Iron or hot laminate the film to fix it @ approximately 100 degrees Celsius \u003c\/p\u003e\u003cp\u003e4. Print the PCB film to ensure precision, or use parchment paper instead.\u003c\/p\u003e\u003cp\u003e\u003cb\u003e(You will need a negative design on your transfer film.

The dry film will turn into deep blue from light blue. \u003cb\u003eIf you’re using a UV lamp of 30-40 Watts, 60 seconds should be fine\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003e6. Development: Remove the outer protective film with a piece of cello tape.
