The Saltwater etch process

Step 20 The etched board

You see here the board after etching and cleaning. The paint can prove somewhat difficult to remove. You will need to use an appropriate solvent for the etch resist you have used.

Or you can use the abrasive pad to rub the paint off.

It might also be possible to leave the paint on the board, and remove it only where it is needed to solder. In this case it might produce toxic fumes while being soldered.

You will notice that all the traces are joined together, these will have to be cut apart before the board can be tested.
