I haven't seen the MBA board, so my answer will be more generic. If the memory is soldered onto the board (and we build h/w where we solder flash chips on mother boardboards for differnet deployments - expensive routers!), to replace/upgrade/or modify those chips, we send them to factory. PreciousPrecision soldering is required, it is not to be done at home (too fine a work for home, unless you have done this same exact work before and done it well everytime).

Even after factory re-work, some boards/assembly simply failsfail (shorted etc). Definitely not worth the risk unless you have direct access to a mother board assembly factory and someone does it for you over there.
