Description

Main composite is something called Ammonium persulfate (or sodium persulfate/peroxydisulfate), with 5% salt or anhydrous cupric sulfate, not fully sure about it.

  • No any bad smells that may have from Hydrogen Peroxide H2O2 and ferric trichloride
  • The liquid will be slightly blue and almost transparent, a good lucking
  • The etching process is fully under observing, you can fully control the timing and precision.
  • There will no any dirty spot during cleaning.
  • Week acid, no smell, high safety for prototyping!
  • Easy to deal with the scrap.
  • Mix with 1:4 powder: water ratio, you can etch 10*15cm single sided board 10 – 15 pcs
  • One pack is 200g,

1. Making solution:

Mix one bag of etching powder with 0.8l of water in plastic container, Use wood, glass or plastic sticker stirring it until all powder disappeared

2. Etching:

Drop the board into the solution until all bare copper etched off, during this process, you can monitor your PCB very easy due to the solution is clear or semi-clear.

Rinse:

Rinse the circuit board in tap water. Ensure that all of the previous solution is cleaned off the board.

Etching time is 5 to 10 minutes at 45°C

The solution is clear when it is fresh and change to blue after used

The solution will generate Oxygen(O2) when etching, it is good to air.

3. Notice:

Don’t heat the solution over 60°C.

Don’t use same container for developing and etching.
