Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibration in IC testing apparatuses causes increased abrasion and maintenance costs due to inadequate damping, affecting the lifespan and efficiency of semiconductor components during testing.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed frame structure is adopted to prevent vibration, then the connection stability is improved, but the vibration cannot be completely eliminated and component abrasion increases
Solution Approach 1:
The patent converts the harmful vibration energy into beneficial damping effects by introducing a damping component that transforms vibrational mechanical energy into thermal energy through viscous fluid resistance and elastomer hysteresis, thereby eliminating vibrations that would otherwise cause abrasion while maintaining connection stability
Solution Approach 2:
The damping component employs a composite structure combining viscous fluid and damping elastomer materials with different damping coefficients. The fluid provides viscous damping through shear resistance, while the elastomer provides elastic damping through hysteresis, creating a synergistic effect that efficiently dissipates vibration energy across multiple mechanisms
2Object-generated harmful factors
If damping components are added to reduce vibration, then the abrasion is reduced, but the device complexity increases
Solution Approach 1:
The patent merges the damping function with the existing fixed frame structure by integrating the damping component into the support structure. The damping component is positioned to interact with the chip-testing socket and chip-mounting component, combining vibration damping with the existing mechanical support function rather than adding a separate independent damping system
Solution Approach 2:
The damping component acts as an intermediary element between the fixed frame structure and the tested components. It absorbs and dissipates vibration energy before it reaches the chip-testing socket and chip-mounting component, protecting these components from vibration-induced abrasion while maintaining the structural integrity of the testing apparatus
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The damping component effectively reduces vibration amplitude and absorption time, extending the lifespan of IC testing apparatus components, decreasing maintenance costs and enhancing operational stability.
Implementation Method 1
the oscillation of the fluid and the sliding piece induced by the force may undergo a damping oscillation while the sliding piece and the damping elastomer have different damping coefficients
Implementation Method 2
the force may further be transmitted to a fluid and a damping elastomer inside a housing of the damping component through the sliding piece
