Solution Overview
Problem
The intaglio printing method for manufacturing electronic components, such as multi-terminal multilayer capacitors, faces challenges in achieving high dimensional accuracy of external electrodes, which is crucial as components miniaturize, while also increasing manufacturing costs due to the need for vacuum equipment in other methods like sputtering and CVD.
Innovation Solution
An intaglio jig with an elastic body featuring recessed portions that include an opening with a protrusion portion on the bottom surface, reducing the volume of conductive paste and enhancing dimensional accuracy by controlling the amount applied and inhibiting paste fluidity, thereby improving the precision of external electrodes without the need for expensive vacuum equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If sputtering method, vapor deposition method, or CVD method is used, then manufacturing precision of external electrodes is improved, but manufacturing cost increases due to vacuum equipment requirements
Solution Approach 1:
The patent uses a disposable intaglio plate with recessed portions instead of expensive vacuum equipment. The intaglio plate is a simple, low-cost component that can be discarded or reused multiple times, replacing the need for costly sputtering, vapor deposition, or CVD systems while achieving comparable dimensional accuracy through controlled paste application in the recessed portions.
Solution Approach 2:
The patent replaces the complex vacuum-based mechanical systems (sputtering, vapor deposition, CVD equipment) with a simple intaglio printing mechanism. The intaglio plate with its recessed portions mechanically controls paste application, substituting high-tech vacuum processes with a straightforward mechanical printing approach that achieves similar precision at lower cost.
2Ease of manufacture
If intaglio printing method is used, then manufacturing cost is reduced, but manufacturing precision of external electrodes deteriorates
Solution Approach 1:
The patent applies local quality by creating recessed portions at specific locations on the intaglio plate where conductive paste is applied. These recessed portions have different depths and geometries tailored to the specific electrode patterns needed, allowing precise control of paste application in critical areas while maintaining the simplicity and low cost of the overall intaglio printing process.
Solution Approach 2:
The patent changes physical parameters of the paste application process by controlling paste viscosity, application pressure, and the geometry of recessed portions. By adjusting these parameters, the intaglio printing method achieves dimensional accuracy comparable to vacuum-based methods while maintaining lower manufacturing costs through the simplicity of the printing mechanism.
3Productivity
If component miniaturization is advanced, then productivity is improved, but manufacturing precision requirement increases for external electrodes
Solution Approach 1:
The patent segments the intaglio plate into multiple recessed portions, each designed for specific electrode applications. This segmentation allows the plate to handle miniaturized components with multiple electrodes by applying paste to each electrode location independently through appropriately sized and positioned recessed portions, maintaining precision even as component size decreases.
Solution Approach 2:
The patent introduces depth as an additional dimension in the intaglio plate design, creating recessed portions that extend below the plate surface. This third dimension (depth) provides precise control over paste application volume and shape, enabling high dimensional accuracy for miniaturized components while maintaining productivity through the printing process.

Function Achieved in This Case
The intaglio jig effectively enhances the dimensional accuracy of external electrodes while reducing manufacturing costs by optimizing the application of conductive paste, ensuring appropriate amounts are applied, thus addressing the limitations of the intaglio printing method and minimizing the need for costly vacuum-based techniques.
Implementation Method 1
an elastic body; when the electronic component body is pressed against the elastic body in which the conductive paste is contained in the recessed portion, the elastic body elastically deforms

AI summary
An intaglio jig for manufacturing an electronic component having an external electrode by applying a conductive paste to an electronic component body includes an elastic body, and a recessed portion that is formed in the elastic body and in which the conductive paste is contained. The recessed portion includes an opening having an opening width that conforms to a width of the external electrode, a bottom surface at a predetermined depth from the opening, and at least one protrusion portion in which a protrusion height locally protruding from the bottom surface is less than the predetermined depth.
