Embodiment

[0063] In order to better confront PCB, and to better transfer the accurate amount of materials to accurate positions, use the power casting process to make electric casting mesh. This process step includes:

[0064] (1) Core mold before processing: remove oil, pickle, and sand spraying core molds to remove the oil stain impurities on the surface, and polish the surface smoothly;

[0065] (2) Film: the film on the surface of the core;

[0066] (3) Exposure: expose the graphic opening area so that the unrepilling area can be removed through the development, leaving the exposure part as the protective film of the subsequent power casting steps;

[0067] (4) Single -sided development: The unprecedented part of the steps in the steps (3) leave the exposure part for the protective film of the subsequent power casting steps;

[0068] (5) Classes: The method of casting the power cast material is used to cast the electrical casting material to the unre exposed area;

[0069] (6) Fading me...

Abstract

The present invention relates to a production method for an electroformed stencil with mark points, including the production of the electroformed stencil and the production of the mark points. The production method is characterized in that the stencil surface area outer the opening pattern area of the electroformed stencil is provided with two round holes diagonally positioned for determining the coordinates of the mark points. The production of the mark points comprises the steps of: placing the fixed electroformed stencil on a cutting base platform; then determining the coordinates of the mark points; adjusting cutting parameters and the vertical height of a laser cutting head to enable a laser focus to fall on the surface of the electroformed stencil; emitting laser light through the laser cutting head to perform cutting at the mark point area on the surface of the electroformed stencil. According to the production method for the electroformed stencil with mark points, the obtained electroformed stencil has good surface quality, no pinholes or pittings, thereby improving printing quality; and the mark points have high positioning accuracy, and relatively high degrees of recognition, improving alignment accuracy of a PCB with the electroformed stencil.

Description

[0001] Technical field [0002] The present invention involves a method of making a grid -based mesh, especially for a production method with a positioning point with a positioning point. [0003] Background technique [0004] As electronic products pursue miniaturization, the perforated plug -in components used in the past have not been reduced; electronic products have more complete functions, and the integrated circuit (IC) used can no longer be perforated components, especially large -scale, high -integrated ICs, and have to use the surface on the surface.Patch components, so the template printing process has developed rapidly in the electronics manufacturing industry, and SMT printing is typical.The production of templates is not only the first step, but also the most important step.The main function of the template is to help the illegal paste deposition, and the accurate amount of materials to the accurate amount of materials to the light board.When printing tin paste, the...
