Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mechanical structure of existing test section units in electronic device testing apparatuses is complex, leading to unfavorable electric characteristics such as long transmission line paths and limited circuit area, making it difficult to achieve high frequency transmission and current capacity.
Innovation Solution
A test section unit with a simplified mechanical structure that integrates multiple sockets directly onto a single performance board, eliminating the need for socket boards and allowing for the arrangement of peripheral circuits close to the sockets, with the option to stack sub-boards for increased circuit area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple socket boards and performance boards are used to provide sockets and peripheral circuits, then the circuit area can be increased, but the mechanical structure becomes complex and transmission line paths become long
Solution Approach 1:
The patent merges multiple socket boards and performance boards into a single integrated performance board that provides both sockets and peripheral circuits. This consolidation eliminates the need for multiple separate boards while maintaining the required circuit area, thereby simplifying the mechanical structure and reducing the number of connection interfaces.
Solution Approach 2:
The performance board is designed with distinct functional regions: a socket region for mounting electronic devices and a peripheral circuit region for mounting circuits. This segmentation allows both sockets and peripheral circuits to be provided on the same board while maintaining organized layout and short transmission line paths between the two regions.
2Device complexity
If socket boards are divided into two or more separate boards, then the mechanical structure can be managed, but electric characteristics such as high frequency transmission and current capacity deteriorate due to long transmission line paths
Solution Approach 1:
By combining the socket functionality and peripheral circuit functionality into a single performance board, the patent eliminates the need to divide socket boards into multiple separate boards. This integration ensures that transmission line paths between sockets and peripheral circuits remain short, thereby maintaining excellent electric characteristics including high frequency transmission and current capacity.
3Ease of operation
If sub boards are mounted upright vertically with respect to socket boards and performance board, then the structure fits the handler, but the mounting area of peripheral circuits is limited and cannot be easily increased
Solution Approach 1:
The patent eliminates the need for vertically mounted sub boards by integrating peripheral circuits directly onto the performance board in a planar configuration. This approach maintains compatibility with the handler while providing ample mounting area for peripheral circuits on the same board as the sockets, allowing easy expansion of circuit area without vertical stacking.
