And can be classified into a flat screen printer, a curved screen printer, a rotary screen printer, and the like.

The silk-screen printing is to laminate the protective layer and the interlayer on the cast diaphragm according to the design requirement of the work order, print the inner electrode slurry on the ceramic medium, and laminate the inner electrode slurry together according to a certain dislocation mode to form a whole, namely a bar block.

The inner electrode of the capacitor is used for storing charges, so the flatness, continuity, structure and the like of the inner electrode pattern directly affect the electrical performance and reliability. Therefore, silk-screen printing has very high requirements on process sanitation, precision of production equipment, operating skills of staff and quality awareness. In the aspect of process sanitation, as silk-screen printing is to directly operate the core inner electrode of the capacitor, the requirements on personal sanitation of field operators, large production environment and cleanliness of raw materials are strict, and no dust or impurities exist. Meanwhile, the silk screen printing is to print the inner electrodes and to overlap the media with the inner electrodes, so that the requirement on the precision of the equipment is high, the opposite positions of the upper and lower electrodes cannot be shifted or deflected during printing, and otherwise, the reliability of the capacitor is directly influenced.

The screen printed inner electrodes have a crucial influence on the performance of the chip. The silver weight and the smoothness and flatness of the silver layer are important parameters for measuring the quality of the inner electrode. The uneven thickness and printing of the silver layer can increase the production cost, and when the chip is under the action of an electric field, the concave and convex parts of the internal electrodes can suddenly collect excessive charges to cause the breakdown of the internal electrodes, or the plate resistance is formed to cause the excessive heating of the internal electrodes to cause the burning-out of the internal electrodes. Conversely, if the silver is too heavy or the electrodes are not printed well, the capacitance of the capacitor is directly affected and its loss increases.

The printing machine can conveniently change different printing styles by replacing the template, so that the effect of convenient printing is achieved, when the scraping head scrapes ink glue, two ends of the film are tightened, the film can be spread, when the ink glue is scraped, the pressing template is pushed downwards to push the film, the tension of the film is easily changed, the film cannot be spread after hanging printing, and the printing is inclined;
