Ceramic Electronic Component Layering for Mark Sinterability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The uneven scattering of celsian crystals within ceramic electronic components leads to varying densities among element bodies, affecting the sinterability and visibility of identification marks, which are formed by firing with the element body, resulting in inconsistent performance.
Innovation Solution
Incorporating a second layer with a lower proportion of a specific compound, such as celsian, between the identification mark and a first layer containing barium and silicon, maintains high sinterability and visibility of the identification mark by controlling celsian density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If celsian is added to improve mechanical properties and electrical insulation, then strength and reliability are improved, but sinterability of the identification mark decreases
Solution Approach 1:
The patent applies local quality by creating a second layer with lower celsian content specifically at the interface between the identification mark and the first layer. This localized modification allows the bulk material to maintain high celsian content for mechanical strength while the specific region near the identification mark has reduced celsian to improve sinterability and visibility.
2Productivity
If celsian density varies in different element bodies, then manufacturing efficiency is maintained, but identification mark visibility and sinterability become inconsistent
Solution Approach 1:
The patent segments the element body into multiple layers with different celsian contents. The first layer contains high celsian density for mechanical properties, while the second layer contains lower celsian density to ensure consistent identification mark sinterability across all element bodies, regardless of the overall celsian distribution in the wafer.
Solution Approach 2:
By creating a specific second layer with controlled lower celsian content at the identification mark interface, the patent ensures that this critical region has consistent properties across all element bodies, making identification mark quality independent of variations in overall celsian distribution.
