Embodiment 2

[0046] Embodiment 2 of the method for producing ceramic sheets for ceramic packaging bases in the present invention, the difference between this embodiment and Embodiment 1 is that in this embodiment, only one fixing block is provided, and the fixing block is a stepped fixing block , the fixed block is provided with four cutting reference planes, which are respectively used for cutting and trimming the two sides opposite in the length direction and the two sides opposite in the width direction. When in use, press the ceramic green sheet on the side of the fixed block with fingers Then cut the corresponding sides according to the cutting datum.

Embodiment 3

[0047] Embodiment 3 of the method for producing a ceramic sheet for a ceramic package base in the present invention, the difference between this embodiment and Embodiment 1 is that in this embodiment, when cutting and trimming the ceramic green sheet, the ceramic green sheet The slices are squared, and the corresponding sides are cut and trimmed with a cutter.

Embodiment 4

[0048] Embodiment 4 of the method for producing ceramic sheets for ceramic packaging bases in the present invention, the difference between this embodiment and Embodiment 1 is that in this embodiment, when making ceramic green sheets, the ceramic green sheets are directly cut by a cutter. The green sheet is cut to obtain ceramic green sheets.

Abstract

The invention relates to a production method of ceramic chips for a ceramic packaging base. The method comprises the following steps of: 1, manufacturing a ceramic green body plate, and dividing the plate-shaped ceramic green body plate into a plurality of ceramic chip green bodies; 2, cutting and trimming process edges of the ceramic chip green bodies; and 3, sintering and hardening the ceramic chip green bodies trimmed in the step 2 to obtain the ceramic chips. In the production process, the ceramic chip green bodies are produced firstly, and the process edges of the ceramic chip green bodies are cut and trimmed based on the characteristic that the hardness of the ceramic chip green bodies is relatively low, so that the size of the produced ceramic chips can conveniently meet the precision requirement.

Description

technical field [0001] The invention relates to a method for producing a ceramic sheet for a ceramic package base. Background technique [0002] The ceramic package base will use ceramic sheets. At present, the production method of such ceramic sheets is: to produce a large plate-shaped ceramic green body, and press out the upper surface and the lower surface of the large plate-shaped ceramic green body. The indentation separation groove separates each ceramic sheet through the indentation separation groove. After sintering and hardening, the large plate is bent by applying bending stress to the large plate on both sides of the indentation separation groove through the split device, so that the large plate breaks from the indentation separation groove. , thus forming a monolithic ceramic sheet. [0003] This method is very easy to cause uneven process edges and many burrs on the surface of the ceramic sheet when the indentation separation grooves on the upper and lower surf...
