After circuits have been etched onto the board it passes through various chemical baths and is then washed and rinsed. Air drying in racks is both wasteful of time and space and hinders productivity.

   
 

Two air knives placed top and bottom on a mesh conveyor strips off water lodged in the channels and holes. The board is then passed through a heated chamber to “flash off” the final trace of moisture. Boards can then be transferred to the next stage of the manufacturing process immediately.
