Test Tray Fixing Unit for Semiconductor Insert Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional test trays for semiconductor devices require excessive space and multiple parts due to the need for two fixing units per insert module, leading to inefficiencies in testing capacity and production efficiency.
Innovation Solution
A test tray design that uses a single fixing unit to secure multiple adjacent insert modules to the frame, incorporating separation-preventing protrusions and guide structures to ensure proper alignment and secure fixation, allowing for efficient use of space and reduced part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two fixing units (screws) are used to install one insert module to the frame, then the insert module is securely fixed, but the number of parts and working hours increase
Solution Approach 1:
The patent merges multiple fixing functions into a single integrated fixing unit. The fixing unit comprises a first fixing member that secures the first insert module and a second fixing member that secures the second insert module, both integrated into one component rather than using separate screws for each insert module. This reduces the total number of parts while maintaining secure fixation of multiple insert modules.
2Reliability
If two fixing units are used per insert module, then secure fixation is achieved, but the space consumption and working hours increase
Solution Approach 1:
The fixing unit integrates multiple fixing members into a single compact structure that occupies less space than multiple separate fixing units. The first and second fixing members are arranged within one fixing unit footprint, reducing the overall space required for fixation while maintaining stable securing of multiple insert modules.
Solution Approach 2:
The fixing unit is designed as a multi-functional component that simultaneously performs the fixation of multiple insert modules (first insert module and second insert module) through its integrated first and second fixing members. This universal fixing unit replaces multiple single-purpose fixing units, reducing space consumption while maintaining fixation stability.
3Reliability
If multiple separate fixing units are used, then each insert module is individually secured, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent combines multiple individual fixing operations into a single assembly action. The integrated fixing unit with multiple fixing members allows simultaneous securing of multiple insert modules in one operation, rather than requiring separate assembly steps for each fixing unit. This significantly improves assembly efficiency while maintaining individual module security.

AI summary
A test tray for a test handler is disclosed that is loaded with semiconductor devices and then carries them along a predetermined circulation route. The test tray allows one fixing unit to fix a plurality of adjacent insert modules to the receiving spaces of the frame, thereby efficiently using the space of the frame and allowing a relatively large number of insert modules to be installed in the same area, in comparison to the conventional test tray.
