Both repairs involve astronauts unfastening dozens of tiny screws to replace some circuit boards on each of the instruments – all while wearing bulky spacesuit gloves. Such a feat has never been attempted before in space.
The astronauts will also have to cut through metal layers to reach the circuit boards, creating sharp edges that could be hazardous to spacesuits.

Ok; that sounds very difficult and impressive, and I don't want to take away from the feat, but I do think it needs some clarification.
What feat has never been attempted before...he unscrewing, the replacement of a circuit board, or the fact that it's tiny? And what is considered tiny when you are wearing a spacesuit?
