Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing laminated electronic components, such as laminated ceramic capacitors, face challenges in achieving high positional precision for inner electrodes due to difficulties in aligning laminated green sheets, leading to inaccuracies in electrode placement.
Innovation Solution
The method involves forming conductive films on green sheets such that their widths are identical or substantially identical, allowing for precise alignment during lamination by ensuring the overlapping portions maintain equal widths, thereby ensuring high positional precision of inner electrodes. This is achieved through gravure printing and careful positioning of green sheets to prevent blurring and maintain consistent dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If green sheets are laminated by alternately displacing them by a certain amount, then the manufacturing process is simplified and does not require multiple types of green sheets, but the alignment precision of laminated green sheets deteriorates, making it difficult to provide inner electrodes with high positional precision
Solution Approach 1:
The patent applies preliminary action by pre-forming conductive films with identical widths on green sheets before lamination. This preliminary preparation ensures that when green sheets are laminated by alternately displacing them, the conductive films automatically align with high positional precision without requiring complex alignment procedures during the lamination process itself.
Solution Approach 2:
The patent changes the parameter of conductive film width to be identical across all green sheets. This parameter change enables the conductive films to align precisely during lamination by alternately displacing green sheets, as the uniform width creates a self-aligning mechanism that maintains high positional precision while simplifying the manufacturing process.
2Ease of manufacture
If the position of green sheets is determined by alternating displacement, then manufacturing is easier, but the positional precision of inner electrodes deteriorates
Solution Approach 1:
The conductive films are pre-formed with identical widths on green sheets before lamination. This preliminary action ensures that when green sheets are laminated by alternately displacing them, the conductive films automatically align with high positional precision, eliminating the need for complex alignment procedures during lamination.
Solution Approach 2:
By changing the parameter of conductive film width to be identical across all green sheets, the patent creates a self-aligning mechanism during lamination. This parameter change enables high positional precision of inner electrodes while maintaining ease of manufacture through simple alternating displacement lamination.

AI summary
In a method of manufacturing a laminated electronic component, in a step of obtaining a laminate, a position of a second green sheet with respect to a first green sheet is determined such that an overall width of a first portion printed on the first green sheet and a second portion printed on the second green sheet becomes substantially equal to a width of the first portion or a width of the second portion.
