video Toner Transfer Walkthrough
Yet another video showing the toner transfer and etching of a pcb. But this one is my way and might have a couple unexpected twists. So turn on your iPod (no soundtrack on this one, sorry) and press play.
Happy Etching!
Notes:
This one spares no detail, in case you are having trouble. It also shows how you can save time, money, and effort, as well as reduce environmental waste, by employing an acid bath in your transfer and post-etch process.
Toner used is third party. Brother toner does not work.
The tank I'm using is not heated, temp of approx 70F.
Etchant is a mix of ferric and cupric chloride.
Laminator is a stock GBC Creative Personal 9" Laminator, which I purchased for <$25.00, including shipping.
The board in the vid is 0.032" thick, single-sided, 1 oz pour. The same methods work for double-sided boards and thicker boards. For the full thickness 0.064" board, I run it through the laminator 8-10 times.

I removed the cover on mine and shoot the larger boards with a 1200W heat gun as they're going through. But the heat gun trick wouldn't work so well with double-sided boards!
Just need to put an 8.2K Ohm resistor in series with the Thermistor.
dimensions are 11"x11"x1"
Seams are solvent welded with acetone.
Mine currently holds about 1.25L with room for probably up to a comfortable 1.6-1.7L.
It IS bloody convenient.
It would be much more convenient to just buy a tank, though. I've done a lot of searching, and one of the best bets for a cheap, leak proof tank approximately this size, seems to be the Tupperware 5L Super Oval. The main downside would be that it requires about 2-3x as much etchant for roughly the same max board size. Dimensions are 10" wide, 2.75" deep, and 11" tall. I've got one on standby, in case my plexi tank doesn't hold up to the test of time. (It's going on 2 weeks now, leak-free, with etchant stored in it 24/7.)
