Background
With the rapid development of high technology, laser cutting technology is used in various industries. In the electronic product industry, the original silk screen printing mode has the defects of low precision, poor forming effect, low durability and the like, and in order to meet higher requirements of semiconductors and electronic products, a laser-cut metal sheet hollowed-out printing template is widely adopted and used for template printing in the surface mounting technology. The laser cutting template is formed by focusing a tiny light beam emitted by high-power laser equipment to form a focus, wherein the focus generates high temperature to locally melt the metal template, the metal template is timely cooled by continuous light beams and compressed air, and the metal template is driven by a moving mechanism to make track motion. Its advantages are geometric trapezoidal opening of template, high precision of opening, high flexibility of opening, and high durability. The method has the defects that irregular steel slag (billet burr for short) is adhered to the lower edge of a billet cut after hot melting cutting of the metal plate after laser cutting, high temperature is generated locally when the metal template is cut by laser, the cutting precision can be guaranteed only by timely cooling the metal template, the metal template is oxidized with compressed air when cooled, a thin oxidized black skin (also called oxidized scorching) is formed on the surface of the metal, and the steel slag and the oxidized black skin are not beneficial to printing and demolding or poor printing effect in the printing process of the template.
The present electroformed stencil is a stencil formed by continuously depositing nickel ions, which has the advantages of being beneficial to solder paste rolling and printing demoulding, and being capable of processing metal stencils with different thicknesses, but has the disadvantages of long processing time and high cost.
