CPU Keychain Help: Drilling the hole in the CPU

Fenixgoon

Lifer
So I have an AMD Duron cpu with the pins stripped off, but I can't tell what the rest of the CPU is made of for the purposes of drilling. Apparently if it's ceramic, I need carbide drill bits. So before I blow anything up, I'd like to find out. Ideas, anyone?

if the serial numbers help, i'll edit and put them in🙂
 
Got a dremel tool, with a good assortment of bit's? Just see what works. 🙂

BTW, only a geek would use a cpu as a keychain. I've seen ram used that way too, but I'm sure it's much easier to drill. Then again, I've known chicks, where even a carbide bit is no help, you're just not drillin it, that's the way it is. 😉

well the thing is they're not MINE, they're my dad's.. don't want to go busting his stuff if i can avoid it 😛

Why would he care if you ruined a dead CPU?

Just use high speed steel and go slow, with a drill press.

drill press is a negative. can it be done with a regular power drill?

Sure, but if it's ceramic you need to drill slowly or it will crack. If it was silicon you could just use any ol bit and go to town.

im worried about the drill and the bits, not the CPU 😛

any qualitative ways to tell whether its silicon or ceramic? i guess i'll post the SN now:

19-104-154/125406 and below that is *19023530*
 
If the Duron is ceramic ( looks and feels like tile ) you will have to take it real slow with a hand drill. If its a organic pin grid array you shouldn't have any problem - it should be a fiberglass/epoxy board that can be easily drilled.

I wouldn't worry about the drill+bits, you'll shatter the chip before you break the drill, unless you're doing it horribly wrong🙂

It's ceramic, and a BITCH to drill. I broke 3 dead CPUs before I gave up and used a dead 6800's chip for my keychain.

Edit: pardon my crappy cellphone pic. Seem to have misplaced my digicam.
 
get an artu drill bit.. those things will go thru anything.
marble, river rock, glass, cermamic, cast iron, etc.
i tried breaking one on a 3 inch solid piece of cast iron pushing as hard as i could sideways and i couldnt break the dang thing.

link to artu bits at acehardware.

my store has 1/8" all the way up to 5/8".
 
Yup looks to be ceramic. Never tried drilling one of them but I'd imagine it's a PITA. 🙁

Raduque: How did you get the GPU off the PCB? Or did you just cut off all the PCB around it?

Now THAT is sig material if I've EVEN seen it! 😀


BTW If I was trying it, (Drilling a CPU, NOT a woman) I think I would use a small grinding bit and not a drill bit.

Something like this.

Carbide tip might break the CPU because carbide tip rarely use by pro to drill ceramic tiles. It would be better to spend a couple more bux & get a diamond tip for ceramic, and use lots of water.

That's what I was about to suggest. You need to make sure it stays cool, so flush it with water constantly.
 
those arrow heads are just about worthless. they burn up in seconds.
and that tungsten grinding bit is good for grinding.. bad for making small holes.
get an artu. 🙂

Grinding bits are great for large holes and for cut out (there are some flat or rounded end bits that is quite good for small bore through glass/ceramic), and the arrows bits is great for smaller holes or starter hole. I have use both type of bits to cut holes through porcelain/stoneware/terracotta/granite. The cheaper arrow heads are made from low quality materials while the better ones are diamond tips that will easily chew through 2" thick materials. The trick is to use lots of water.

Many times that I burns through 2-3 bits to cut out an electrical receptacle box because water wasn't available or weren't allow to use, and normally a diamond tip would last at least 14-15 cut out boxes before it break if water was use as coolant.

 
thanks for the replies everyone. i'll check and see what kinds of drill bits my dad has. sadly - no 6800's or P4's lying around for me 🙁 😛

I actually just lifted the whole package off the main PCB using my credit card. With enough force, the ball-grid array connections just break. Then I simply drilled a large enough hole in the corner against the inside edge of the shim.
