As such, I am getting good at making the boards. These three are waiting for some components I should get later this week. I have added everything that I do have, so that they will be quick to finish when the parts arrive. The question is how many of these can I get made before then. Here are the steps I have to perform for each one...
- Cut out the front and back print outs (5 min)
- Polish the blank PCB that has already been cut to size and clean (5 min)
- Iron the front and back patterns to the PCB (15 min)
- Soak in water, scrub to remove paper residue (15 min)
- Etch (30 min)
- Scrub excess toner away (5 min)
- Drill, grind and smooth (20 min)
- Solder components (20 min)
- Clean and dry (5 min)
Total Time: 2 hours (per board)
For the next set of boards, I am going to try using the White Vinegar, Hydrogen Peroxide and Salt solution to etch the boards. The bottle of Ferric Chloride I purchased from Radio Shack some time ago is about depleted. It has taken on a nasty greenish tint, but actually still seems effective at etching. I am just anticipating the move to a "cleaner" etchant because it is cheap and not as toxic.
