Description:Photographic film, also known as film, is used to make PCB board, stick it on top of the PCB, it will become a sensitive circuit board. The film is resistant to most of the etching solution, the PH value can be resistant to most alkaline etching solution between PH8.0-8.5. 1.5 mil film can fully cover a 0.25 inches thickness hole. The film is available in most common use of the plating bath, no wrinkles, no color. Length: 1mPackage Includes:1 Piece Photosensitive FilmNote:Operating steps: 1.grinding CCL, this simple, using the finest polished clean water frosted paper on the 2.removing film, photographic film is sandwiched between two layers of film, the first side can make use of transparent tape tear torn, try a few on the 3, and then foil, copper clad laminates can look a little cleaner, pasted, try not to have bubbles. 4, good paste membrane used presses, not too hot, about 100 degrees from the fixing. 5, the printed circuit board film, suggestion is to use film, the fine could reach the highest degree of accuracy if you did not ask for the paper to print it with sulfuric . 6, the printed circuit on the photographic (Note: film is negative, so to highlight the print, which we usually use photographic opposite) with ordinary energy-saving lamps 10 or so, if there is exposure Machine 1 minutes on the line, the sun not tried, it should be - , the exposure process Obviously, since the photosensitive film will change color when exposed to light, the light becomes dark blue. 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 of water) to be used when developing a little harder stick cotton wipe board. 8, etching, this goes without saying (ferric etchant environmental For protection, hydrochloric + , 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 like a few minutes, 10, after the completion of the board, very pretty good, most dense line spacing is 0.1MM, width 0.1MM, 0.1MM lines do know though is very easy to do, but do 0.1 lines and 0.1 line spacing film can easily do it.
