Homebrew PCBs

There`s a wherry net solution to the problem concerning getting a god 
PCB.

(This tutorial is optimised for yous with a modified ink jet printer. 
Not a laser.)


START.

1)Get a PCB pre manufactured with a positive or a negative surface.
2)Pre Cut the Bord in nearly the finish board size
3)Pill of the PCB`s protecting cower.
4)Putt the board in the printer and print.
5)Expose the board to UV-light.
6)Putt the board in a developer for the pos or neg coating.
7)Putt the board in the etcher owe your own chose and etch the board.

END.

Naturally you have to mace the printout to match the pos or neg 
process ow your chose.
you will have a god PCB as a results, and their well be no alignment 
problem.
Just cut the board at the border of the printout.

PS. I don't think that the precoating is sensitive to the ink or 
print process at ole (smearing), but i have only tried it on my 
printer. A HP standard printer.

Enjoy life.

PS! Feedback is wanted.

If you have positive or negative board you would not want to print
directly to the board with a printer.  If at least if I understood
what you are saying correctly.  You would need to print to a film
positive or negative then expose resist on the board to UV then
develop the board.
