Board Terminal Electrode Layout for Multi-Size Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing board terminal electrode components require multiple configurations to accommodate two-terminal electrode components of different sizes, leading to increased manufacturing costs and inefficiencies.
Innovation Solution
A board terminal electrode component design featuring a pair of land pads with expanding width portions and insulators, allowing for the mounting of two-terminal electrode components of varying sizes by adjusting the width and placement of these pads to accommodate different sizes, thereby reducing manufacturing costs and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between electrode pads is changed to accommodate different sizes of two-terminal electrode components, then the components of different sizes can be mounted, but the manufacturing cost increases and replacement efficiency decreases
Solution Approach 1:
The land pad structure is designed to serve multiple functions: it provides a mounting surface for components of different sizes, maintains electrical connection, and ensures mechanical stability. The expanding width portion allows the same land pad to accommodate both small and large components without requiring different pad configurations, thus achieving universality.
Solution Approach 2:
The land pad features a non-uniform width structure with an expanding width portion. The width varies along the arrangement direction, with the first width at the first end, intermediate width in the middle, and second width at the second end. This local variation in geometry allows the land pad to adapt to different component sizes while maintaining a single standardized design.
2Adaptability or versatility
If multiple land pad configurations are used to accommodate different component sizes, then all component sizes can be mounted, but the device complexity increases
Solution Approach 1:
A single land pad design with expanding width portions replaces the need for multiple specialized land pad configurations. This universal design maintains electrical and mechanical functionality across different component sizes while reducing the variety of configurations to just one standardized type.
Solution Approach 2:
The land pad combines multiple geometric features (first width portion, expanding width portion, second width portion) into a single integrated structure. This merging of features allows the land pad to perform multiple functions - accommodating different component sizes, providing electrical connection, and ensuring mechanical stability - without requiring separate structures for each function.

AI summary
A board terminal electrode component includes a board, and a pair of land pads spaced apart from each other on a surface of the substrate. The pair of land pads respectively include inner ends which are proximal to each other in an arrangement direction, and outer ends farther from each other in the arrangement direction than the inner ends. The pair of land pads respectively include expanding width portions expanding in a width direction from the inner end toward the outer end. The pair of land pads respectively include insulators on a surface of an end portion of the outer end of the land pads.
