Tin all the parts where a component is going to be soldered. Then solder all the components in place and clean the remaining flux or resin.

What is the mix of acid to hydrogen peroxide, or is it a product off the shelf?

Generally 30% concentrated HCL and 2-3% conc H2O2 in equal quantities will etch the board in 1-2 minutes.

on the anti-adhesive baking paper - is that the same as "Parchment Paper?

Yes, i think so.

FWIW - I just tried a test print on some Reynolds and Reynolds parchment paper with an HP Laser Printer. When R&R claim non stick - they really mean it. You can actually rub the toner off it. I am going to try and iron a pattern on a board - I will be very, very, careful not to smudge the print.

Good job!But I personally prefer etching off the unwanted copper by using a sponge to rub it off,on which a small quantity of the etching solution is poured and by this way you could practically complete hundreds of PCBs with a small bottle of the etching solution.Also you don't have to keep a close eye on the pcb while it is immersed into the solution because using a sponge can give faster results,even within a few seconds.

Excelente manual. Gracias por compartirlo.

You can skip the tinning step if you use a flux pen.
Just apply the liquid flux to the pads, insert the components, and the solder will flow like melted butter.
Nicely done. I love the stripped sample. That's genius. If you want to push this process to it's limits for doing small surface mount stuff you can see how I do it here: http://www.instructables.com/id/Toner-transfer-no-soak-high-quality-double-sided/
