What does a hot air rework station do that a soldering iron cannot?

Select one answer.

• It presses a hot tip onto one joint at a time to heat it precisely, the same way an ordinary iron does but with a bigger tip.
• It reflows a whole package at once with a non-contact stream of hot air, heating all of a part's joints together.
• It cuts the board to remove a part.
• It glues components down.
