- Soldering equipment

Tools recommended: 
- Mechanical desoldering pump and desoldering mesh
- tweezers
- Head light

 All noises are either pure Matrix-1000, or pure Untergeek. 



When changing the chip, as shown in the video, be extremely careful - insert the blade between socket and chip, not underneath between socket and PCB, or you will damage traces.
