A common problem with the Mionix Naos 7000 is that the scroll wheel click button breaks. As it feels kind of wasteful to throw an otherwise fully functioning mouse just becase one switch breaks I decided to try to fix it. So I ordered a pack of EVQP0E07K Micro Switch and began breaking into the mouse.

Removing feets The feets are removed with a hair dryer and a knife or putty shovel. Underleath are the screws.

Daughter board The daughter board and LED-board needs to be removed to reach the switch. One is mounted with two screws and the other just pulls off.

The scroll wheel The scroll wheel’s axle rests at the switch. It was a bit tricky to remove the wheel, but its possible to wiggle it out.

The solder before desoldering the switch The back side of the main PCB before desoldering the switch. Clean, nice.

The solder before desoldering the switch The back side of the main PCB after the switch was replaced. Utter horrible solder and even worse desolder.

Anyway! I got it working again.
