They use a special fixture to hold the chips in place and heat both sides at the same time. You need very special gear only available at a fab house. In any case SMT chips as densely laid out as these are can't be desoldered and new ones desoldered by hand. Definitely not worth the risk unless you have direct access to a mother board assembly factory and someone does it for you over there. Precision 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).Įven after factory re-work, some boards/assembly simply fail (shorted etc). to replace/upgrade/or modify those chips, we send them to factory. One user did ask in their forums if it was possible. This alone should tell you that it is something that should not be attempted by users who are not professionals. IFixit, who is a proponent of replacing everything in your system, does not provide a guide to replace the RAM (only the entire logic board, on which the RAM is soldered).
