1. a manufacture method for metallic filter, it comprises following operation:

  • Stacked operation, this operation is stacked photosensitive polymer combination and form photosensitive polymer combination layer on copper base;

    Exposure process, this operation is that the established part of described photosensitive polymer combination layer is irradiated to active ray, makes the part generation photocuring being exposed and forms the cured article of photosensitive polymer combination;

    Developing procedure, this operation is that the part beyond the cured article of the described photosensitive polymer combination in described photosensitive polymer combination layer is removed by developing, and forms the corrosion-resisting pattern being made up of the cured article of described photosensitive polymer combination on described copper base;

    Plating process, this operation is that the described copper base that has formed corrosion-resisting pattern is carried out metal deposition and forms coating;

    Dissolution process, this operation is to remove described copper base by chemical dissolution, thereby obtains the works being made up of the cured article of described coating and described photosensitive polymer combination;

    AndStripping process, this operation is from described works, to remove the cured article of described photosensitive polymer combination, thereby obtains described coating,Wherein, described coating is metallic filter.
