3dfx Voodoo 3 2000 - My first attempt to fix a BGA chip!
Рет қаралды 12,825
Күн бұрынA Voodoo 3 2000 AGP has been damaged by a sharp object right below the heatsink. Most likely, someone tried to get the heatsink off and in the process, damaged the BGA substrate. I will try to fix this card today, but I feel like I am taking on a project that is way above my capabilities. Let's see if will be able to fix this iconic graphics card!

An amazing attempt - particularly for being the first one. You'll be Rossman-level in no time! Some pointers from someone who also doesn't have a great deal of success with BGA, so please feel free to ignore :) 1. Get a laser thermometer. You need to be able to ascertain the temps on the PCB as precisely as possible. Remember that laser ones rely on IR though and each material is different. But I think it'll do 2. Do rely on the pre-heater as much as you can. 150C on the PCB are fine for pre-heating. If leaded solder (that is a leaded solder card, pre-2000?) you might just need a little extra from your hot air station. Do leave the card to "soak" for a minute or so once it reaches the desired temperature and start with hot air a bit far away. Those large things do take time to rise in temperature so don't be too concerned if it takes some time. 3. Use the largest tip you have for cleaning the pads. Some of those pads will be connected to ground/power. Heat from a small tip might be sucked away quickly, resulting in what you observed when the pads did not want to take solder (unless it was a bad pad). The wick will also wick heat away, Ideally you want to use a segment only. Make sure the card is still on the pre-heater when cleaning the pads. "What's for dinner tonight?" "what are the options?" "Ice-cream or Frozen PCB" "I'll get the PCB with some solder balls sprinkled on it" :) Once again, an amazing attempt!

Haha, that last bit made me laugh 😂... And thanks for all your valuable hints! I will definitely try to follow those. I don't have a laser thermometer, but maybe the thermal camera will do as well. I probably should have been a bit more patient with letting the card soak on the pre-heater. I'll try this again once I get the new hot air station. Thanks Tony for your input!
@tony359 4 ай бұрын
@@bitsundbolts In theory the thermal camera should work but I found a handheld laser one more accurate and practical. They're not expensive. Can be used in the kitchen too :) Just remember the laser is only a guide. The IR sensor is a cone and it matches the laser pointer only at a specific distance.

I seem to recall another youtuber with a modicum of success in BGA repair having a source of cold air on hand; think it was actually plumbed into their heating rig in case of emergency - but sure they also mentioned it being a handy trick for if you have just a couple of recalcitrant joints ... will see if I can find the source, I think it was a PS5 repair.

Well like he said, there are no stencils available for these Voodoo 3 chips at present. There are upsides though - not many balls compared to modern parts, and no reballing jig required. I'm in the same situation where I need to reball 2x Voodoo banshee cards and a Voodoo 3. I don't think that's worth buying the stencil jig for and I can afford 20 minutes per chip. Thanks BuB for showing how it's done and the issues you came across with the solder ball sizes, that should help me in my repair attempts.

I've got a GA586DX-Board laying around, changed the northbridge and the southbridge, repaired soldermask and ripped pads. Never got it working again. On the other hand, i recently replaced a X570-southbridge on an AM4-board and it worked again. Even with the factory unleaded solderballs. One day you lose, the other day you win. Simple as that. Just keep on going and try to improve! Maybe collect some other V3-cards and swap stuff around. If it's not working, it's for science and practice!

For cleaning up large PCBs with ground planes and being able to wick up solder, I'd recommend useing a "flat blade" tip and cutting a section of solder wick to be slightly larger than the width of the blade tip. These tips are quite large and will have a lot of thermal mass, and by using a small piece of wick you don't have to have the entire copper mass of the entire spool drawing away heat. Just place the wick piece down, blade on top, and use it like a mop with gentle pressure to push it around. When the wick is saturated, pick it off with some tweezers and get another piece.

Nail polish remover (acetone free), is the gentlest thing that I found softens the remaining heatsink glue on 3dfx cards , for cleaning without damaging even the writing on the chip. Spread a few drops with a cotton-bud / Q-tip to make a small puddle only on the glue, and after a few seconds, start gently scraping the edges and softened surface layer of the glue with a sharp blade. Add some more drops, spread, repeat. It doesn't penetrate to well, so you always have to soften the new layer that you expose. In under 30min. you'll have a pristine looking chip.
@bitsundbolts 4 ай бұрын
I have not tried nail polish remover. This is what I can imagine that you still have to go layer by layer. This glue is so hard - I doubt it will just soak the entire thing and you can easily peel it off. If I get another card that needs that, I'll try it. Thanks!

Personally when removing glued on heatsinks I apply hot air to the the middle of the heat sink until the glue starts to soften. Using a pair of tweezers inserted through the fins, apply a gentle twisting action. You will feel the glue give way and be able to lift the heatsink right off. Worst case the solder melts and chip and heatsink come off as one.

Maybe it'd make sense to use a linear halogen lamp with 500W rating so that airflow during the reball wouldn't be an issue? And I'd suggest to use Sn63Pb37 solder balls. It's an eutectic alloy with much lower melting point than the regular lead-free stuff. They're still available in the EU.

I've only ever successfully reballed ONE BGA chip so far. Which happened to be a VSA100 chip, for a Voodoo 4 clone I've been working on (along with somebody else). I tried using the hot air station at first, but I had similar problems with the solder balls "swimming" around, even with the lowest air flow, and a thinner layer of sticky flux paste. (I used a stencil to help place the balls in the first place, though, much easier.) In the end, I just carefully put the chip into the reflow oven (modified toaster oven), and that worked great. ;) Great first attempt, btw. I would probably have given up after seeing the damage to the chip.
@electronash 4 ай бұрын
I should mention that I've never owned a preheater. I've often thought about getting one, but it's very rare that I need to reball or reflow a BGA chip these days. I can see how a preheater would be a huge help, though. It's important to heat the PCB itself, as evenly as possible. Obviously with only the hot air (or even IR) at the top, it takes a long time to heat the entire chip, way before the solder balls start to melt, and then heat the pads on the card. I have seen people just put the entire card into the reflow oven, but that's an obvious risk of other components moving around, or caps and certain plastics melting. Most components would have been through the reflow oven at the factory anyway, but it's a bit harder to get the temperature just right when you're dealing with a modified £30 toaster oven. lol
@SidneyCritic 4 ай бұрын
Probably a long shot, but the way the balls were columns, it looks like something was holding the chip up. The balls can correct some flatness issues, but generally BGAs rely on flat surfaces, ie, check with a ruler across surfaces and damaged corners to see if there is a high spot keeping inner balls from reaching down to the PCB. Current you have nothing to lose pulling memory chips, etc, and resoldering them properly, so I would just keep trying.

For removing the glue you can heat the cooler/chip combo at about 100C and then use the screwdriver. The same method is used in PS3's RSX. For the glue that remains on the chip and cooler you can use acetone. It will take a while, but there will be no scratches from the knife. Or you can use the knife for the bulk of the glue and then the acetone when the glue will be thinner.

I feel like I'm repeating myself but wow, that was some mighty impressive work there again! It's a shame you couldn't revive this card (yet?), but it looks like you did gain a lot of experience (I certainly did just from watching!) and even with perfect methods, your chances of success were pretty slim to begin with. I wasn't optimistic from the outset, but when I saw that some amateur had already tampered with it (beyond just attempting to take the heatsink off to re-use it somewhere else), my heart sank even further, as it meant that it probably had an issue beyond the absuse it was subjected to. As Captain Picard expressed so pointedly in S02E21 of my Bible, "it is possible to commit no mistakes and still lose". I think there is a minuscule chance of the last issue being that the undersized solder balls prevented proper connectivity, so it may be worth having another go at it with bigger ones. I really hate the fact that one cannot check below SMD components. We need BGA to PGA conversion kits!😅 Anyway, good luck in case you decide to go through the tedious re-balling process once more! Also, good luck for the other two cards! 🤞🏻 I'm quite optimistic about the Kyro.

Für das Reballing würde eine Reballing Maske verwenden. Dann sind die Kügelchen fixiert und können verflüssigt werden. Dann den Chip aufsetzen und mit genügend Boardtemp und heißer Luft auflöten. Möglich, dass einige Kügelchen keinen Kontakt haben oder leicht neben dem Pad liegen. Du kannst ja einen zweiten Versuch starten. Chip wieder runter, die Kontaktflächen prüfen und alles noch einmal reballen und verlöten.

Wow, that was a really interesting repair attempt. I've never worked with BGA, but it looks surprisingly easier than I expected, just a lot more tedious. At least hand reballing anyway. From what I've seen of Louis Rossmann's repairs, it's not even 100% guaranteed to work even when you've got one of those huge BGA soldering machines with a fancy alignment camera. It is definitely possible though. I know you've got the patience, all you need is a little more practice, and I'm sure a new hot air station would help! My suggestion would be to find something very cheap and plentiful with a BGA chip that you can practice on. Obviously something that you know works. Like if you can find a pile of those old Linksys routers, just check if they've got a BGA chip inside and they boot up. Not sure if they've got a serial console that you can solder a pin header onto and plug a USB serial cable into to get access to the CLI so you can see it boot.
@bitsundbolts 4 ай бұрын
That's a good idea! I don't mind practising on more devices and the test afterwards would be essential to verify and assess a successful BGA replacement.

The best way to get rid of that thermal glue is to just water it with some 70% IPA. Just keep adding more IPA over enough time and then you can just peel it off with your fingers. You can score the glue a bit to speed up the process but be careful not to scratch the chip.

Haha, thanks! Oh, it's ok even if the card didn't work. I'm happy that I could get the chip off, reball it, and put it back in the card! The experience will definitely help me the next time I try such a repair! Thanks for watching!

Loved my Prophet 4500 back in the day until I killed it with a volt mod + pushing the overclock. Good times, then I splurged on a 9700 Pro. Ugh so expensive back then...
@bitsundbolts 4 ай бұрын
I couldn't afford the 9700 Pro. I don't remember if I got just the regular 9500 or the Pro, but I know that I couldn't unlock the additional 4 render pipelines. Graphical glitches everywhere. Ahh, I was disappointed, but the card did serve me well for some time. The Kyro II will be new to me.

hi, i have "atten st-862d" at home and "quick 861dw" at work both are works similar, You can take whatever you want from either of them, but I recommend to you buy together 45 degree bent nozzle set with hot air station

It's possible that there's also a VRAM issue. Depending on which memory IC is dead, it can also cause a no detect error. Edit: however, my money is still on the 3dfx chip itself, it's probably toast. There's a seller on a popular forum (cpu world) who still has a few of these, so you could source one from him.
@donpalmera 4 ай бұрын
I would guess the main chip or something else was already dead from the start. Someone else had a "I've been some videos of how to reflow a GPU on youtube, I'm qualified now" attempt at repairing it before you and they gave up when they cracked the corner of the BGA.
@bitsundbolts 4 ай бұрын
That could be a possibility. Oh well, then all I get from this card is BGA soldering training, but that's ok. I will give it one more shot with the new hot air station.

You're absolutely right! I think the Kyro II will smoke any GeForce 256 except for T&L. I haven't done a lot of research yet, but this is what I believe is going to happen in terms of performance. I'm looking forward to hopefully fixing the Kyro II!

Your skills are so impressive, like how was that your first (I guess second if the destroyed training chip counts) attempt at this… Bummer that it didn’t work out in the end, maybe that chip was already dead before you even touched it.
@bitsundbolts 4 ай бұрын
Thank you! You're right, it could be that the chip was already dead. I'll try once more when I get a better hot air station. If the chip is dead, then I'll get more practice. Want to become really good at this without buying a reflow station 😅

That looks like a lab plate, not a preheater. I use a lab plate to solder new PCBs with solder paste but I wouldnt use it for preheating. It gets much hotter than a preheater but wastes alot of heat and can't really be worked over. You don't need a better heatgun, just a better method. Buy an infrared preheater with a heatgun holder bracket. Use a square diffuser nozzle on the heatgun you have now. this works for me on newer GPUs and newer GPUs have many layers, they are much harder to deal with

nice work, but I think that the 3dfx chip has gone to silicon heaven, for this kind of work you clearly need a BGA station, it is not possible without it, as you said in the video, if you find a damaged type of 3dfx card with a good 3dfx chip, you can try to rebal number 2 and I think that you will be successful 😉
@bitsundbolts 4 ай бұрын
Thanks! Yeah, I am not giving up. Although, I will give it another try. Once I get a better hot air station, I'll try once more. For one, to practice and I still have a little hope left. I just want to give it another try.
