[0060] Since a plasticizing step is included in the offset printing method of manufacturing a filter for shielding electromagnetic interference according to an embodiment of the present invention, a resin substrate having poor heat resistance cannot be used in the offset printing method. Therefore, the glass substrate 20 is used as a substitute for the resin substrate. Since those skilled in the art can understand other contents of the offset printing method, details thereof will not be repeated here.
[0061] When preparing a filter for shielding electromagnetic interference using photolithography instead of offset printing, a copper film is first adhered to a resin film. Then, a dried resist film is laminated on the copper film and subjected to an exposure step, a development step, an etching step, and a lift-off step to form a pattern. Therefore, the preparation steps are complicated, and the yield is not good.
[0062] In addition, when a filter for shielding electromagn...
