I would like manufacture a very simple one layer board to learn how a PCB is manufactured. I prepared the layout of the circuit on Eagle Cad, and am planning to use acid etching method: use iron to transfer the toner to the copper board. I already bought the following items:
- Acid: sodium persulfate
- Etching paper: Film paper (http://www.farnell.com/datasheets/1640461.pdf)
- Board material: FR4 Epoxy Fibreglass (http://www.farnell.com/datasheets/52206.pdf)
I bought these items some months ago, I also prefer to buy stuff from Farnell or ELFA as they are convenient for me for some matters and I don't have local stores that I can shop such equipments.
As I search more about how to implement the etching method, I notice that the etching paper(film) that I have is for UV etching method. But I still wonder if I can use it on my production (iron toner transfer, acid etching, ... and it is the only etching paper available on Farnell)? If it is not the case, I see many paper suggestion (Glossy, Carbon 20, Bond) that puzzles me what to use, some even suggest to use magazine papers.
The second question, "photo resist" is printed on the board material (above) that I have. One side of the board is copper coated. I wonder if I can still use that board on my production process? If it is not the case, what material do I need to use, I see many materials like FR2, FR4, epoxy resin, FR-3, CEM-1/2/3/4, G-10....?
Would you suggest any other materials/equipment I should have apart from etching tray, sand paper, plastic glove, iron, hand-driller?
