Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current semiconductor test systems face inefficiencies due to prolonged test times and complex driving mechanisms, leading to wasted time in the testing process, which hampers the throughput of semiconductor component testing.
Innovation Solution
A test system employing rotational test arms that move semiconductor components between multiple test sockets and a transport device, allowing for simultaneous testing with different or identical test signals, optimized by using a YZ-coordinate mechanism for efficient movement and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple test sites are used to test semiconductor components, then testing capacity is improved, but the number of test arms and moving mechanisms increases, leading to increased device complexity
Solution Approach 1:
The patent combines multiple test sites (first test site and second test site) into a single integrated testing system where one test arm serves both sites. The test arm can move between different test sockets and perform testing operations at multiple sites without requiring separate test arms for each site, thereby reducing overall system complexity while maintaining enhanced testing capacity.
Solution Approach 2:
The test arm is designed with multi-functionality to serve multiple test sites. It can carry semiconductor components to different test sockets, perform various testing operations, and classify components based on test results. This universal design allows a single test arm to replace what would traditionally require multiple specialized test arms, reducing device complexity while improving productivity.
2Adaptability or versatility
If test arms repeatedly move semiconductor components between test sockets, then testing flexibility is improved, but moving time increases, leading to loss of time
Solution Approach 1:
The transport device is configured to pre-position semiconductor components in load sockets before the test arm needs them. This preliminary arrangement allows the test arm to efficiently retrieve components without excessive searching or repositioning time, reducing the overall moving time while maintaining the flexibility to test different components in various sequences.
Solution Approach 2:
The system enables continuous testing operations by having the test arm alternately serve multiple test sockets without returning to a home position between tests. The test arm can move directly from one test socket to another, performing testing operations continuously. This eliminates idle moving time and maintains testing flexibility across multiple sockets simultaneously.

AI summary
A test system with rotational test arms for testing semiconductor components includes a transport device, a first test socket, a second test socket, a first test arm, and a second test arm. The first test socket and the second test socket are electrically connected to different test signals respectively and correspond to the first test arm and the second test arm. The first test arm and the second test arm test arms operate rotationally to carry and place the semiconductor components to the transport device, the first test socket and the second test socket, so the test time is improved.
