Abstract
The invention discloses a ferro-nickel alloy screen plate and a preparation method thereof. The surface of the screen plate is provided with an open graph region meeting the printing requirement; the ferro-nickel alloy contains 35-37% of Ni element and 63-65% of Fe element in percent by mass. By adopting an electroforming method, a ferro-nickel alloy screen plate with higher iron content is obtained, and performances of the ferro-nickel alloy screen plate are closer to those of an electroforming nickel printing screen plate; and by adopting the preparation method, manufacturing cost of the screen plate can be effectively reduced, and the wall of an open pore of the manufactured screen plate is smooth, so that the printing requirement is met well; besides, the ferro-nickel alloy screen plate has high uniformity, and qualities of the surface of the screen plate and the open pore are good.
Description
technical field [0001] The invention belongs to the technical field of high-hardness and high-precision component preparation, and relates to an electroformed nickel-iron alloy stencil, in particular to an electroformed nickel-iron alloy stencil for printing with high iron content; at the same time, the invention also relates to the above-mentioned printing Preparation method of electroformed nickel-iron alloy stencil. 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 accurately tin the pads that need to be tinned at one time is ...
