PRODUCTION OF LITHOGRAPHY APPLICATION HIGHLY PRECISE MICRO PARTS AND DIE DEVICE THEREFOR

PROBLEM TO BE SOLVED: To reduce the number of steps of the production process for producing a micro part items by applying a secondary electroplating on a plastic die and mass-producing a highly dense micro parts inside a punching press die. SOLUTION: A mask 22 required for producing a product produced with a punching press die is produced corresponding to its shape. After then, a photoresist 23 is arranged on a substrate 24, and the photoresist 23 is irradiated with an X-ray or an UV rays 21. The photoresist 23 after radiating the beam is developed and one of required plastic die 25 is obtained. A plating metal 26 is applied is electroplating inside the plastic die 25, the plastic die 25 is removed, the micro part items production die of the punching press die is obtained, and the plastic dies are produced by using the obtd. die. By applying a secondary electroplating on the die, the highly dense micro part items inside the punching press die is mass-produced. Therefore, the mass production of the micro part items having high precision and high density is materialized.
