I would like to use the photographic process to PCB. Does anybody know
where to find information on that, or maybe some place where to buy a kit?
TIA

Fernando,

This is only one example:

With a little googling you will find more.

It'd help if you said where you are. The World is a big place, and a

There are a number of different 'photographic' processes, and if you want
good accuracy for a small number of boards, in all honesty these days you
would be better off using one of the 'pooling' services and having the
board made. This in many cases costs less than DIY now, with better
quality, and no need to have the chemicals present.
The 'minimum', would normally be to buy resist coated boards (these work
much better than aerosol based systems), developer, etchant, and use
artwork printed in reverse on acetate laser printer film. You also really
need a UV 'light box' (except for very small boards, where the Sun can
sometimes be used), and ideally a bubble etch tank (the PCB, etches much
more accurately, with warm bubbled etchant, than working in a flat tray).
You can for relatively simple boards, skip the use of the photo chemicals
completely in some cases, and use iron the film directly onto a board,
where the ink from the laser printer, will thermal transfer, and provide
an etch resist. There are also special films designed to improve this
process. This is probably the 'simplest' system.
Have a look at:
http://www.awrr.com/pcb.html
Which lists some of the systems, and addresses for many companies doing
stuff.

Best Wishes

Take a look at this site on the Pree-n-peel product
http://www.techniks.com/how_to.htm
I've used the process and it is quite accurate and easy to use. I can't
find my instructions, but I think it says to iron for about 3-4 minutes.
I have found that the easiest for me is to use a hankerchief over the
artwork (make sure it is flat and wrinkle free first) and then iron for
approximately 60-80 seconds on the bottom of the cotton setting. It works
every time for me now.
