Put the board in the developer ([[Equipment/PCB_etch_station#1st_Tank_-_Developer|tank A]]). Developer does not need to be heated to above room temperature to remain effective. Developing should take around 30 seconds to a minute or so - but check on the board to see when it is complete. All of the copper to be removed should be exposed, and only your tracks should remain coloured ( probably green for UV exposure board). | Put the board in the developer ([[Equipment/PCB_etch_station#1st_Tank_-_Developer|tank A]]).
