Heatbed electrical connection

I've seen a facebook post from Chris Warkocki with a very strange issue: The 2 high-power cables connecting to the heatbed look like are connected on the other side of the PCB, where there are no copper pads, while the copper pads are only touching the screws ....

Question:

Is this the same in all MINIs ? 

 

 

I'm puting here some pictures from Chris' post ( https://www.facebook.com/groups/prusacommunity/permalink/1227584010915662/ )

IIRC MK3S build manual emphasizes to put screws and cables on the correct side and make cable ends touch the pad. This does not look assembled correctly then. Is it dangerous or not?

This thread with x-ray pics show it mounted under as well. https://forum.prusa3d.com/forum/hardware-firmware-and-software-help/pictures-say-more-than-a-thousand-words/ I will check mine tomorrow.

I will not make a summary of the Facebook discussion, but this screenshot seems important 🙂

Thanks for the screenshot. I'm sure it's gonna work fine, but it still feels like the wrong way of doing it...

Might be the first mod to design!

He took existing MINI cover to keep the height and re-designed it to be MK3 style cover.
