General Inactivity

Post by Jim » Wed Jun 20, 2007 1:55 pm

I got injured in a car accident about three weeks ago, :x so I haven't been doing much lately. Hopefully eventually will be able to get back to work on my dogs, but for the time being not much happening..

Ouch!
I hope you'll be ok soon Jim!
Take care.

My K6 is feeling alone also. I've got too work to do right now in my real life.I'm still waiting the time to test 2x256Mbyte of ram double sided on the K6-2+ @ 5.5 multiplier in order to rise memory scores and blast 4000 points at 3dmark2001.
My M577 is also waiting and I thank you again for the cables ;)

Oh and there's a new.
I found a K6-III+ ACZ, but it's attached at the PCB of a notebook that maybe was the motherboard of a notebook.
I'm looking for a way to resolve the CPU form the PCB...

Thanks Mamba, - the thought is appreciated. Should be ok in a few more weeks.

hope u are allright, jim. best wishes from germany ...

an idea concerning to get the cpu off the pcb. there are some hot air blowers, which we use here in germany to heat up the coal for grill parties. i think two of them would be sufficient to reach 505K (232C), the melting point of tinn and unsolder the cpu. after doing so u just have to get rid of the left tinn on the 321 pins ...

Thanks Kalabok, wishes appreciated. @ Mamaba : I am not sure about how best to go about salvaging that ACZ. Would seem to me that the safest way to go about it would be to get it done professionally; problem w/ that is it would probably cost more than the chip is worth. As for doing it yourself, Kalaboks idea is as good as any; but I don't know how well it will turn out. Don't know how much heat they can take, or for how long they can take it.

Do know that I have a spare K6-3+ 450ACZ kicking around that has never been used; - (or even tested, - it is still sealed in its original package.) - if you are interested.

Sorry to hear about your accident Jim. Get well soon.

I had to re-read your initial post because I didn't get the "dog" thing...then I figured out you meant the "puppies". :P

@mamba -

I'm not sure where you got your temperatures...but the standard Sn63/Pb37 solder melts at 375 degrees F (190 degrees C).

At work, we would put the board in an oven first to pre-heat everything up to temperature...then do the final removal by hand.

In any case, you'll have to watch the heat gun temperature...and you'll have to make sure that you do it evenly so that all of the pins are released at the same time.

As for the residue...same thing. Heat the pins, then use a soft brush to wipe the remaining solder blobs off as best you can. Having a lightly tinned surface should be OK. Don't forget to clean off the leftover flux as well.

Thanks KachiWachi, thoughts appreciated.

@ Mamba : Follow KachiWachi's instructions. He is a professional at this sort of thing. What I would do is preheat an oven to the specified temperature, (preferably with a high temperature oven thermometer in there to check the temp.) When you have fiddled the temp control on the oven to the point where the thermometer says it is at the right temp, THEN put the pc board in to heat it. Hopefully KachiWachi will be kind enough to give you some idea re how long you should leave it in there before trying to remove the chip.

:shock: Get well soon Jim. I'm very sorry to learn about your accident.

I've been abit too busy myself lately to tinker with the machines. With the nice weather my wife has me doing home improvement projects and my 3 year old boy always keeps me stepping.

thx kachiwachi, now i know its not pure Sn used for soldering electronic parts ... the melting temperature is indeed 183 C. to tell the truth, i wouldnt heat the whole cpu, as there is a probability to unsolder the small units placed on the top of the ceramic base (what are they, actually?)
the max Tstorage given by amd is 150C. no idea, if the cpu can stand that oven treatment.

@ Taz : thanks, it does seem to be getting better, (if slowly). @ Kalabok : good point. Perhaps KachiWachi could be prevailed upon to make an exception here and give detailed instructions as to how to go about it. One way to do it would be to rig up some sort of clamp holding the cpu chip w/ the board suspended by the clamp holding the chip. Applying heat to the back of the board that way would cause it to fall off. I don't know. Never tried anything remotely like this. Another thing Mamba could maybe do is mail the whole thing to KachiWachi if he is willing to do it for him.

I think that Kakiwachi treatment would make the puppy... An hotdog...
(IMHO)
Anyway I appreciate your suggestions.
Jim I'll let you know if I need you "spare" K6-III+, now I'll try all I can with this one, thanx.

I don't know how long to keep it in there...the "girls" took care of all that. :wink:

Storage Temperature is different than Soldering Temperature. I'd check out the AMD Technical Documents on this (Unfortunately, I don't have the numbers for them).

Thanks.

I managed to resolve the two external lines of pins, pin by pin. But I cant' go through this way.
It's really challenging, if you won't fry the cpu also, obviously.

Meanwhile I get an MVP3G5... :P
