Specification: Item Type: Photosensitive Dry Film Applicable products: PCB board Insulation material: Organic resin Weight: Approx. 50g Size: Approx. 1 * 0.3m / 3.3 * 1.0ft

Package List: 1 * Photosensitive Dry Film

Operating Steps: 1. Uncover the film, the photosensitive film is sandwiched between the two layers of film, first tear off one side, a little difficult to tear, try a few more 2. Then film, the copper plate can be slightly cleaned, flattened, try not to have bubbles 3. After the paste, the iron is slightly heated, not too hot, to fix 4. Print circuit board film, it is recommended to use film, you can achieve the highest fineness, if you do not require precision with tracing paper to print. 5. Exposure, put the printed pattern on the photosensitive plate, use ordinary energy-saving lamps for about 30 minutes, if there is an exposure machine for 1 minute, the sun has not been tried, it should be about 15 minutes, the exposure process is obvious, because the photosensitive The film changes color when exposed, and changes from light to dark blue. You will easily see your circuit diagram appear on the board. 6. Develop, peel off another protective film, put it into the developer (developer is 1:100 water, 10 grams of water, 1 liter of water), and use a cotton swab to wipe the board with a little force during development. 7. Etching, this needless to say etchant water saturated solution 8. After etching, take off the film, take off the film by 1:60 or 70, and soak the board for a few minutes.
