Problems solved by technology

The photosensitive resin is in a semi-dry state, and the photosensitive resin used in the photosensitive dry film in the prior art will emit an extremely unpleasant odor, which has a relatively large impact on the working environment, thereby seriously affecting the health of employees; at the same time, this odor Odor is also an unfavorable factor causing air pollution
At present, some manufacturers of photosensitive dry film also try to add some substances similar to industrial flavors in the photosensitive resin composition, but the effect is not good, and the odor of photosensitive dry film that plagues the industry has not been solved.

Abstract

The invention discloses a photosensitive dry film which sequentially comprises a PET (Polyethylene Terephthalate) support film layer, a photosensitive resin layer and a PE (Polyethylene) protective film layer, wherein the photosensitive resin layer mainly comprises the following materials in parts by weight: 60-70 parts of alkali-soluble resin, 15-25 parts of a polymerizability compound with at least one ethylene unsaturated base, 1-2 parts of a photopolymerization initiator and 0.01-0.1 parts of deodorant. The deodorant can exert a solubilizing function on a low polymer in the photosensitive resin layer, and can inhibit volatilization of the low polymer, so that the photosensitive dry film can inhibit or eliminate the original distinctive odor in the photosensitive resin layer. After the deodorant is added, the performances, such as photosensitiveness, mechanical strength and resolving power of the photosensitive dry film are not affected.

Description

technical field [0001] The invention relates to a photosensitive dry film, in particular to a photosensitive dry film with suppressed or eliminated special odor; the invention also relates to a detection method of the photosensitive dry film. Background technique [0002] With the improvement of people's health awareness, more and more attention is paid to the requirements of the working environment. As we all know, in the production process of printed circuit boards, a photosensitive dry film is used to form a circuit pattern, and the photosensitive dry film includes a supporting base film, a photosensitive resin and a protective film. The photosensitive resin is in a semi-dry state, and the photosensitive resin used in the photosensitive dry film in the prior art will emit an extremely unpleasant odor, which has a relatively large impact on the working environment, thereby seriously affecting the health of employees; at the same time, this odor Odor is also an unfavorable...
