Put the board in the developer ([[Equipment/PCB_etch_station#1st_Tank_-_Developer|tank A]]), at the moment the heater for the developer is broken { note: is this still true ? } so it takes longer than the 30 seconds. What you need to look for is all the copper is exposed when you check it. Only the tracks should be coloured (green with the uv exposure board).
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).


Note : the developer in tank A is from Mega Electronics, also sold through Rapid. It works well with photo pcb material from the same source. It does NOT work with Maplin photo material !
You may wish to give the board a rinse after this stage.
