Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] A specific embodiment of the present invention provides a method for processing thick electrodes (internal electrodes with greater thickness) in the process of manufacturing laminated components, including the following three steps:

[0028] 1) Electrode pattern production: Cut out the internal electrode pattern through-holes on the first green ceramic sheet; this step can be cut with a laser drilling machine. When cutting out the internal electrode pattern through-holes, the subsequent internal electrode printing is also cut The required alignment mark;

[0029] 2) Lamination: taking the uncut second green ceramic sheet and laminating it with the first green ceramic sheet under a predetermined pressure to obtain a laminate with internal electrode pattern grooves;

[0030] 3) Internal electrode printing: use conductive paste to carry ou...

Abstract

The invention discloses a laminated element and a producing method thereof. The producing method comprises a step of producing an inner electrode. A method for producing the inner electrode comprisesthe following steps: 1) producing electrode patterns, namely cutting inner electrode pattern through holes in a first crude ceramic piece; 2) performing lamination, namely laminating a second uncut crude ceramic piece with the first crude ceramic piece under preset pressure so as to obtain a laminated body with inner electrode pattern grooves; 3) performing inner electrode printing, namely performing counterpoint printing on the inner electrode pattern grooves in the laminated body by using conductive slurry, thereby printing the inner electrode, wherein the inner electrode pattern grooves arefilled with the conductive slurry at least. The laminated element is provided with the inner electrode produced through the steps, and the thickness is 20-100 [mu]m.

Description

technical field [0001] The invention relates to a laminated component and a manufacturing method thereof. Background technique [0002] With the development of the electronics industry, the industry has more stringent requirements on the electrical and reliability performance of stacked components such as radio frequency devices, and thick electrode technology can greatly improve product performance and reduce losses, as a way to achieve high-performance components The preferred solution has always attracted much attention. In the traditional manufacturing process of laminated components, limited by the printing conditions, the thickness of the produced internal electrodes is basically about 10 μm, and the maximum does not exceed 20 μm; and the thicker the electrode thickness, the poorer the shape retention in the electrode width, reducing the production accuracy; even if a thick electrode is produced, there are risks such as tearing or bubbling during the lamination proces...
