To lap your cpu you need a few basic items as shown in the pictures below. A pane of glass, good sticky tape, sandpaper (800, 1000, 1500 and 2000 grit), cpu,1/2 a business card and a few sheets of toilet paper.
I start preping the cpu by taping around the heatspreader
.
I then take the toilet paper and business card and cut them to the approximate size of the cpu.
I place the toilet paper on the back side of the cpu and then the piece of business card goes on top.
Then I fold the tape over to hold everything in place.
We'll start lapping the cpu with 800 grit paper. Tape a sheet of 800 grit to the pane of glass and lay the cpu, heatspreader side down on the paper and were ready to begin.
These YouTube videos will show you the basics.
I like to make 10 passes and then rotate the cpu a 1/4 of a turn. Here are a few pictures showing the progression.
1st Pass at 800 grit
Still at 800 grit.
This is the result of my Final Pass with 800 grit, time to switch to 1000 grit.
Using 1000 grit I continue rotating the cpu 1/4 of a turn for every 10 passes. When the entire heatspreader is flat and smooth were ready to switch to 1500 grit. These pictures didn't turn out as well as I would of liked. You can't see it but the heatspreader is now showing a blurry reflection.
After moving to 1500 grit and following the same 1/4 turn after 10 passes I continue until the heatpsreader is producing a sharp, but slightly scratchy looking reflection.
Moving to 2000 grit paper I follow the same procedure until the heatspreader produces a super shiney reflection.
Remove all the tape, using compressed air clean the cpu throughly to remove any lint or metal flakes and your ready to go
