure what's called) on my Yun has come loose.
I was wondering if someone could clarify what it's for, and the risks of leaving it as is. For instance is it a heat shield, heat sink, antenna, radio shield?
Around the failed solder points attaching the Cover Plate to the board, there are what look like deformities resulting from overheating that weren't their before ...
I have recently started powering this Yun with external 5V switching power-supply (e.g. into Vin and +5V), and concerned there may be something causal here ...

Incidentally I decided to jump both Vin and +5V because of these posts
ShapeShifter:
My assumption is that the metal cover is a shield to help cut down on RF (radio frequency) interference.
@ShapeShifter, Yes, this is so, but also cutting down on the RF Interference makes it so an antenna does not have to be some distance from the generator and receiver. In other words, it does not interfere with itself. But that is a more minor case, generally it reduces RF radiation - as expected.
The article below covers the general case, not the specific I mentioned.

So, in other words, it reduces RF interference, AND it reduces RF interference.
It also cuts down on potential incoming interference interfering with chips and traces under the can. That interference can come from external sources or from the WiFi antenna. So in reality, it reduces RF interference, and it reduces RF interference, and it reduces RF interference, and it also reduces RF interference. 8)
