Yeah, can I ask Vince what chassis are the Xboxs you have ? Xennon or falcon etc ??

I would buy a station today but I just dont have the space at my moms house to store things with all the Tv's I have.

No idea too be honest i havnt even turned them on or opened them yet as only got them the otherday i will let you know when i have them open etc and what faults they have i will start a new thread as dont want to mess this one up.

I could do with investing in a bga station too that kit does look good imo as have 3 xbox 360s here to look at asap.

Peanuts now , have a look on e bay , you can buy Chinese station for less than £300 , this kit cost me over £4,700 when I bought it 15 years ago.

Hmm...

Been researching this re-balling lark and it seems thats not the main issue of these things failing...
It would appear the fault isnt that of the soldering of the chip substrate/balls/mainboard, but the silicon-chip itself to its substrate...
--Which stands to reason, as its the chip that gets hot/expansion/contraction cycles etc.....

Heating the chip--as in re-ball/flow shifts all that silicon to substrate around a fair bit in comparison to normal and temporaraly fixes the fault.
Only proper cure is to replace the chip complete, and add better cooling....

It appears that reflow/reball is therefore just a temporary fix, therefore not much point for reliable repair....
