hi, i own a small laptop repair shop in el salvador, central america. i have been fixing this issues with the classic hot air gun. i recently read a GREAT story from the inquirer explaining the cause of the nvidia bga problem. i must say that u guys are doing a great job giving your techiques to many of us who are interested in fixing this motherboards. my technique right now is the usual heating of the chip for about 90 seconds at aprox 150F ata a distance of maybe 2cms. then we place a copper piece for it to make contact with the heatsink. but as u may imagine the customers come back sometimes after 3 weeks, sometimes after 2 months. i have been web-searching a system to cool down the gpus and i found a thermoelectric cooling system wich uses a small plate with one hot side and one cold side (peltier cooling system), this morning i bought my first thermoelectric system at a price of $6 on ebay and will receive it in 7 days and i cant wait to receive it...i will certainly post the results here.
someone was asking for a website to buy the chips i found some in alibaba.com...i purchased 2 f500/f700 motherboards from them and im satisfied. |
