Naked Phenom part 2

[Cooper]

The HS is actually soldered, not glued.



X2 90nm 2x512KB L2 <--> Phenom

[Kayin]

Did this one live?

[Morais]

thats a big core
Looks like its only soldered at core, no soldering or glueing in the pcb.
The silvered core says everything

[Lightman]

Nice photos Cooper!

Kinda sad it is soldered, but good lapping will give similar results so this is not end of the world.

i dont think soldering is of high quality as shown in KTE's photo

[MonsterMash]

So it's impossible to take it away?
How did you do, cooper, to have a so clean work?

[Cooper]

i used a pci cover bracket from cheap foil made case to cut the rubber
Actually the gap between HS and the CPU package is bigger then that X2.

then i just used the blowtorch on the heatspreader while keeping it face down and it fel off after 30-40 seconds. rest of solder removed with credit card.

you forgot the solder melts and behaves like a liquid when the ihs falls off.. what you see over there is not how it looks like under the cover before..

Did you gained in OC or T?

[Morais]

lol do you guys really think the cpu survived? To fuse the solder the temperature needed is about 300&#176;C.No way it survived.

How did it get soldered on then?

[Morais]

Please, do not mind the temperature I said before...I think the solder used in cpus have a different thermal fusion as its proprieties.I think to unsolder its above 100&#186;C , but to sold it to the cpu the temperature may be lower.

[Apokalipse]

Would it be feasible to sand the IHS all the way down, rather than trying to desolder it?

[Cooper]

CPU was dead in the first place. I ain't crazy enough to conduct such experiments on working one
Actually since the HS is soldered onto I see no point of removing it either lapping it to the bare minimum. Just get a better cooling

[Apokalipse]

Has anybody been successful in getting the IHS off a Phenom, or K8 chip that was soldered on?

I'd be tempted to try it with my 6000+ (ADX), but only if I'm sure it could work.

[Trynity]

yes, that is really easy

i have "decapped" 2 Phenoms right now (9600BE / 9850BE) and booth are workin fine.

what i have done is:

1. Cut the Silicon between CPU/HS with a razorblade (make sure that you not cut to to deep into - i used 6mm from the outer border of the CPU - 5mm if you measure from the border of the HS).

2. Insert 2 Cutterblades between CPU/HS (also not to deep into, but so that there is a little bit tension (don't know the correct English word) between CPU/HS)

3. Put this onto 2 or more stands - so that the CPU is free and will fall down when the tinsolder melts

4. Transform yourself into a Firedevil and heat the HS up, i personaly use a Gas soldering iron, other's prefer a handleiron ("B&#252;geleisen").
(there are different Ways to do this)

sorry for the bad (english) description .....

[Nedjo]

it's shame that you didn't do a photo guide Trinity

[LIKMARK]

Including a heartbeat reading when you did it.

[Trynity]

i think the heartbeat was normal *g*

Unfortunaly my Digicam was not here as i have done this, but if i can get my hands on another Phenom i will make movie from the process

KTE
CPU was dead before you cutoff heatspreader? Right bottom corner look like thermal damaged without thermal interface.. You can shot this place with more magnification?

KTE left the forum a while ago.

Ok Two options Ive Done,, Option One is to unsolder the 6000+.......
Oh 50&#37; chance you can kill it too






Option Two,, Sand Lap for a Few Hours to get the IHS to 1mm thick.....

Also 50% chance you can bust pins

I removed the IHS's to show how thick the Stocker is Compared to Sanding and then Lapping Mirror mooth...









When i sanded the IHS I used some Old CPU tray's and an old 940socket tray (stole from dead Board)
Cut one tray to fit inside another ,,Insert the (cpu foam) under the 940ZIF tray...

940Zif,,Foam,,Small tray,, use blue painters tape to to hold Cpu and trays together...Now set the taped Cpu in the bigger tray and tape once more..

Now your ready for the 100/120grit wet dry...then 400/600 and onto 1000/1200 and Finaly 2000....










Note: Unsoldering resulted in about the the Same Temps(+-1-2c )Vs By Sanding/Lapping the IHS....Sanding IHS you leave a very thin edge that supports the W/B with out as much Risk of Crushing Core....Ive Shatered Cores Before and Thus when i want to get down and Crazy , I now just san it paper thin,No more risk of Cooking Core(unsoldering) or shattering under Preshure
