Instructions: 1. Uncover the film, the photosensitive film is sandwiched between two layers of film, first tear off one side, it is a bit difficult to tear off, just try a few more times 2. Then paste the film, the copper plate can be cleaned a little, and paste it flat, try not to have bubbles 3. After being pasted, the electric iron will heat up a little, not too hot, and will play a fixed role 4. For printing circuit board film, it is recommended to use film, which can achieve the highest degree of fineness. If there is no requirement for precision, use sulfuric acid paper for printing. 5. Exposure, put the printed pattern on the photosensitive plate, use an ordinary energy-saving lamp for about 30 minutes, if there is an exposure machine, it will do for 1 minute, and I have not tried it under the sun. It should be about 15 minutes, the exposure process is obvious, because the photosensitive film will change color during exposure, from light color to dark blue. You will easily see your circuit diagram appear on the board. 6. For developing, take off another protective film and put it in the developer (the developer should be mixed with water at 1:100, and 10 grams with 1 liter of water). Wipe the test board with a cotton swab while developing. 7. Etching, (ferric chloride, environmentally friendly etchant, hydrochloric acid + , etc.), water saturated solution of etchant 8. After etching, remove the film. Mix the release agent with water at 1:60 or 70, and soak the board for a few minutes. Specification: Material: Plastic Dimension: 30cm*500cm / 11.8*197in Weight: approx. 150g Package List: 1 * Photosensitive Dry Film

PARAMETERS: Material: Plastic; Size: 30cm*5m / 11.8*197in; Weight: about 150 grams. BRIEF STEPS OF USE: 1. Uncover the film and sandwich the photographic film between the two layers of film; 2. Paste the film, clean and paste it evenly; 3. Use an electric soldering iron to heat it slightly; 4. Print circuit board film; 5. Expose; 6. Development; 7. Etching; 8. Demoulding. FEATURES: strong ability to cover holes, high resolution, excellent adhesion to almost all surfaces, and clear images after exposure. FUNCTION: With the help of the dry film, the ordinary copper-clad board can be turned into a photosensitive board, which can completely replace the thermal transfer to make PCB boards; with this dry film, you will make your own photosensitive board. BRIEF INTRODUCTION: Photosensitive film, also known as dry film, is used to make PCB boards. When attached to the PCB, it will become a sensitive circuit board. Suitable for electroplating, hole covering and etching processes.
