Description
Technical Field
The invention relates to the technical field related to a film covering process of a film protective film, in particular to a method applied to film protection.
Background
The film consists of a medicine film containing photosensitive chemical substances and a base material bearing the medicine film. By means of compact pattern design, lines with resolution of 1-5 microns can be optically drawn on a film, so that the film photoetching technology has wide application in the fields of electronics, automobiles and aerospace.
In the exposure process, the medicine film surface of the film is contacted with the dry film/wet film, and the film is easy to scratch in the long-term use process, so that the precision of a designed circuit is damaged, and the service life of the film is greatly reduced. The protective film with high transmittance to all light and ultraviolet rays is coated on the drug film surface of the film, so that the protective film can effectively protect the film and prolong the service life of the film.
In the film coating process of the film protective film, due to the influence of personnel operation and environmental dust falling, tiny foreign matters are easily coated between the film and the protective film to form fixed foreign matters, the exposure quality is damaged, and even the damage and the open circuit of a designed circuit are caused.
Disclosure of Invention
The present invention is directed to a method for film protection to solve the problems set forth in the background art.
In order to achieve the purpose, the invention provides the following technical scheme, and the method applied to the film protection comprises the following steps:
the method comprises the following steps: cleaning the equipment environment in advance;
step two: opening the FFU and the humidifier of the film covering workshop at least 1h in advance;
step three: an operator performs self dust-free cleaning before entering a film covering workshop;
step four: soaking dust-free cloth with absolute ethyl alcohol, and then carefully wiping the film to clean obvious stains and dust particles on the surface of the film;
step five: transferring the film to a conveying belt of a film laminating machine, pre-coating a layer of protective film on the film by using the film laminating machine, and cleaning foreign matters on the surface of the film again by using stripping force generated in a film tearing mode;
step six: then, paving and covering a PET (polyethylene terephthalate) antistatic film prepared in advance on a film in a full-covering mode to prevent dust falling, and transferring the film to a conveying belt of a film laminating machine; in the laminating process, when the film advances to the laminating roller along with the transmission band, an operator slowly rolls up the PET anti-static protective film on the surface of the film, and the distance between the rolled PET film and the laminating roller is ensured to be 10-15 cm until the laminating is finished.
Preferably, in the step one, the environment cleaning work is to clean the environment of the film covering workshop, the film covering machine table, the workbench and the like for 5S by operators.
Preferably, in the second step, the humidity near the worktable is ensured to be greater than 63% and the humidity near the film covering machine is ensured to be greater than 68% in the film covering process.
Preferably, in the third step, the operator uses a dust stick to carefully remove dust on the surface of the dust-free clothes before entering the film covering workshop, and each body part is wiped for 3 times; subsequently replacing the new glove; covering the tail end and the forearm position of the glove by using a dust sticker, enabling the smooth surface to face outwards, and sealing the joint of the dust sticker and the glove by using an adhesive tape; carefully cleaning the gloves by using pure water and wiping the gloves by using dust-free cloth; entering an air shower, flapping and shaking the body in the air shower process, and rotating for 3-4 circles at 360 degrees; after entering a film covering workshop, using a wall dust sticking to remove dust on the front and back surfaces of the gloves; the operator should avoid as much as possible actions other than the film-coating operation to prevent the cross transfer of foreign matter to the film.
Preferably, in the fifth step, the film protective film used is composed of a high light transmittance PET substrate and an acrylic adhesive, the PET has a thickness of 6 to 12 μm, the transmittance thereof for all light should be > 90%, the transmittance thereof for ultraviolet rays should be > 88%, and the adhesive has a thickness of 2 to 8 μm, the adhesion thereof to PET is >2.2N/25 mm.
Compared with the prior art, the invention has the beneficial effects that:
1. the novel film coating method of the film protective film is provided, so that film coating foreign matters introduced by human operation factors in the film coating process can be effectively reduced;
2. the film and the protective film are effectively prevented from being covered with tiny foreign matters to form fixed foreign matters, so that the foreign matters are prevented from damaging the exposure quality and even causing the damage and the open circuit of a designed circuit.
Detailed Description
The invention improves the traditional method for coating the protective film, and strengthens the control on the cleanness degree of personnel. Foreign matters brought in the hand operation process are avoided to the maximum extent by winding dust stickers on wrists (glove candidates) of operators; by introducing a pre-film-coated protective film mode, the surface of the film is cleaned by utilizing the stripping force in the film tearing process, so that the direct contact of an operator on the film is reduced; and finally, in the process that the film advances along with the conveying belt of the film laminating machine, the PET anti-static film is used for covering the dust falling prevention mode, and the management and control on foreign matters in the film laminating process are effectively realized.
Examples
Cleaning equipment environment in advance, and cleaning the environment of a film covering workshop, a film covering machine table, a workbench and the like for 5S by an operator; opening the FFU and the humidifier of the film covering workshop 2h in advance, and ensuring that the humidity near a workbench is greater than 65% and the humidity near a film covering machine is greater than 70% in the film covering process; before entering a film covering workshop, an operator firstly uses a dust sticking rod to carefully remove dust from the dust-free clothes and replace new gloves; covering the tail end and the forearm position (with the smooth surface facing outwards) of the glove by using a dust sticker, and sealing the joint of the dust sticker and the glove by using an adhesive tape; carefully cleaning the gloves by using pure water and wiping the gloves by using dust-free cloth; entering an air shower, flapping and shaking the body in the air shower process, and rotating for 3-4 circles at 360 degrees; after entering a film covering workshop, using a wall dust sticking to remove dust on the front and back surfaces of the gloves; soaking dust-free cloth with absolute ethyl alcohol, and then carefully wiping the film to clean obvious stains and dust particles on the surface of the film; the film is transferred to a conveying belt of a film laminating machine, a protective film is pre-coated on the film by the film laminating machine, the protective film of the film consists of a 6-micron PET substrate (the total light transmittance is 91.3 percent, the 365nm ultraviolet transmittance is 90.3 percent, and the 420nm ultraviolet transmittance is 91.0 percent) and a 6-micron acrylic adhesive (the adhesion force to PET is 2.5N/25mm), and then foreign matters on the surface of the film are cleaned again by the stripping force generated in a film tearing mode; secondly, paving a PET (polyethylene terephthalate) antistatic film prepared in advance, covering the PET antistatic film on a film to prevent dust falling (full covering), and transferring the PET antistatic film to a conveying belt of a film laminating machine; in the laminating process, when the film advances to the laminating roller along with the transmission band, an operator slowly rolls up the PET anti-static protective film on the surface of the film, and the distance between the rolled PET film and the laminating roller is ensured to be 10-15 cm until the laminating is finished.
