●  Chitai electronic protective films are produced in thousand level or hundred level or dust-free workshop in which internationally leading air filtering, distribution and optimization technology are adopted, so that the indoor temperature, cleanness, indoor pressure, air flow speed and air flow distribution, noise vibration and lighting as well as silence control are all in the limit range required for product production. The products produced under this environment are all featured by good softening property and are dust-free and static-free. This provides powerful protection for the manufacturing process of high-grade and precise electronic products.
