Glass Electronic Component Side Coating for Optical Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent glass electronic components are difficult to detect using laser sensors or cameras due to their transparency, which complicates recognition and appearance inspection, and they also face issues with mechanical strength and stray capacitance.
Innovation Solution
The electronic component features a glass substrate with a colored insulation layer on its side surfaces and protrusions, along with through-conductors, which enhances detectability and mechanical strength, while reducing stray capacitance by strategically placing the colored insulation layer and protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transparent glass is used for the electronic component, then the insulative and chemical stability properties are improved, but the detectability by laser sensor or camera deteriorates
Solution Approach 1:
The patent applies a colored insulation layer on the side surface of the glass substrate. This colored layer changes the optical properties of the otherwise transparent glass, making it detectable by laser sensors and cameras while maintaining the underlying glass's insulative and chemically stable properties.
2Reliability
If transparent glass is used for the electronic component, then the insulative properties are improved, but the mechanical strength deteriorates
Solution Approach 1:
The patent creates a composite structure by combining the glass substrate with a colored insulation layer. This composite design allows the glass to provide insulative properties while the additional layer contributes to mechanical strength and durability.
3Difficulty of detecting and measuring
If the side surface of the glass substrate is exposed, then the detectability is improved, but the mechanical strength against external force deteriorates
Solution Approach 1:
The colored insulation layer is applied to the side surface to provide both detectability and mechanical protection. The layer's coloration enables detection while its physical presence reinforces the glass against external forces.
Solution Approach 2:
The combination of glass substrate and colored insulation layer creates a composite structure where the insulation layer serves dual functions: optical detection and mechanical reinforcement of the exposed side surface.
4Ease of manufacture
If no colored insulation layer is provided, then the manufacturing process is simplified, but the detectability by detector deteriorates
Solution Approach 1:
The colored insulation layer is integrated into the manufacturing process as a necessary functional element. While it adds a step to the process, it enables detection functionality that would otherwise be impossible with transparent glass alone.

AI summary
An electronic component includes a glass substrate having a main body and a protrusion, the main body including top and bottom surfaces, and a first side surface connecting the bottom and top surfaces to each other, the first side surface of the main body being provided with the protrusion; a colored insulation layer on at least the first side surface of the main body; and a through-conductor within the main body and extending through the top surface and the bottom surface. The protrusion extends in a first direction that is orthogonal to the top surface, as viewed from a direction orthogonal to the first side surface. As viewed from the direction orthogonal to the first side surface, at least a portion of the colored insulation layer extends in the first direction and is adjacent to the protrusion in a second direction that is orthogonal to the first direction.
