Board holding jigs and preheating equipment. A jig holds a board steady so both hands are free; a preheater brings the whole board up from underneath so your hot air only has to supply the difference.

How to choose Board Holder & Preheater
Preheating is not optional on large chips. Blasting one cold area to reflow temperature while the rest of the board stays cool is what bows laminate and cracks joints away from where you were working. If you remove underfilled chips, a preheater pays for itself in boards not ruined.
Board Holder & Preheater frequently asked questions
Why preheat a board?
So your hot air only supplies the difference rather than all of it. Heating one cold area to reflow temperature while the rest stays cool is what warps laminate and cracks joints elsewhere on the board.
Do I need a jig as well as a preheater?
They do different jobs. A jig holds the board steady for soldering; a preheater controls its temperature. Most board-level benches end up with both.
