Clean the PCB with a scotch pad or fine sandpaper
When the board is shiny, use acetone to remove any oil or grease on the board
Transfer Image 1.Run the transparency through the laser printer twice to produce better transfer. 2.Tape the printed transparency on to the a cleaned PCB board. 3.Heat a hobby iron. With light pressure, iron the transparency onto the copper. 4.After the board has cooled, peel off the transparency. 5.Use Sharpie to complete image transfer

After the board has cooled, peel off the transparency.
Precaution Etching Solution may leave stain on skin and utensils. The use of rubber gloves is recommended. Avoid prolonged or repeated breathing of vapor or contact with skin.
Develop PCB 1.Ferric Chloride is used to remove the copper not protected by the toner. 2.Place the printed board into a container with a lid and pour about ¼” of the acid solution over the board. 3.Secure the lid and using a swirling motion, agitate the solution for 15 minutes to 30 minutes until the unwanted copper is removed. 4.After the excess copper is removed, pour water over the board to halt the etching process. 5. Dispose the left over chemical properly. (Include the chemical rinsed off with water)
