You need someone with a hot air smt solder rework station - blows very
hot air through varied sizes of nozzles depending on the accuracy required.I
have an Aoyue 909 which has been very useful. If using a different method
like a normal hot air gun (paint stripper) or the oven method beware of
components which are soldered through the board - these can fall off
altogether if not supported. You can improve your accuracy with a hot air
gun by masking all but the targeted area with metal foil - it's difficult
without a rework station though.
