-Cleaning alcohol
-Razor Blade
-PTM7950
-Variation of Sandpaper (400-2000grit)
-Even Surface (white brick thing for me)
-Coppershim (20x20x0,8mm)
I pried off the Original Shim with the Razorblade.
Sanded and lapped the Vaporchamber to get rid of the residual Solder.
Deburred and lapped the new little Copper Shim.
(Clean everything in between with the ISO)
I made a paper stencil of the Die to easy cut the PTM for the Die Side. Put the PTM on the Die.
Layered the Coppershim on the PTM and put a precut PTM Sheet on the shim (the whole size of the Shim)
And screwed the Heatsink on Top.
Done, heatcycle is like the first 5-10 full Heat and Roomtemp Cooling Cycles.
== Performance
I didnt even remove the Board or anything it took like 20min for me.
