Colored Insulation Layers for Circuit Carrier Layer Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circuit carriers with metal substrate layers face challenges in meeting stringent insulation requirements, particularly in the automotive industry, where it is difficult to unambiguously identify and count the number of insulation layers.
Innovation Solution
A circuit carrier design featuring at least two electrical insulation layers with different colors applied directly on top of each other, allowing for unambiguous identification and counting of the insulation layers, even in cross-sectional views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple insulation layers are applied directly one on top of the other to meet insulation requirements, then the insulation capacity is improved, but the ability to unambiguously identify and count the insulation layers deteriorates
Solution Approach 1:
The patent applies different colors to different insulation layers (e.g., first insulation layer in white, second insulation layer in black) to enable unambiguous visual identification and counting of the layers. This color differentiation resolves the detection difficulty while maintaining the required insulation capacity through multiple layers.
2Device complexity
If two insulation layers are applied directly adjacent to each other to save space and meet requirements, then the device complexity is reduced, but the measurement precision of the number of insulation layers deteriorates
Solution Approach 1:
By coloring the insulation layers differently (e.g., white and black), the patent enables precise visual counting and identification of each layer even when they are applied directly adjacent to each other. This maintains structural simplicity while achieving accurate layer verification for quality control.
