Hey Guys
I had a dead motherboard laying around which I was about to throw away.
So I thought it would be interesting to take a look inside the CPU itself.
I heated the puppy up with a hot-air gun, and lifted the CPU of the MB. And carefully broke of the fanout board from the core itself while applying heat with a blowtorch.
I ground the CPU on 1800c sandpaper with a glass plate underneath for a short time, to get a nice surface as of pic 1.
I discovered that the copper interconnect layers, and dye itself was so ridiculously thin that it was impossible to control the grinding this way (pic 2 and 3).
So I took a tiny peace of sandpaper, and bend it to get a sharp point which I could use to grind down more where it needed to. I finally, at the very last layer, managed to get (almost) the whole dye visible.
It looks very fascinating if you haven't seen the guts of a CPU before.
(The pictures are not the best, but bear with me, it's not easy to focus on such a thing, while getting the right angle of both (a very bright!) light, and camera at the same time
WHILE KEEPING THE CORRECT TONGUE ANGLE !)
Hope someone find this interesting, at least I had fun with it
