Electronic Component Control Point for Visual Wetting Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic components lack a mechanism to visually verify the connection of electrical contacts with connection materials, making it difficult to ensure sufficient wetting and stable electrical and mechanical contact with a contact carrier.
Innovation Solution
The electronic component features a base body with a side surface containing a control point divided into two areas, where the second area is designed to be more wettable with connection material, allowing for visual inspection of the connection points' wetting status and forming a stable bond after curing, ensuring reliable electrical and mechanical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection points are placed on the underside of the component base body, then electrical contact with the component is enabled, but visual inspection of the connection quality becomes impossible
Solution Approach 1:
The patent creates a control point that is a visual copy or representation of the connection point's bonding state. The control point replicates the wetting behavior and bonding quality of the actual connection points, allowing visual inspection of the copied bonding state to infer the quality of the hidden connection points without direct observation.
Solution Approach 2:
The control point acts as an intermediary element that mediates between the hidden connection points and the visual inspection process. It provides an intermediate visual indicator that reflects the bonding quality of the connection points, enabling indirect observation of the connection quality through the control point's wetting state.
2Difficulty of detecting and measuring
If the entire side surface is made wettable, then visual inspection is possible, but connection material spreads too widely and bonding stability decreases
Solution Approach 1:
The patent applies local quality by creating a control point with specific localized wettable properties on the side surface, rather than making the entire side surface wettable. The control point has controlled wettability in a specific local area, allowing visual inspection while preventing excessive spread of connection material that would compromise bonding stability of the connection points.
Solution Approach 2:
The side surface is segmented into distinct functional areas: the control point area with specific wettable properties for visual inspection, and the connection point areas for electrical contact. This segmentation allows the control point to have enhanced wetting characteristics for visibility while the connection points maintain their bonding integrity without excessive material spread.
