  • what the hell is with the crappy music. Its not the hard core random techno I'm use to on these videos.

  • Comment removed

  • go with hotair people... infrared systems are crap.

  • Does anyone know the song?

  • @jamaldjabou

    The PDR system works totally different compared to the Jovy. Also, PDR is a good quality system while Jovy is a very cheap low cost system.

    PDR is a short wave IR system with focussing optics, Jovy is a medium wavelength system.

    It's FAR AWAY from being similar.

  • How much to do my PS3?

  • 3. If you heat a PBGA like the chipset processor on soldering temperature by an IR system an you have an electrolytic capacitor directly beside, then the capacitor will blow. Conclusion: The PBGA was not hot - the video is a fake!

    4. The Jovy equipment is a cheap copy of ERSA Rework systems - and NOT reversed!

  • 1. What do you think? The board temperature is at 105 C and then they remove the BGA?? Nonsense! This process video is a fake!

    2. Smoke is normal - can be from by remaining flux residues. But take a close look on this video! The smoke neither comes from the chip and nor from the board. It comes from somewhere in front of the PCB table! So the smoke is a fake! Additionally you can see a cut in the video and it suddenly starts to smoke where was no smoke before.

  • @JSchreck31 the pcb is 105 is just the motherboard not the chipset. they have to preheat the motherboard at 100 to 120 then the ir lamp at 220 but they didn't show that, plus south bridge is very easy to remove and this is using lead as it's quite old

    and lead melts at 189c

  • @2handtrailers

    Come on - do you really think that the TC beside the PBGA measures a totally different temperature than the temperature of the PBGA??

    If they show a process then they should show the WHOLE process and not just the half.

    They also don't use an IR lamp, they use a medium wavelength IR heater. And this heater has a diffuse heating field and this means that it heats up also the area around the PBGA. One more proof that the TC should read a higher temperature.

  • It looks like that the ERSA Tools equipments originates from this model !

  • @tbn0307

    Be sure that the ERSA rework systems are the original systems. Jovy copied ERSA.

  • For a start this video shows removal of the SOUTH-bridge, not the North-bridge as the intro title reads.

    Also, removal of the battery probably wouldn't be a bad idea before you start desoldering things

    And last but probably more importantly - what's up with the smoke? I hope that's flux burning off and not something else....

  • @Tda7000 You sound like you know your stuff... Can you recommend a good BGA station for under $2K? I have been doing oven reflows for a while now and want to go legit but there are so many confusing choices out there.

  • @AlabamaRiverMan Wow, my previous comment is 2 years old!

    First off just want to say, the part about the flux is definitely stupid, of course the smoke is the flux burning off, this is not an issue!

    Unfortunately I don't have one of these BGA rework stations yet, so I can't give any specific recommendation. I would advise you to read online reviews and check other Youtube videos - There seem to be cheap systems around on eBay etc which work pretty well.

  • @AlabamaRiverMan

    The main thing I think it comes down to is power, most machines list a maximum IC size they can rework. Make sure this is adequate for your needs.

    Practice well the techniques, whichever machine you get. Do a reballing on an old motherboard, graphics card, whatever, and make sure it still works afterwards. Reballing is harder (but results are better) than a reflow.

  • @Tda7000 Thanks for the reply. I want to purchase a rework station soon. Gotta come up with a little more cash first. I'll probably buy it from thebgastore. And another question about what to do with this thing. What is the bread and butter of this business? I see a lot of these machines for sale that include templates for xbox 360... are people still making money reflowing these things?

  • @AlabamaRiverMan Yeah I would say so. PS3 as well (but it's more difficult to do) and then there's quite a few models of laptops\GPUs which have issues.

    And who knows what the next generation of consoles will be like...

  • @Tda7000

    So what about success rate using a BGA machine... Someone posted in another area that they only have about a 50% success rate reballing. Also... I am reflowing dv6000 laptops now that have the nvidia issue. My success rate is about 90%. Could I reasonably expect better and longer term results with a BGA machine?

  • @AlabamaRiverMan You should have a high success rate if you know what you're doing, and understand the limitations of whichever machine you're using.

    For example If your heating profile is bad, or the pre-heater is too small you can warp the board, cook the IC or cause other problems.

    And of course with nvidia GPUs for example, not all can be fixed by a reball, as they just fail and the whole IC needs to be replaced.

  • @Tda7000 Thanks for the reply. I had thought it may be easier to replace the nvidia chips on the laptops I work on. I see them for sale here and there for around $20/$25 or so.

    The machine I am looking at is the bauer bga v4 station. I still need to do a little more research before I plunk down all that cash for one

  • I have to agree with the smoking board sentiment which may unnecessarily stress the board (let alone the part. I would like to have seen a closer view of the pads of this board after the part was lifted off. Not to say that your system does not work, but perhaps for different applications.

  • @eclectro smoke is just burned flux, it's totally normal and safe

  • smoking board with a "professional station"... =_="

  • Music sucks and this is a slow process, I could do an easy board like the one shown in half the time with a hot air system

  • Very Good and efficient

  • @Raheeeeb

    Very good and efficient is different....
