Problems solved by technology

However, the opening precision of the steel mold made by laser cutting technology cannot meet the requirements, and the quality of the board surface is not high enough, but the electroformed nickel printing screen has become the best among them, which has good flexibility, toughness and Brightness, opening quality and surface appearance are relatively good, and its low stress characteristics greatly broaden its application range. Changing process parameters can control the performance of electroformed products
However, the cost of electroforming nickel is high, the stability of the plating solution is poor, the energy consumption is high, and the income obtained is also limited.

Abstract

The invention discloses an electroforming nickel-ferrum alloy screen with high ferrum content for printing and a preparation method. An opening graphics area according with printing requirements is arranged on the surface of the screen. The nickel-iron alloy contains nickle Ni element and ferrum Fe element, and the mass percents of each element are: Ni:45-60% and Fe: 40-55%. A metal screen with high ferrum content for printing with high hardness, good screen surface brightness and good coating surface quality can be obtained. The nickel-ferrum alloy screen is low cost and saves energy compared to an electroforming nickel metal screen. The nickel-ferrum alloy screen has high opening precision. In addition, the nickel-ferrum alloy screen converts waste impurity ferrum into an alloy constituent, and reduces the solution maintenance cost and the burden of three-waste treatment.

Description

technical field [0001] The invention belongs to the technical field of component preparation, and relates to an electroformed nickel-iron alloy screen, in particular to an electroformed nickel-iron alloy screen for printing with high iron content; at the same time, the invention also relates to the above-mentioned electroformed nickel-iron alloy screen for printing method of preparation. [0002] Background technique [0003] As a manufacturing technology, the advantages of electroforming, such as high replication accuracy, high repeatability and simple process, are unmatched by other manufacturing technologies. Coupled with the manufacturing requirements of various related molds in the SMT industry, electroforming as a This kind of precision manufacturing technology has been highly valued by the printing industry. [0004] Printing stencils are molds used to print solder paste, and steel mesh is generally used at present. However, the opening precision of the steel mold ...
