Problems solved by technology

[0002] When making ceramic components, it is necessary to print a layer of slurry on the surface of the high-temperature co-fired ceramics after the production is completed. The traditional printing method is screen printing, and the slurry is pressed by a scraper to cover the ceramic sheet. However, when it is necessary to print the paste on the inner wall of the through hole on some ceramic sheets or when it is necessary to fill the through hole on some ceramic sheets with paste, use the traditional screen printing method to cover or fill the hole , the force of the scraper to squeeze the slurry is insufficient, and the hole-filling slurry cannot effectively pass through the screen, resulting in insufficient filling and incomplete coverage of the inner wall. Repeated printing is required to completely cover the inner wall of the through-hole or fill it. , low efficiency, very inconvenient

Embodiment Construction

[0015] Such as figure 1 A screen printing process for high-temperature co-fired ceramics is shown, which includes the following steps: 1. The high-temperature co-fired ceramic green porcelain is integrated and pressed into blocks by an isostatic pressing process to form a suitable green porcelain blank 1, The thickness of the green porcelain blank 1 is 0.1mm-0.5mm, place the green porcelain blank 1 on the table top 2 of the screen printing machine, and connect the first vacuum port 3 on the screen printing machine table 2 with the through hole 4 of the green porcelain blank 1 alignment;

[0016] 2. Turn on the vacuum device (not shown in the figure), use the second vacuum port 5 on the table 2 to absorb the green porcelain blank 1, and transmit the vacuum suction to the through hole 4 of the green porcelain blank 1 through the first vacuum port 3 ;

[0017] 3. Use a screen printing machine to screen-print the green porcelain blank 1, wherein the distance between the screen 6...

Abstract

The invention provides a silk screen printing technology for a high temperature co-fired ceramic. The silk screen printing technology can increase the printing and porefilling efficiency of the innerside walls of through holes. According to the technical scheme, the silk screen printing technology for the high temperature co-fired ceramic is characterized by comprising the following steps that 1,a green ceramic blank is placed on a table surface of a screen printer, and a first vacuum port of the table surface of the screen printer is aligned with through holes of the green ceramic blank; 2,a vacuum pumping device is turned on, a second vacuum port of the table surface is used for adsorbing the green ceramic blank, and the vacuum suction is transmitted to the through holes of the greenceramic blank through the first vacuum port; and 3, the green ceramic blank is subject to silk screen printing through the screen printer.
