i just bought a ferric chloride powder for my etching. Can anyone show me the proper instruction on the application... how much water is needed for mixing and is there any ratio? It's easy enough, draw your design in negative on your work-piece with your chosen masking material (just about anything from enamel paints to some heavy felt tipped pens will work) then just mix some of the powder with water, about a table spoon full in a pint of water should be enough but you can play with the proportions. Immerse the piece in the liquid with the mask material in place and leave. If you heat the liquid it'll work faster. It's the process used to make printed circuit boards at home by hobbyists so it'll be detailed in most electronic hobby manuals. -- William Black Free men have open minds If you want loyalty, buy a dog... |
