Once you have exposed your PCB to the light source you will want to quickly add it to the developer. The board will still have a green color to it, but you will notice a faint yellow color showing your design. To develop the board place 1 part developer to 10 parts warm water in a plastic container. Gently rock the container back and forth.
Step 3 Expose the Presensitized Circuit Board to UV Light. Place the printed transparency on the elevated plastic about 10 inches above the LEDs. The ink should be facing up towards the sky. While the room is somewhat dark, peel the white film off the presensitized circuit board to expose the photoresist.
