Hey all, I finally got myself a hold of some supplies. I decided to go with a simple resealable container and some Ferric chloride. Now the stuff I got was solid, they didn't have any premixed... for a bag of the stuff (it looked like yellow beads), it said it could mix 1L. I figured this was more than I needed, so I just used 1 Cup (~250ml), and consequently, a quarter of the bag. I cut myself a really small peace of PCB material, drew some lines on it (both with an etching marker that I purchased, and a 'Sharpie' - the etching marker was really thick, so I decided to try both since the Sharpie was thinner). I have been waiting 1.5 hours now, and I can't really tell if it is done, but it doesn't seem to be. I take it out periodically, and dry it off. I then check continuity in the regions OUTSIDE the tracks, and it is still conducting. Shouldn't the etchant eat away everything but the tracks? When I rub the marker off, there lies a nice shiny copper track... but it's still basically one copper plate, not individual tracks. Am I doing something wrong (maybe not enough FeCl, long enough period...)? Thank you, Jai Ps: I mixed with hot water, just to speed things up. ---------------------------------------- This mail sent through www.mywaterloo.ca -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
