Glass Electronic Component Sidewall Marking for Optical Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Highly-transparent glass electronic components are difficult to detect using laser sensors or cameras due to their transparency, which poses challenges in recognition and appearance inspection.
Innovation Solution
The electronic component includes a glass substrate with a crystallized portion and a colored insulation layer on its side surface, allowing for easier detection by providing a low-transparency feature that can be recognized by detectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If highly-transparent glass is used for the electronic component, then the insulative and physical stability properties are improved, but the detectability by laser sensors or cameras deteriorates
Solution Approach 1:
A colored insulation layer is provided on the side surface of the glass body. The colored insulation layer has a color different from the glass body, creating a visual contrast that enables detection by cameras and laser sensors while maintaining the transparent glass structure for insulative and stability properties
Solution Approach 2:
The colored insulation layer acts as an intermediary element between the transparent glass body and the detection system. It provides the visual contrast needed for detection without compromising the fundamental properties of the glass material
2Reliability
If highly-transparent glass is used for the electronic component, then the insulative and physical stability properties are improved, but the appearance inspection capability deteriorates
Solution Approach 1:
The colored insulation layer provides visual contrast against the transparent glass body, enabling cameras to detect the presence, position, and orientation of the electronic component for appearance inspection purposes
3Ease of manufacture
If the side surface of the glass body is exposed, then the manufacturing simplicity is improved, but the mechanical strength against external forces deteriorates
Solution Approach 1:
The colored insulation layer is composed of glass powder and binder mixed in specific proportions (glass powder: 90-99 wt%, binder: 1-10 wt%). This composite structure provides both mechanical strength enhancement and color contrast for detection, while being applied directly to the glass body side surface

AI summary
An electronic component includes a glass substrate having a glass body and a protruding crystallized portion, the glass body including a top surface, a bottom surface, and a first side surface connecting the bottom surface and the top surface to each other, and the first side surface having the crystallized portion; a colored insulation layer on the first side surface; and a through-conductor within the glass body and extending through the top surface and the bottom surface. The crystallized portion extends in a first direction that is parallel to the bottom 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 disposed adjacent to the crystallized portion in a second direction that is orthogonal to the first direction.
