5G communication filter dielectric ceramic piece semi-finished product and forming method thereof

Abstract

The invention relates to a 5G communication filter dielectric ceramic piece semi-finished product and a forming method thereof. The 5G communication filter dielectric ceramic piece semi-finished product comprises a main body, wherein the main body is provided with a cross-shaped through hole and a linear through hole, the cross-shaped through hole is located in the edge of the main body, a first blind hole is formed in the front face of the main body, a second blind hole is formed in the back face of the main body, the main body is provided with an extension part, the extension part is locatedon the side, which is close to the cross-shaped through hole, of the main body, and the extension part is of an arc-shaped structure. The forming method comprises the steps of designing a mold, manufacturing a feed, carrying out injection molding, degreasing with a solvent, carrying out thermal degreasing and sintering. The extension part is added to the thin wall of the main body, one-time injection molding can be achieved, the injection molding defect of the 5G communication filter dielectric ceramic piece is effectively overcome, the product quality is guaranteed, and the yield is increased. In addition, 5G communication filter dielectric ceramic piece semi-finished product is simple in machining process, and suitable for batch production.

Description

technical field [0001] The invention relates to the technical field of ceramic injection molding, in particular to a semi-finished product of a 5G communication filter dielectric ceramic part and a molding method thereof. Background technique [0002] The 5G communication filter dielectric ceramic part is the core component of 5G microwave communication. Its structure is complex and its requirements are high. The existing manufacturing method is: use powder pressing to make a semi-finished product, and then make it into a finished product through a series of treatments such as silver plating. . Due to the difficulty in controlling the size in the thickness direction of powder compaction and the uneven density of the compacted blank, product deformation is likely to occur after sintering. The above shortcomings must be compensated by mechanical processing after sintering, so the production cost is high and the efficiency is low. Not only that, because this product has many h...

AI Technical Summary

Problems solved by technology

Due to the difficulty in controlling the size in the thickness direction of powder compaction, and the density of the compacted blank is not uniform, it is easy to produce deformation of the product after sintering. The above shortcomings must be compensated by mechanical processing after sintering, so the production cost is high and the efficiency is low.

Not only that, because this product has many holes and there are holes on both sides, the product is very prone to cracks and potential micro-cracks during the pressing molding process, which will affect the product yield and increase the cost
