    nx6110 southbridge reflow

    I have a HP NX6110 that freezes on splash screen unless i push down on the touchpad.After reading on a few forums i am led to believe the southbridge needs reflowing but ive also read that this chip is more sensitive to high temperatures than a standard bga chip.can anyone tell me if there are any special precautions i have to take with this chip or is it just the same process as a standard gpu reflow.

    thanks

    Same thing really. Just use a lot of flux and you'll be fine.

      Well , reflow will help , but not for a long. It can work a week or a year. Only reballing can warant proper working.
      Cheers

        I believe these are a little different - similar to the T41 problems with the board flexing. I've had a few NX series with the same issue and a hot air gun does the trick nicely. The GPU reflows are a different beast where solder needs to reach liquidus.

          what sort of success rate does reballing have in general.i have just invested in a reflow machine but never actually reballed anything as yet.would it not be better to buy one of the vga chips off ebay with the balls already fitted?

            yes it would but the only ones ive ever seen are Chinese ones and these are rarely new and often refurbished. If you can find a local supplier who you could trust then yes, that would be much better.

              hi, i have the same nx6110 freezing problem. I try to reflow and then notebook won't turn ON, i reflow again and i got power on, but with the same issue. Pressing the case around touchpad freeze for a sec on 2 sec. Can you gave me any tip? Currently i don't have infrared soldering machine to remove the chip-

                Hello all,

                I am experimenting a bit with reflowing larger components - ideally I'd like to reflow a PS4 APU or a GPU for example.

                I know it's impossible to reflow such large components with just hot air so I bought a pre-heating plate, T-8280 classic Chinese machine, which seems to be working fine besides it's a little slow, which shouldn't be a big deal.

                Now, my hot air station is a Aoyue 852A++ and I feel it's a bit weak when used with larger nozzle. I tried reflowing a laptop chipset using one of those large, rectangular, nozzles and I failed miserably,...

                Concerns before attempting a Reflow of Laptop's GPU
                by Mr_Nada
                I saw some posts at one point talking about doing a reflow but I couldn't find them again so I thought that I would post this here.

                I plan on reflowing the GPU of this old HP DV2500 laptop but I want to go over what I have and the steps I have to take to guarantee it will come out fine.

                I have a Yihua 8786D 2in1 Rework station, flux (just some paste that I got from an old Radioshack kit), a couple rolls of Kapton tape and a $15 Thermometer +probe (a TM902C from EMR shielding Solutions if its important).
                • The paper that came with the thermometer states that the probe

                Google Pixel 5 - Proximity Sensor Issues - Reflow/Replacement procedure tipps wanted
                by groomit
                Hi,
                I just replaced the battery on a Google Pixel 5.
                After that the proximity sensor isn't functioning properly any more. It is constantly activated. So when playing a voice message on Whatsapp, the Screen instantly turns off.
                Checking with a sensor app I can verify weird behavior of the sensor. It is triggered when nothing is near and sometimes works correctly when squeezing the phone next to the sensor hole.
                The rubber seal is on again (as mentioned in various suggestions in other forums).

                This smells like a cold or broken solder joint. So I'd like to reflow...

                I have attempted all sumed very few reflow processes, and i need to make it better, how do you make yours to have sureness that the balls are really fully reflowed? My temptation was always to do "the slight move" touching very gently an angle, but due to some cases, but maybe 100%, where the previously half working device became totally shut off, i finally understood that the damn "move" makes the balls shorted, so what do you suggest?
                Thanks!.. Muchas gracias.....
