The most important thing is to have good print , done with good quality toner.
Here we use some dangerous chemicals so be very careful if you going to do this at home.
Please check following video for details, and I will show you also few steps in following points.
First you must have good print, done with good quality toner.
Then we put prepared PCB in plastic box.
For etching we use HCL and Hydrogen peroxide.We pour in HCL just enough to cover PCB, then we add a little of peroxide.
We immediately see how reactions with copper occur.
Here we see bubbles in the reaction of acid with copper.
After few minutes we can see full reaction .
After etching is done, we rinse pcb with water.
Use a steel sponge to remove any toner residue.
The PCB looks almost perfect.
It is very important to have a well-done print at the very beginning, with quality toner.
