Having this note is because that a pcb should be free from moisture prior to processing. Moisture can migrate into tiny holes, which will influence the performance of this PCB.

It is for gettimg rid of moisture, probably to keep the steam
from pushing BGAs or CSP packages off the board.

In order to avoid copper oxide and moisture make solderability poor.
It is also the resaon PCBs are sealed in plastic in storage for production.
