My graphics card got dead so i approached service center and they said chip is ok but reballing is need. i couldn't understood exactly but thought it is something relating to chip.
Even after this reballing will it last enough. service charge they put is something like 12$(750rs)

Wikipedia is a good place to look

Reballing

and below that section there is the "Results" which say "Properly carried out rework restores the functionality of the reworked assembly, and its subsequent lifetime should not significantly be affected"
