💡 What is a common PCB etchant and why is ammonium persulfate popular for copper etching?
It's handy for hobbyists and pros working on copper-clad boards.
- Ammonium persulfate is the active oxidizer that dissolves copper efficiently
- Mix 1 part crystals to 4 parts water to form a ready-to-use etching solution
- ACS reagent grade ensures stable, repeatable etching results
- Etchant is colorless and odorless with minimal by-products
