How To Remove Ram With Heat Gun? Or Whatever, Read for humor and possibly u can help! Options

[sirotz]

Im still freakin stuck... really. I can't get those damn chips off. And nothing around here has everything localized for research. (When I complete this a tut will deff be made to save others my headache) So Ill start from the first thing I tried.

1. Heat gun. I have no Idea what the heat settings are with this damn thing. it says from 220f to 1100f. But the settings are numbered 1-9. So I chose about 4 and a half. I read "it only takes 15 seconds" well 15 min later I was still holding the gun like a freakin tool. "Heat from the back and the chip will just drop". When? 2005? I don't want to up the heat to much because I'm afraid of frying the mem. Although I just might have done it the next way.

2. Baking. Yep Im a dumbass I know. I saw this post and had high hopes. Someone said "the shock level is about 500f give or take. Set it around 350f". Perfect how can I screw this up. Had it in for 10 min and read a little bit closer "Only use the grill" Well freakin great I used bake cause I don't have a dang grill on my oven. It's Bake or broil.. that's it. So I took the motherboard out and everything is still sitting there mocking me. But now I worry...did i fry my mem? I don't think so but hmmm I just might have.

3. Wire trick thingy. This seems simple enough. Wait a tick 30 gauge wire.....ahhhhhh!!!!! nobody sells that around me. Well looks like I will have to use the other idea. "Try and old ribbon cable!" So I grabbed an old harddrive cable snipped it and AHHHHH It's mocking me Damn you memory!!! Stranded freakin cable, thats what was inside. Completely useless.

So now comes the part where i beg on bended knees what to do next? Where might I have gone wrong? What can I change or do differently? How in the name of everything that's holy in this world can I get this freakin memory off of this xbox?

The world is a cruel fucking place for people like us. Sometimes it just seems like there isn't a goddamn place around that sells anything remotely like what I need.

with the heat gun try upping the heat ever so slightly until the solder melts, the solder will melt before the chip dies, solder melts at a lower temp than the chips die at.

with the wire method try using the ribbon cable and twisting the strands to keep em together, or you may be able to use 1 strand if its not rediculesly thin...

i dont know about the baking method, just try these first then come and ask again

[sirotz]

Alrighty now we're getting somewhere. But with tthe heat gun which way is is best to heat the board. Is it better to heat the chip from the back and wait for it to fall or is it best to heat it dead on and try and lift it off?

[Andy Holloway]

well ive never actually done anything like this before but there is a chip on either side of the board so i recon just lift the board up and point the heat gun up at it from under it (yes straight at the chip, actually how fine of a point can you heat with one of them? you may be able to heat just the pins around the outside...i doubt it lol) and see if it falls off or anything
if you have another person to help you may be able to use a knofe or something to slip under (CAREFULLY and only when all the solder is liquid, you dont wanna bend the pins) it if it doesnt wanna fall straight off (solder is sticky when liquid)

[-Gadget-]

what is your end goal in this ??
to remove from a 'non-working' xbox to put on a working mobo ??

if so u need to get all chips of in good working order along with all the pins straight so its easier to soler um on ..

ok

the two methods i would suggest

1. the ugly method..
get ya heat gun
wack it to nearlt thhe the max (one under its max)
now ... looking at the chip u want off....
hold the board upside down
now get ya heat gun and hold it about 2cm(1inch) away from the solder pins
swutch on and slowly in a circular pattern go around the chip
(this is to stop hot spots and so on)
no, as we all know the solder melting point is LOWER than the chip max temp
sooooo in thoery as long as u keep the heat even around the chip, once the solder gets hot enough it will 'fall off' hence why u are holdering it upside down
keep going around and if need be, turn gun up ...

this can be dificult working up side down and so on...
and getting all the points to melt at once so that it falls owf !! ... so maybe some kinda tool to gently tweak the side to see how melty the solder is ..



2 the better method..
get some desolder wick and a pretty high wat solder iron (like 30w ish)
now lay the solder wick along the oe row of pins and apply heat
the wick will remove all solder
do this on all rows and then getle lift the chip.. seeing were there is exxcess solder left
and re-doing to wick treatment ..
u will need thin wick for this to get enough heat in..
for example 1.5mm
this method i know works as ive dont this on other types of chips (two sided ones .. but not done it on 4 sided chips thou ..

hehe soldering irons here are 60w standard, beer to 240v!

By the time those RAM chips come off, they will be so toasty, I wouldn't chance putting them in a good motherboard.

Heat gun method will work, but be careful. Heat from the top of the board and lift gently when solder liquifies.

For someone who wants undamaged RAM chip removal, I recommend professional removal, or buy Chip-Quik.

Thanks for a more indepth heatgun tut. I will give this a try. I have a nice solder wick but only a 15watt soldering iron. Oh well here goes nothing. I will post my results.

240V is the mad note!

got the mem off with little effort. Installed it last nnight but my box fragged. I had a feeling it would do that. I just need to go over everything and triple check. I will pos tthe results. Oh by the way if I did fry the mem how would I know? Would it frag or give me a mem error when properly installed?

did you use the heat gun in the end? hopefully i will be doing this soon too

thats something im worried about, there is so much to check over,
something i was wondering waws would it be possible to install the chips one at a time? like put one in, see if it works, then if it does you can go on with the next one, if it doesnt you only have 1/4 as much to check for shorts and that (yeh i know you should be 99.9% sure you have no shorts before you turn the box on but still)
and then if say your first worked and you did the second and couldnt find any shorts, you could desolder that one and try an other to see if its the chip thats bad (a lot of mucking around but its easier than working out which is bad if you have 4 installed and have no idea if any work)

Everyone says the chips can withstand whatever temps, but I would be careful and only heat the pins and not use any of the other methods because the datasheet says the max die temp is 150C or 302F, it might not kill the chips to go above this temp, but then again the datasheet for them says it will.

[sirotz]

I ended up using a heatgun. Jacked up the heat then blasted the mem for about 25 seconds picked up a corner and dropped it nocking the chip out with virtually no solder on it.
