Connect Arduino UNO board to your computer. Get you ferric chloride FeCl3 powder and mix with water in your plastic container. If any track broken, use permanent marker pen to draw a track with carefully. Before you start etching, check all the tracks. Make sure your copper board is as clean as possible. Now use a laminator to transfer the toner to the glossy paper to the PCB. Now set the laminating machine temperature to its maximum value. I changed potentiometer of laminator for increment of laminator temperature. So this laminator is slightly modified for the toner transfer method. For the toner transfer method, required temperature is C F. Now put bottom layout paper on the bottom side of the PCB. After cutting the paper, put this top layout on the top side of the PCB. You need to mirror image of the top layer layout.Ĭut the copper board according PCB layout size. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. I'm using laminator for the toner transfer method. In this instructable, I will show you how to make your very own Arduino Nano.
