You will easily see your circuit diagram appeared on the board. 7, developing and tear the protective film on the front panel, into the developer (developer according 1:100,10 gram Total 1L of water) to be used when developing a ttle harder stick cotton wipe board. 8, etching, this goes without saying (ferric chloride etchant environmental For protection, hydrochloric acid + hydrogen peroxide, etc.) is recommended environmental etching shop, fast, clean, no odor. 9, after a good CCL etching, stripping, from film watered by 1:60 or 70, the board bubble ke a few minutes, 10, after the completion of the board, very pretty good, most dense ne spacing is 0.1MM, width 0.1MM, 0.1MM nes do know though is very easy to do, but do 0.1 nes and 0.1 ne spacing dry film can easily do it.
