- SUS304 is a general-purpose steel grade, it is easy to procure materials, and since it causes processing-induced martensitic transformation with processing, it has the merit of high strength and excellent durability, while Ni is a rare metal. It is very effective because it contains a large amount of.
- the metal mask manufacturing method includes laser processing, etching processing, and additive method (electroforming method) depending on the method of forming the opening, and transferability to the substrate is important as well as durability.
- the ease of filling of the solder paste into the opening and the ease of removal of the solder paste from the opening when the metal mask is removed from the substrate after printing the solder paste are important. Further, since the processing end face property greatly affects such filling property and detachment property, it is generally said that a transfer end having a smooth end surface is excellent.
- the additive method is the most excellent for the end face property and dimensional accuracy of the opening.
- the manufacturing cost is high and time is required, and the strength is not improved by rolling, so that the durability is not excellent.
- the etching process although the dimensional accuracy is excellent, since the opening is formed by etching from both sides of the metal mask material, the cross section of the etched portion becomes an irregular shape and the paste is not easily removed. Moreover, the time which provides a resist according to a process pattern is required. In the etching process, since the crystal grain size of the metal mask material greatly affects the etching end face property, the smaller the crystal grain size of the metal mask material, the better the end surface property and the better the removal of the paste.

In order to achieve these effects, Mn and Ni are added in an amount of 0.1% by mass or more and a certain amount or more depending on the Cr content and the C content. However, when the contents of Mn and Ni are increased, too much martensite is generated after the multi-phase treatment, and it is difficult to obtain a two-phase structure. Therefore, the contents of Mn and Ni are each 4.0% by mass or less.

- temper rolling it is preferable to perform temper rolling of 50% or less after the multiphase treatment or after the multiphase treatment because strength can be increased by work hardening by temper rolling. By increasing the strength, durability as a metal mask is improved.
- heat treatment for a short time at 300 ° C. or more and 500 ° C. or less after the multiphase treatment or after the multiphase treatment because the strength can be increased by strain age hardening with solid solution carbon obtained by the heat treatment.
- thermotreat it is more preferable to heat-treat at a temperature of 300 ° C. or more and 500 ° C. or less after a temper rolling of 50% or less because the strength can be further increased by work hardening and age hardening.
- the solidification end temperature (freezing point) is increased, and the solid-liquid coexistence range in the process of solidification from the molten state is reduced, so that the amount of metal that is melted by laser processing can be reduced.
