Embodiment Construction

[0015] The specific steps and methods of the metallization process of the microwave dielectric multi-cavity filter of the present invention are described as follows:

[0016] First, a certain amount of multi-cavity microwave dielectric ceramic substrate (7) that needs surface metallization is placed in the screen (2), and the silver paste bucket (3) containing the silver paste (4) is lifted by the lifting motor (5) , the ceramic matrix (7) in the screen (2) is immersed in the silver paste (4) in the silver paste bucket (3), and the ceramic matrix in the screen (2) is driven by the input shaft of the speed regulating motor (1) (7) Start rotating in the silver paste (4) at a low speed of 2 rpm to 50 rpm for 5 seconds to 100 seconds; immerse the silver paste (4) in the ceramic matrix (7), rotate at a low speed, and then The silver paste barrel (3) is lowered by the lifting motor (5), so that the screen (2) is separated from the silver paste barrel (3), that is, the ceramic substr...

Abstract

A process for metallizing the internal and external surfaces of multi-cavity microwave medium filter includes such steps as putting the multi-cavity microwave medium ceramic body in a screening mesh, using speed-regulatable motor to drive the screening mesh to rotate in Ag slurry at 2-50 rps for 5-100 S and then at 50-500 rps for 100-200 S, baking at 200-500 deg.C, calcining and solidifying in tunnel kiln, and sintering at 700-900 deg.C.

Description

Technical field: [0001] The invention relates to a microwave dielectric multi-cavity filter, in particular to a process for metallizing the outer surface of a microwave dielectric multi-cavity filter product and the inner surface of its cavity. Background technique: [0002] In order to make the surface of non-metallic dielectric material products have conductivity to achieve their electrical properties, usually, the method of secondary processing is used to plate the required metal layer on the surface of non-metallic dielectric materials. The method is generally to first coat the non-metallic dielectric products The surface is pretreated, and then electroplated using the traditional bath plating method to achieve the above purpose. [0003] To sum up, although the currently known surface metallization technologies of non-metallic dielectric materials have their own advantages and disadvantages, none of them break away from the traditional electroplating process category, r...
