Editing PCB Etching Tutorial

'''DIY PCB Etching : Using Chemicals'''

Chances are you've probably seen a PCB before and it might of looked a little something like this

[Insert a picture of an example of a PCB maybe a Raspberry Pi or an Arduino etc]

The most important part of a PCB is the ''traces'' which connect the components to each other.
These ''traces'' made in a CAD program for PCBs like : Eagle CAD , KiCAD etc

[Insert Picture of traces here]

This tutorial will show you how to make a simple single sided PCB using a chemical method.
In summary the traces will be transferred and covered in a solid copper board , then the parts of copper not needed will stay expoxed.
Finally the parts not needed will be removed with chemicals.

'''Materials Needed'''

- Single sided copper PCB board
- Traces (should already have been designed on some CAD program)
- Glossy Printer Paper (to print the traces on)
- Iron 
-Ferric Chloride Solution (to dissolve the copper from the board)
- WetorDry paper
- Container to put PCB in with chemical solution

'''Steps'''

1) Preparing the Copper Board: Clean It

Make sure to clean any junk from the copper board before beginning the process!

  - Use WetorDry paper / fine sand paper to clean the PCB under water until it turns pink
  - Wipe off water with a clean towel
  - Use acetone to remove oils from PCB

2) Printing the Traces:

Grab your printer and print the traces onto the glossy printer paper 
     - be sure traces are nice and thick
     -  check the preferences for a "no scaling"
     - Design must be mirrored
     - Only use black ink
     - Print at the highest resolution possible


3) Transferring the Traces to the PCB:

   - Press down the glossy paper with the design onto the copper PCB 
   - Use a hot iron to press down glossy paper to the PCB [INSERT PIC HERE OF IRON PRESSED]
