Nvidia GPU chip problem

You should bear this in mind using IR while reworking.



Would prefer it to have USB to instead of RS232.
But with an USB2RS232 converter you an use it for reading out the graph plot of the profile while using it.
Which is the most important for me .
Programming I prefer manually to be sure everything is 100% correct.

About hot air, it can do faster profiles than IR.
When used carefully, not as easy popcorning as IR.
Not saying you don't get popcorning with it,but think you can go higher temps.

i aggree, allot of people that have gone from ir to hotair say thy have noticed the difference & hotair is better, but whatever works for different people is good.

Like the WHYSIWYG of my Achi or most IR.
You work with "real" temparature.
I mean, like on my Achi, the TC controls the heater.
Controlling the temps on/against pcb/bga.
If you want a BGA to to to 225, you set it to 225 and adjust timings, dwell etc...
(Jovy 7500 does the same, but much harder to control).

On the 3 zone hot air machines the TC only plots a graph.
The hot air temps are controlled by "internal" TCs.
This means you have to set them to other (higher) temps than the actual temps you want on the chips.
Once you understand this and know how much the differences are, probably not a real problem and easy enhough to.

Like reballer says, whatever works for you is fine.
In the end, it is more the user/operator that has to understand what he/the machine is/can do.
Many here can do magics with the Jovy.
It's was just so hard to learn at the beginning.
No info, support, resultingin popcorn, delamination etc...
Did learn a lot from it though...

So when is this RE-8500 going to start shipping out? I may just sell the Bird.

Did you regret buying the Bird?
After using it several months, how does it compare to the jovy re-7500?
(I know I asked this before allready but then you only had it for a short time)
Did you change the TC on the Bird?
If I am correct, it comes though the IR heater, sitting on top of the BGA?
You should change it like Achi stile.
A TC wire you can place anywhere.
Works much better.
Also, if you put an Elstein SHTS/4 heater in it you'll get a whole new machine.
The power of jovy with much, much better control.

No i have not used the Honton. But it looks good.

I use the RE-7500 for two years now and ordered a new RE-8500 that i receive in about 10 days.

You are right that the PS3 is a hard thing to do with the RE-7500. But with if you take your time for pre-heating and also let the upper heater pre-heat in relow mode (i don't never ever use profiles) I can be done. I do 5 to 8 ps3 a week.

Popcoring is always caused by moist (bake the chips) or more then 2 deg/sec ramp up. Not by the Jovy.

I will let you guys know how the RE-8500 performs.

@deusjevoo are you from Holland?

Hello guys, I was just wondering if you can use GF-GO7600-H-N-B​1 chip on mainboar where previously was GF-GO7200-B-N-A2.
thanks for answer

-21s

what is the problem if a dv9000 boots with black screen (no beeps). should i replace northbridge or gpu? the board are from china and it works only a few days. poor quality

another question: can i replace a mcp67mv with a mcp67md? notebook has a external graphic card (acer aspire 7520g).

thanks a lot. glad to have you all

Think a better test is FURMARK.
FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

If you combine that with Prime95 or IntelBurnTest (yes, run them together) you can stress out both cpu and gpu to the max.

Does anyone have problems with loose components on bottom of a pcb?

When the thermocouple is moving (through the heat) the the probe sometimes shift components on the bottom side.

On a multilayer pcb it's not possible I think to have a big temperature difference on bottom and top on the BGA place.

Any experiences?

GF-GO7600-H-N-B​1: no
GF-GO7200-H-N-B​1: yes
GF-GO7200-B-N-A2: yes
GF-GO7200-B-N-A1: yes
GF-GO7200-B-N-B2: yes

7300 and 7400 chips works too. But i dont know where i can get this chips really new (09+). Reballing does not solve the problem.

Not interchangeable.

[Dan Collins]

How about interchangability of
216-0674022, 216-0674024, and 216-0674026 AMD/ATI Radeon.
Anyone done this with success?

[Dan Collins]

For all of you that have no success replacing the GPU, assuming it is a good chip and reflow, I have found that the extreme heat caused by the CPU sometimes also damages the solder connections on the CPU socket as well. I have had little success reflowing a socket, but good success replacing the socket. I think the connections may be also damaged inside the socket. Most of the heat causing these problems actually comes from the CPU, so it makes sense it is also affected. This is mostly with AMD processors.
A good easy test of a bad CPU or socket is try to see if either memory socket works. If only one works, then you have a bad CPU or socket.
The other thing, is always try another known good CPU. They burn up too. The AMD CPU's tend to get dark when heat stressed. Discard any that look darker than normal.

22<->26 tested both variants working
