Abstract
The utility model provides a sawtooth edge ceramic screen printing plate for ceramic slurry printing in MLCC wet process, which comprises a screen printing plate body; the screen printing plate body is made of stainless steel mesh cloth, and a plurality of sawteeth are uniformly arranged on the edge of the screen printing plate body. The method combines the characteristics of a full-automatic four-station wet printing process, adopts a special sawtooth pattern design process, can solve the problem of thick edge printing of a product to a certain extent, avoids the problems that an electrode screen plate is suspended when an internal electrode is printed, the electrode pattern is incomplete, improves the consistency of product capacity, and is suitable for printing and manufacturing of ceramic layers in the full-automatic silk-screen printing of the MLCC wet process.
Description
Technical Field
The utility model relates to a sawtooth edge ceramic half tone of ceramic thick liquid printing usefulness in MLCC wet process.
Background
The wet process is used as one of the process methods for manufacturing the MLCC, the advantages of drying and printing alternative complementary printing are utilized, the defects of internal air hole defects, sintering delamination cracking and the like of the product can be reduced, the method is particularly suitable for a new generation of high-end chip type special high-voltage MLCC, the product has the characteristics of high voltage resistance, low loss, low equivalent series resistance and the like, and the method is widely used for radio frequency/microwave circuits of various direct current high-voltage circuits, missile systems, airplane radars, navigation systems and the like.
The MLCC green body printing is a key link in a wet process, a certain thick edge is gradually generated at the peripheral edge of a green body in the green body printing process, the thickness of the thick edge is gradually increased along with the increase of the printing thickness, and as a result, the graph is incomplete when an electrode is printed by an electrode screen printing plate, and the capacity consistency of a product and the reliability of the product are finally influenced. The problem can be solved by starting from the aspects of the characteristics of the ceramic paste, the printing parameters, the drying process, the ceramic screen printing plate manufacturing and the like.
The thickness of the thick edge of the ceramic screen printing plate is mainly reduced from the perspective of ceramic screen printing plate manufacturing. When the conventional ceramic screen printing plate is used for printing a ceramic green body, a thick step structure exists at the joint of an emulsion of the ceramic screen printing plate and a steel wire mesh, so that pressure difference exists when a scraper passes through, ink quantity at the edge part of a graph is uneven, the compactness of a finally formed ceramic layer is different, and certain edge thickness is increased to a certain extent.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a sawtooth edge ceramic screen printing plate for ceramic slurry printing in MLCC wet process.
The utility model discloses a following technical scheme can realize.
The utility model provides a sawtooth edge ceramic screen printing plate for ceramic slurry printing in MLCC wet process, which comprises a screen printing plate body; the screen printing plate body is made of stainless steel mesh cloth, and a plurality of sawteeth are uniformly arranged on the edge of the screen printing plate body.
And 22.5-75-degree chamfers are machined at the tops of the saw teeth.
The arc size of the sawtooth is 0.3-0.4 mm.
