Fix XBOX360 ring of death with RE-7500

[badnes5]

I've been using re-7500 for a while now - it's pretty fair to say that it's not the easiest or the best to use ... but - it is pretty good value for money when you learn to overcome most of it's difficulties.
If you're trying to reflow 360's (as we were) the first thing you'll do is damaged boards beyond repair...you need 5-6 to practise on.The main things we had to sus out are the following;

1.buy one of these
http://cgi.ebay.com/ws/eBayISAPI.dll...:X:AAQ:US:1123
we made one up from 3mm aluminium plate - nothing now moves under heat - we also put an additional support (adjustable) right in the underneath centre of GPU to discourage it from bending down.

2.Remove a GPU from an old scrap board and test what happens with your profile - the temperature in the centre of the GPU varies greatly than the sides - you may measure 160C but the centre of GPU will be possibly 180C - try to reflow a board without GPU - test at what temp the solder melts ... the jovy probe may only read 180C ....it's meant to be 205c for lead free - right !?
We also use another calibrated hand held temp gauge to test underneath of GPU ....too much heat and the board will unneccessarily distort ... this may leave the motherboard un-useable....
try fluxing the area with no gpu on it and watch at what temp the balls reform - it'll be lower than you expect.

3.Use a rework solder flux - we use a spray to ensure the inner balls of GPU are covered .

4.You will always come across boards that will not reflow/repair/reball - reason is that when the GPU heats and distorts the board - the tracks that the solder balls are attached to can break off the board - inspecting with a scope will show that it's usually the corner tracks that are affected ... you will see a 'dead pixel ' in the row of bga pads !

we get a 90% success rate with 360's - with around 10% scrap boards - reliability is on the way up with maybe around 20% back for reflow - 50% of them don't fix again ... we turn around 8-10 a day .... never expect a full 100% as you won't get it ! ..... no matter what equipment you use.

has anyone used one of these ?

8-10 a day includes ps3 YLOD - different clamp but same profile / process

May I ask how we're providing top heat to the gpu when its covered in kapton?

[Dan Collins]

I cover only the exposed chip with kapton, not the board the chip is on. helps reduce the heat to the chip a bit, but maybe the greatest threat to the GPU is the heat delaminating the small board itself, which then the only recourse is to be very careful of amount of heat applied. I find you usually have one good shot at a BGA reflow. Subsequent reflows have more trouble. I have more success with a new chip, but then even one must be careful not to break pads from the motherboard while removing the old chip. Also, if you improve the heat dissipation so the GPU will not overheat as much in the first place, return calls will reduce.

On the zytronics. I have the board holder and the lower heater unit only. Which is great to do rework with hot air. brings board temp to 150c. Great for small smd componets.

But I find that the most important tool in my arsenal is my microscope inspection station. It really helps to see what is really happening. Trust me on this one. If you don't have one, get one.

what model do you have ? What price can we buy and where ?
many thanks

Hi,

I am setting up a approved repair centre. It is aproved by
microsoft,sony,dell and hp all the equipment and methodes we use are
aproved by these. the equipment is the same as microsoft use in there
repair centre in germany and the rest of the world same goes for
sony.the turn around will be 5-7 working days. the price you can ask
for a repair is between 75 and 100 we recomend 85. al our work comes
with 1 year warranty

any more quistions feel free to contact me

my e-mail is [email protected]

my tel 0161xxxxxxxxxxx
mob 0752xxxxxxxxx[/COLOR]


think that he's talking shxt - quizzed him about the stuff he's using and he can't tell me.




hi

i think you got your info wrong the plant in germany (Bosch) are using the same equipment en methodes as us. the official repair centre in germany (Bosch) dont replace the motherboard they reflow or reball depends on wat the tests come out with and after the repair there some more tests to make sure everthing is up to standards the repiar centre in german is in contract with microsoft and if the fail to repiar they send a refurbed xbox back the dont replace the motherboard thats a fact

the equipment im using is per reflow/rework station 22000 pounds and is used by microsoft , sony, dell and hp

sony playstation 3 are not being reflowed but reballed as there are issues with the lead free solder


don't think bosch have anything to do with repairing xbox360's either -

Hi to everyone in this thread who have been experimenting with the jovy systems re 7500. I must really say thank you to you all as i am going to be getting one of these soon as well. The time and effort you have put into the machine and the generousity you all have for sharing this info with the community is very much appreciated. As i work with the machine myself i will post my success and failure rates and try to contribute as much as i can myself. Thanks again

• Things should be used

JV-F030 (Flux of 30cc)
JV-K030 (protective Kapton tape)

JV-LSU ( 2 supporters )

• Things to do before starting re-flow

Cover the GPU with protective tape after you clean the thermal paste .
The thermocouple prop bended 6 mm , put in upper side of the GPU on PCB not over the GPU and touch with all the 6 mm area the PCB surface.
Apply the flux on 3 sides of the GPU.
Use 2 of the supporters under the GPU
Never use the lower heater in Re-flow mode or Fast reflow Mode in all your re-flowing
Make the profile end on 195

Don't use the fan for cooling when PCB over 120 (never)

• Manual & Profile control

Preheat the PCB manually to 60 degree , use preheat mode ( do not be hurry )
Use profile you got from JOVY (do not forget to make the profile ends on 195 this is my way)
When you starts the profile make the upper heater to level 3 or a little bit lower.
At 160 make the upper heater to 4
Heaters setting is ok in the original profile
Most important do not turn the upper heater to park mode , after finish the profile keep the heater in same position until the PCB reaches 210 then you will see clearly the temperature will go down , turn the upper heater to park mode when PCB is 180 , start the fan on 120 or lower .

Most than important Do not remove the PCB from holder before it come to 50 and become cold .

Hope this end the arguments here . Simply you have to spend time with your new machine . before all people use hot air and hot gun or light fast IR . here you use dark IR . this is like people used hot air in 1997 and burn huge number of PCB . Unless you understand your machine you will not get the benefit.

Regards to all

Hi I need a profile to reballing GPU Xbox lead free

[procesoare]

Hi
I buy a rework jovy re7500 and not work good,need a xbox profile lead free,to reballing,can I found here?I try reflow but not work ,must be reballing.and some instructions.
Thanks Daniel ROMANIA.

Hey guys i have had this machine for about 3 days now and just wanted to let you all know my experience with it.

First all in all i am very pleased with this machine. It has worked very well for me and just today i have fixed 8 boxes and 2 ps3s. yesterday 3 xboxs. the only problem i had with it is that it came with absolutely no instructions on how to really use it so here is my advice and how i got it to work for me.

When i first got it, of course because it did not come with very good instructions and because i had no idea how to really use it, i did what any one else would do and went online searching for other peoples profiles so i can use them. Let me tell you that this is a bad idea and you should not do this. when you first start running the profile you are going to get discouraged because your whiteline does not(and will never) follow that blue line that has a perfect arch. No instead you are going to see your white line rise a little bit and not even close to as fast as the pic on the graph. i watched and watched and got more discouraged as i did and began to think that something was wrong with my machine. So of course after the first profile i got i searched for more and came across two more and of course again they did not work for me. So what i suggest is to not do that and to do as follows.

At this point following others profiles and being discouraged because my line did not follow the graph, i had burned up 3 scrap xbox 360s(lucky they were scrap boards). What i finally did was toy with my machine, i took one of the scraps and put it on the machine. I then watched what degree my TC told me when i was able to move the chip. It said 180. this was strange to me because we all kno lead free should reflow at around 215-220 and yet i was able to move this chip and see the balls reforming at 180. this was the reason i was burning my boards up, i was using other profiles that took me to 215 225 and even 235. According to how my TC was reading we can all understand that i was killing these boards by going at the rate of the other profiles. What i was able to gain from this is that all of our TCs read different degrees on all our machines. that is the problem with this machine and why it is so hard to use. So in order to make sure that this was the reading i was going to get when reflowing i reflowed this board about 4 or 5 times to make sure the reading was consistent and it was, so my machine reflows when it is about 180 which is really the equivalent to 215-220.

My advice to anyone getting this machine is to honestly forget about the profiles until you know how your machine works, because if you just start using a profile from someone else you may get really discouraged and no longer want to deal with the machine. Get a scrap board to work with and pay attention to what degree your TC gives you when you are able to start moving the chips, this will tell you when your machine is really at around 215-220. The problem is that the TC does not pick up the reading as well as we would like it to but this can be worked around by just working with your machine. So just make sure your readings are consistent so you can start your real work. Honestly i only reflow manually i dont even use the profiles because i really dont like it all too much but that is just me, i also fine reflowing it manually forces you to pay more attention to what you are doing.

Hopefully this can help everyone out who is just starting with this machine as i have said before i am quite happy with the machine now that i have figured mine out and i hope this will help some of you figure yours out. Think of the machine as dyslexic as compared to other hot air machines as normal readers. Just because it sees things differently does not mean it is not as good as a hot air machine it means you just have to work a little harder and differently to get it to work, in the same manner as a dyslexic kid is not dummer than a kid that reads normally they just have to learn a different way. thats how i see this machine you just have to work a different way to get used to your machine.

Well hope i can be of help. Srry if my message is too long and not too understandable its a little late here and i am quite tired. so if you have any questions go ahead and ask i will be happy to help.Thanks
