| I have owned a Jovy RE-7500 for about a month now. I have managed to do many reballs on many different chip types (nVidia, ATi, Intel, etc) many with success and quite a few failures (popcorning, temperature issues, etc). With regards to nVidia GPU issues, I have managed to successfully reflow the chipsets from the HP DV6000 (6150) and DV9000 (8400GS & 8600GS) series. I do have some concerns when it comes to simply reflowing BGA chips as I have read about so many cases where the problem resurfaces within a 1 - 3 moth period. I do not use lead free solder as this is usually the cause of the faults in the first place, im sticking to Sn63Pb37. I still face many issues as I have only owned the RE-7500 for a short period of time, but I have become much more confident the more I experiment, it is simply 'trial and error'.If you have any concerns, get in touch with me so I can share my experiences and hopefully help! |
