Well, I«d like to thanks again to the people that has reply me so well . Ok... Here in my town (out of the United States, in Venezuela) I«ve he ared that somebody is selling something like a Sheet to make PCB design. Yesterday I talked to him and he said: You only got to "Iron" the Sheet (with the Paths made ) on the PCB Board and that«s it. That guy said he Import these "Sheets" from U.S.A, in JDR. I think this is a very good way for me (a student). Somebody know something about that amazing thing...?
