SUS 304 PLATING METHOD FOR STAINLESS STEEL 304 SHEET COMPRISING CELLULAR PHONE CAMERA MODULE

摘要

The present invention relates to a plating method of a SUS 304 material contained in a mobile phone camera module. The plating method of the SUS 304 material included in the mobile phone camera module according to the present invention includes a pretreatment step (S100) of washing the surface of the SUS 304 material by removing an oxide film, organic foreign substances and oil present on the surface of the SUS 304 material; A photosensitive film coating process (S200) for coating a surface of the pretreated SUS 304 material with a photosensitive film (Dry Film); A master film patterned in a predetermined shape is laminated on the upper surface of the photosensitive film-coated SUS 304 material, and UV is irradiated to the surface of the SUS 304 material for a predetermined time to form the same pattern as the patterning of the master film A UV exposure step (S300) for selectively curing the photosensitive film; A developing step (S400) of dissolving the photosensitive film on which the SUS304 material is not cured with a developing solution; An etching step (S500) of patterning the surface of the SUS 304 material to a predetermined shape by etching the surface of the SUS 304 material using an etching solution; A peeling step (S600) of dissolving and removing the photosensitive film remaining on the surface of the etched SUS 304 material to produce a patterned SUS 304 material having a uniform shape; (Ni) and tin (Sn) on the surface of the SUS 304 material from which the remaining photosensitive film is removed, which is plated with Ni and Sn on the surface of the SUS 304 material from which the remaining photosensitive film has been removed. (S700). According to the above-described structure of the present invention, the characteristics of the plating layer formed of nickel and tin on one side of the SUS 304 material included in the cellular phone camera module are stably and uniformly coated, and the color of the plating layer is not stained, It is excellent in glossiness.
