HowTo: How to photo etch a PCB
( Russell Watson)
Step 3 : Transparence
|
| | You will need to have a transparence from a PCB program. I took a copy of my image to a local office supply store and had two transparencies photocopied. I did not like how one looked because I could see through the traces, so I taped two together. When making the image, you want to have the printed side down on a board. I made reference to this by placing the TOP backward on the paper. Make sure when you print your image that it will be the way you want it when you flip the transparence around.
Here is my transparence. You will also need a piece of glass for a weight, as it holds down the transparence on the board so that no light passes underneath the transparence.
