Problems solved by technology

The squeegee will have a certain pressure on the stencil during printing, and the stencil needs to have a certain tension. After the squeegee is scraped, it can rebound well to separate from the circuit board, so that the solder paste that has been printed on the pad will not stick to it. The effect of desoldering paste on the template is poor, resulting in poor printing quality, so the tension requirement for the template is very high. Although the template used for printing has a certain tension on the template attached to the screen after the stretching process, it is still common. There is a problem that the tension is not large enough, so it is necessary to propose a device and its use method to increase the tension of the formwork

Abstract

The invention discloses a reinforcing apparatus for improving mesh stretching tension. The reinforcing apparatus comprises a screen frame and two sets of reinforcing devices, wherein the screen frame is a hollow frame structure composed of two groups of opposite sides and has through holes penetrating the inner and outer sides of the opposite sides, each set of the reinforcing devices comprises a screw mechanism, a cushion block and a gasket, the screw mechanism comprises a threaded screw and a threaded nut, one end of the screw is fixed through the through hole in one of the opposite sides, and the other end of the screw is connected with the nut through the through hole in the other opposite sides. The nuts are span to compact the opposite sides so as to allow the screen frame to have inward deformation, so after the reinforcing apparatus is dismounted, secondary mesh stretching of a silk screen is realized, and the problem of poor solder paste removal capability due to unsmooth rebounding of a template caused by insufficient silk screen tension is overcome. The invention further provides a corresponding application method.

Description

technical field [0001] The invention relates to a reinforcing device for increasing the tension of a stretched net and a method for using the same, belonging to the field of SMT template manufacturing. Background technique [0002] Surface Mounted Technology (SMT), compared with traditional plug-in components, has outstanding advantages such as light weight, small size, and high reliability. It is currently the most popular technology and process in electronic assembly technology. The template for SMT printing is a very important mold in the SMT assembly process, and the printed solder paste is printed on the corresponding pad through the opening on the SMT template. When printing, use a scraper to scrape the solder paste from one end of the template to the other end of the template, and the scraper, template, and circuit board are in linear contact during the entire printing process. The squeegee will have a certain pressure on the stencil during printing, and the stenci...
