Do you know the quick way to make a circuit board?
Chemical methods: By covering the protective layer on a blank CCL, unwitting copper corrosion in corrosive solutions is the method used by most current developers. Cover the protective layer of a variety of methods, mainly the most traditional hand-painted paint method, paste the custom stickers method, film photographic methods and in recent years only developed thermal transfer PCB board method.
Paste stickers: the market has a variety of stickers are made into strips and disc-like, in the blank circuit board according to the need to combine different stickers, sticky can be corroded.
Film photographic: the PCB circuit board through the laser printer to print on the film, blank CCL pre-coated with a layer of photosensitive material (the market has been coated with copper clad sale), in the darkroom environment exposure, development, fixing, cleaning After the corrosion in the solution.
Thermal transfer: through the thermal transfer printer to print directly on the blank circuit board, and then into the corrosive corrosion.
