Single Seal Loading Structure for Direct Fluid Device Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional direct fluid cooling methods for device testing face challenges with complex sealing requirements due to high thermal densities and 3D packaging, leading to unreliable and costly solutions with multiple seals, which limit design flexibility and increase tooling costs.
Innovation Solution
A system utilizing a single seal member arranged between two loading components, allowing independent motion and adaptation to various products, with the seal member being fully adjustable and self-retaining to provide a sealed environment for direct fluid interaction with the device under test.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sealing elements are employed to provide independent die and package loading, then the sealing reliability is improved, but the device complexity and tooling cost increase
Solution Approach 1:
The patent combines multiple sealing functions into a single seal member that simultaneously seals both the die loading area and package loading area. This single seal member integrates the functionality of what would traditionally require multiple separate sealing elements, thereby reducing structural complexity while maintaining comprehensive sealing coverage for independent loading operations
Solution Approach 2:
The seal member is designed with multi-functional capability to perform multiple sealing tasks simultaneously. It provides sealing for both die and package loading operations through a single component, eliminating the need for product-specific custom seals and reducing tooling costs while maintaining sealing reliability across different loading scenarios
2Manufacturing precision
If custom seals per product are used, then the sealing precision is improved, but the tooling cost and manufacturing complexity increase
Solution Approach 1:
The seal member is designed as a universal component that can accommodate multiple products and loading configurations without requiring custom tooling for each product. The standardized design maintains adequate sealing precision while dramatically reducing tooling costs and manufacturing complexity compared to product-specific custom seals
3Area of stationary object
If multiple seals are used to encompass both package and thermal head, then the sealing coverage is improved, but the design flexibility is reduced
Solution Approach 1:
The patent merges multiple sealing zones into a single integrated seal member that covers both the package loading area and thermal head area. This unified approach maintains comprehensive sealing coverage while providing design flexibility, as the single seal member can be adjusted and configured for different loading requirements without being constrained by multiple fixed sealing positions

AI summary
The present disclosure is directed to a system having a first loading component and a second loading component for applying load to a device during a test of the device, the first loading component is configured to be moveable with respect to the second loading component. The system includes a seal member arranged between the first loading component and the second loading component, the seal member is adapted to engage the device during testing so as to apply a load against the device during testing and provide sealing around a cavity positioned below the first loading component and above the device.
