Computer modding or a hobby for radio electronics can often require non-standard solutions: for example, the independent manufacture of a printed circuit board capable of performing a highly specialized task and, as a result, not available on the free market. Of course, this is not the easiest task, however, there is nothing that an enthusiast cannot do.
Necessary
- - textolite
- - nitro paint (at worst - nail polish)
- - drill with a diameter of 1 mm.
- - ferric chloride
- - plastic container
- - soldering iron
Instructions
Step 1
Mark up the elements (parts and tracks) of the future board using a pencil.
Step 2
Degrease the surface with acetone and paint the tracks with nitro paint, a special marker or nail polish.
Step 3
Pour the ferric chloride solution into a plastic container and place the future PCB there for 15 minutes (it can be longer if the solution is not fresh).
Step 4
Remove the textolite from the solution, make sure that there is no copper left on it (except for the one hidden under the paint), wipe it off and dry it.
Step 5
Use acetone to remove paint / varnish from the board.
Step 6
Drill holes where you want, solder the parts you want, and use your own PCB.
