This method is a lot easier than the other one i made and a lot quicker.
All you need is:
- sand paper (fine grit preferred) I used P400
- 0.8mm drill bit
- drill
- ammonium persulphate
- water
- dalo pen (etch resistant pen)

Step 1: PCB size, Drilling and drawing up

Firstly and most importantly, you need the PCB and the circuit diagram. Using the circuit diagram as a reference, select the size of the PCB that you want to use for the project. Once you have selected the size, tape the circuit diagram onto the PCB and using a 0.8mm drill bit, drill holes into the circuit board in their designated places, of course. Take of the circuit diagram but do not throw it away unless you have a copy. Once you have done that, using P400 sand paper, just smooth the PCB by rubbing the sand paper softly. When you are content with the smoothness (i.e. no bumps where you drilled the holes) copy the circuit diagram onto the PCB using an etch resistant pen (Dalo pen).
<p>After the iron,under the copper it's all black, is it possible that my <br>iron is too hot, the iron settings is before steam. What do you suggest? <br> thank you!|</p>
