Abstract

The invention discloses an electroforming nickel-ferrum alloy screen 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 the elements are: Ni:38-44% and Fe: 56-62%. The performances of the obtained nickel-ferrum alloy screen with higher ferrum content for printing through an electroforming method are close to performances of an electroforming nickel screen for printing. The preparation cost can be reduced effectively. The prepared screen opening has a smooth hole wall, which satisfies the printing requirements well. In addition, the screen is advantaged by high uniformity, good screen surface quality and good opening quality.

Description

technical field [0001] The invention belongs to the technical field of co-deposition of electroforming alloys, and relates to an electroformed nickel-iron alloy stencil, in particular to an electroformed nickel-iron alloy stencil for printing with high iron content, and the iron content is similar to that of an invar alloy plate; meanwhile, the present invention The invention also relates to a method for preparing the electroformed nickel-iron alloy screen plate for printing. Background technique [0002] With the rapid development of my country's electronics industry, stencil printing technology has also been applied in the electronics manufacturing industry, and SMT printing is a typical example. In the manufacturing process of electronic products, soldering electronic components and PCB needs to put tin on the PCB first, and there are hundreds of pads on the PCB that need to be tinned. The position of each pad corresponds to the electronic component. The best way to accu...
