Multilayer Ceramic Electrode Layout to Prevent Pressing Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing multilayer ceramic electronic components face challenges in preventing deformation of internal electrode patterns and promoting steps due to printing misalignment, leading to suboptimal component quality.
Innovation Solution
A method involving the formation of internal electrode patterns on ceramic green sheets, application of ceramic paste that overlaps the end portions of these patterns, and strategic cutting at a stepped region between adjacent electrodes, which helps in reducing deformation and step promotion during the pressing process.

Engineering Contradiction Analysis
1Strength
If ceramic green sheets are pressed to densify the structure, then component strength is improved, but internal electrode patterns may deform under pressure
Solution Approach 1:
The patent applies ceramic paste to stepped regions before stacking and pressing the green sheets. This preliminary action ensures that the stepped regions are pre-filled and smoothed, providing a cushioning effect during pressing that prevents deformation of internal electrode patterns while still allowing sufficient pressure to densify the overall structure and improve component strength.

AI summary
A method for manufacturing a multilayer ceramic electronic component includes preparing a ceramic green sheet, forming a plurality of internal electrode patterns on a main surface of the ceramic green sheet, applying a ceramic paste above the main surface of the ceramic green sheet, stacking a plurality of the ceramic green sheets, pressing the plurality of stacked ceramic green sheets, and cutting the plurality of pressed ceramic green sheets. The ceramic paste at least partially overlaps end portions of the internal electrode patterns, and a stepped region is provided on the ceramic green sheet. When cutting the ceramic green sheets in a first direction, the cutting is performed at a position of the stepped region between two of the internal electrode patterns adjacent to each other in a second direction.
