Sapphire Radeon HD 7870 XT GPU - Reballing With DIY Tools

[@ExilesGate]

The level of skill to do this by eye is exceptional!

[@marceloQ7530]

Excellent work! I really like how you do your tools, I'm also planning to build a machine for homemade rework, I hope to be able to do such professional work as is your case, congratulations!

[@FoodKart]

*One Word, GENIUS.* I am a Tech enthusiast and my Sapphire 7870 XT is giving me no display and was searching around and i landed here. If you know a solution to my problem, then do assist me too :D

[@NikTelio]

Hello, probably BGA cracks, i think you need to do a reflow, watch this video kzbin.info/www/bejne/fIabZaR9iMl4Y9U

[@Bebe7512]

You have tools but you have skills too :). Great work!

[@NikTelio]

Thank you :)

[@theotherotherBrian]

Excellent video on this process!

[@oxfordelectronics1351]

Amazing work!

[@NikTelio]

Thank you

[@BurtTMacklin-fbi]

at 6:45, are you applying solder or some of that low-temper solder removal stuff? Which tip (exact model) are you using and what's your soldering station? Finally can you do a video on motherboard LGA reball/replacement? Thanks!

[@NikTelio]

i'm using leaded solder sn63pb37, for the soldering station and the tip watch this video kzbin.info/www/bejne/jWardnZ_ZrFmmsk , i would need a bigger rework station to repair big boards like pc motherboards

[@BurtTMacklin-fbi]

Is there a difference between leaded and unleaded solder for rework? Are there instructions with the T12 build kit from aliexpress/banggood?

[@NikTelio]

leadfree solder replaced the old leaded solder not because it is better but because the lead is toxic. leaded solder has better mechanical properties and can tolerate thermal stress. one more difference is the melt temp, leaded solder sn63pb37 melt temp is 185°C , leadfree solder 220°C, and when using leaded solder the rework temp is lower and you don't stress the motherboard and other electronic components. i bought my t12 controller on ebay and there was no instructions, i don't know about aliexpress/banggood

[@RAJESHKUMAR-kw2zp]

Good work sir

[@ACCOUNTANTB]

Great handmade work but question - isnt it cheaper buying another redeon ?

[@fantasiusman]

Grazie mille!!! thanks so much!! you can tell me where to buy stencil for gpu laptop and what type of paste flux is better for you. sorry for my english. thanks . Giuseppe.

[@NikTelio]

Hi Giuseppe, to find the stencil that you need you must search the chip code on ebay and on the stencil you will find the solder ball size, i'm using warton metals future hf rework jelly for many years because it does a good job and leaves very little residue, amtech nc 559 is also good for reballing

[@fantasiusman]

thank so much, and nice to meet you, where do you live? you make this for work or for hobby ?

[@NikTelio]

I live in Greece and i repair computers as a hobby but i also make some money from it :)

[@juliantorresrubio4637]

Que gran trabajo muy professional excelentes videos ! Saludos desde colombia

[@NikTelio]

Thank you, hello Colombia greeting from Greece

[@abeldiaz6684]

Great work!

[@NikTelio]

Thanks

[@c4k3t0otz6]

amazing work, ever think to try and replace the vram or see if it is upgradeable to a larger size by replacing all the chips with larger capacity ones?

[@NikTelio]

Thank you. if the gpu and bios support larger capacity memory chips then it is possible to do this.

[@Ahmed-Egyptian]

Hello Nik :), ty really for ur all BGA reballing videos really inspired me. in 18:10 this tool i cant find one like it , can u share me link for it or where i can find it .my regards :)

[@NikTelio]

Hello, this tool is custom made , i bought this pcb holder and modified it. www.ebay.com/itm/PCB-Fixtures-Repairing-Circuit-Boards-Metal-Holder-for-iPhone-Samsung/401783706405?hash=item5d8c2cd325:g:cwkAAOSw7A9c~gN3

[@Joligo60]

Hi Nik. How do you make the chip not present a bubble in the welding process? You put plate and chip in a greenhouse before? Hugs.

[@NikTelio]

Hi, watch this video kzbin.info/www/bejne/p5fYc4tph6-VmcU

[@Joligo60]

Nik Telio I watched it. Great. Thanks a lot.

[@williamzhou1286]

Hi, great rework station and video! I was just wondering what you hooked up the bottom IR preheater to in order to power it?

[@NikTelio]

Thank you. the bottom and the top heater are connected on 2 ssr (relays) and the power source is 220v, the pid controller controls the relays, this is the entire basic circuit, it is very simple

[@williamzhou1286]

Thank you for the response! it would be ok to use something like a variac to control voltage of the 220v IR plate in the USA (110v) right?

[@NikTelio]

Hi, i would use an electronic step up transformer 110 --> 220 volt 2000watt to power the rework station and a dimmer to control the bottom heater or a thermostat

[@williamzhou1286]

Excellent, I'll do that then

[@SUCRA]

Hey Nik, may I use a tiny cut of this video and the reflow video as examples on a video I'm making?

[@NikTelio]

Hello, yes you can use it. Regards

[@SUCRA]

@@NikTelio That's very kind, thank you.

[@wansegamat3064]

I wish i can do this .. good video

[@rattlehead999]

Where did you get the heat stencil?

[@geek4001]

I have a motherboard that needs processor socket replaced because some pins are broken. I do have a lga new socket. Can i purchase two small ceramic heating plates, one bottom one up and heat the chip while monitoring the temperature and try to remove the damaged socket? Which temperature will it move?

[@NikTelio]

Hello, this would not be easy, you have to monitor the temp on bottom heater , the top heater and the board temp, the bottom heater needs to be a big heater (size and watts) because is the one that delivers the most heat, the top heater helps a little to rise the board temp to the solder melting point 220°C and when you reach the liquid state...one wrong move and other components like small capacitors could fall of or move and the motherboard is useless :/

[@geek4001]

@@NikTelio too bad i removed the socket. I used a 100w ceramic heater in bottom. And used the hot air rework station to heat the socket and everything was fine until i removed the socket carelessly and all the resistors inside the socket went flying. I am going to resolder all the resistors and buy better ceramic heater for bottom and up. And buy a themorcouple. Do you think without heat controller and just with thermocouple i can grt the new bga sockst inplace?

[@GmRb79]

so the lines are because of a cracked solder joint? nothing to do with vram?

[@NikTelio]

if you see the lines and artifacts during POST and PC can not load the drivers or even crashes then probably the issue is the GPU and not the VRAM

[@spidermcgavenport]

Epically impressive skills, would you be willing to try your expertise with a Peltier cooling Tec/Teg system. You know thermal differentials, perhaps you can make one work properly without condensation!

[@spidermcgavenport]

@189°C that's not an ordinary bought from the brick and mortar store grill! Or is it?

[@spidermcgavenport]

Wow @230°C damn impressive too hold that temperature steady.

[@ArchAngelAzrael]

I know you love to do reball and share the videos. But can you tell us how to to know if a gpu chip is dead or is the chip is OK ? How to test it ?

[@NikTelio]

i also don't know if a chip is ok or dead, to inspect the BGA and chip and see if there are cracks you need a BGA scope and an Xray machine, very expensive tools, and none of us diy "technicians" have these tools, i do the reballing and say a few prayers and if it works i'm happy :) lol

[@benvarela134]

Very impressed...

[@mypeeps1965]

how do you know its a reballing issue and not a bad chip? Love your vids, thank you!

[@NikTelio]

without an Xray machine and a bga scope i can't know, i do the reballing and then i test the gpu, sometimes it doesn't work but i don;t mind :)

[@mypeeps1965]

Thank you for the reply. Your quality and workmanship are excellent!

[@NikTelio]

Thank you, you should have seen me when i was still learning reballing lol i did so many stupid things lol

[@originalmartialartsmovies2314]

what is the purpose of reballing?

[@donnymahmud9447]

can u show how to use profile for reballing ps3 RSX and CELLBE with your DIY BGA Rework,,,,tks

[@NikTelio]

Hello, i have never reballed a ps3 :(

[@granules2919]

nice background music

[@alexrodrigez1849]

so it mean any chips can repair just like new?

[@rattlehead999]

How do you know if the chip is aligned?

[@ghtrcvb]

indication red and blue colour of the numerals-temperature,what colour what temperature shows? (top-bottom) on your DIY HomeMade BGA Rework Station.

[@NikTelio]

the top temp gadget (red) shows the top heater temp and the other gadget (blue) shows the bottom hater temp

[@ghtrcvb]

Nik Telio thank!

[@koford]

Now i havent seen the end of video (I will), just at this time i wanted to write: did you notice at 22:22 when you placed the GPU and moved the rail, bump i saw a solder ball jumped off and trilled off. !!!

[@koford]

Allright, i assume you saw that and replaced it. After see you remove stencil and paused. looks good. !! heh

[@NikTelio]

you are the first one that noticed that :) i saw it and added the solder ball and at 22:45 you can see that the ball is there :)

[@arhansoylu]

you are so good..

[@realMrVent]

Did you jerry-rig some laptop coolers to your CPU radiator? Why would you do that?

[@NikTelio]

they are for cooling the northbridge and the VRM's

[@Joligo60]

Show. Fantastic. Very good.

[@NikTelio]

Thank you

[@lazar2175]

How would you go about changing a socket on a motherboard?

[@NikTelio]

pc motherboards require a more powerful and bigger size bottom heater, i replaced one LGA 775 socket once but my station was reaching his limits

[@geek4001]

Do you mean bigger watt heater? I gotta motherboard that needs replacement with minimal budget. Will a lower heater and one upper heater with themometer do the job? What watts do you recommend. And the resistors inside the socket. Will the tape protect them from popping up?

[@theparoc90]

where do you get your stencils? i'm actually looking for a r9 280x/hd 7970 stencil too!

[@FixDaily]

The lateral laptop fans are there to cooldown the board or the bottom heater?

[@NikTelio]

Hi, the main purpose is to cool the board but at the same time they cool also the bottom heater

[@FixDaily]

Thank you that's exactly what i wanted to know

[@BurtTMacklin-fbi]

oh yeah, what temperature do you use to remove the solder at 6:45?

[@NikTelio]

i set the temp to 285°C

[@JonnyBrek]

Hi Nik. How are you? And so much so that you don't put video. I hope everything is OK. Finally I managed to find a housing for the creation of the rework machine. Except that I haven't found that little circuit that manages the operation yet. I have all the rest. Do you know how to do it to get it for me? It would be very nice if I made a video of the assembly of the machine. But I know it's an absurd request. With all its connections.

[@RidvanKahveci]

Doesnt stencil swell in middle why getting hot? Mine are swell so much

[@NikTelio]

good quality stencils do not bend during the heating process

[@RidvanKahveci]

İ bought them from aliexpress, its no chance to understand how quality it is

Hello, at home you can try to reflow your graphics card, is the easiest way to repair it , watch this video kzbin.info/www/bejne/fIabZaR9iMl4Y9U

[@k2050101]

taking a gas mask when you reworking bga, afterall, health is important for doing everything.

[@NikTelio]

:) thanks , i have room ventilation to extract the fumes

[@k2050101]

and I have try, if the solder ball smaller than 0.7, you dont have to clean with solder wire. you just using solderimg iron drag lead solder all over. Because some PCBA quality is bad, even gets enough temprature preheating, It still get pad broken

[@k2050101]

P. S. others video on youtube People just using their finger to wire flux without any glove let me feeling disgusted. becaus we using our hand to do is not just about repair, we have to eating. cooking etc. I likes your good video show.

[@NikTelio]

fluxes contain chemicals and the skin absorbs them , i would not do this

[@NikTelio]

yes when the soldering iron temp is to high, for example ~400°C then you burn the pcb and the pads brake, tat is why i set my bga soldering iron at 285°C max 320°C
