Roll of 30cm x 1m Negative Photosensitive Dry Film PhotoResistive Transfer for PCB Board Feature: Width: 30cm Length: 1M 1.5 mil thickness of dry film can be completely cover a hole of 0.25 inches The dry film can be used in the most ordinary plating solution, no wrinkle, no discoloration It can cut into 10pcs 15cm x 20cm film,and 5pcs 20cm x 30cm film.

Starting from one corner and ending to the cross corner, use your palm to remove all air bubble between film and board, set the iron temperature about 130°C, apply the hot iron down onto the film and PCB, pressing them both flat and putting them under pressure. 3. Expose: Place your negative artwork over the rest protective layer. Use a glass to press the artwork to the board snuggly, then expose to UV light source or under sunlight,the source of light should be at least 8" away from the artwork. The best exposure time is depends, but you can easy to recognize it: the color of film is changing from light blue to dark blue. 4. Develop: Remember: you need NEGATIVE film developer, Remove the rest protective layer on the film, now only resist left on the board, develop board in developer solution that mixed by 1g developer powder with 100g(or 100ml) water (~1% by weight). After 3 minutes take board out of developer and hold under running water to check,you can always place it back in the developer if needs more time.
