The etch film use and production steps：The,etch,film,use,and,producti
In the metal etching process, film to film the traditional, its principles are similar and traditional photographic, film film will first need etching pattern through the transfer of light painting way to two identical, or through the transfer of lithography to the two identical glass film. Then the film alignment by artificial alignment mode or machine alignment mode. Then the coated photosensitive ink or paste dry film photoresists steel sheet is arranged on the film, inspiratory after exposure. The steel sheet film black at the exposure is not sensitive, steel plate at the corresponding film white, steel plate of the ink or dry film polymerization. Finally, after developing machine, steel piece is photosensitive ink or dry film is not the developer to melt, but not the photosensitive ink or dry film dissolved removal in the developer, so need etching pattern by exposure from the etch film transferred to the steel sheet. Then the etch film is how to make? See the following etching film production process:
1, confirm the drawing material, thickness, tolerance, there is no special requirements;
2, convert DXF into CAM350 editing typesetting;
3, edit the character, the client code, name, material, thickness, corrosion, test number, project number, the first time out film NO:1 as upper and lower sheets need to specify UP DOWN such as: (NAME:ZL-019 MODEL:M930 AUDIO MATERIAL:C5191 T=0.15 OVER:0.04 AMOUNT:1000PCS GCBH: ZLD-091203-16 NO:1 UP)
4, in the film with Chinese characters marked proofing, production, E proofing;
5, in the film on a test hole convenient measurement in the process of production, aperture hole size with product line;
6, in the film composition with numbers and letters marked with the number of horizontal vertical;
7, if there are several film modified to indicate several times in small characters.
