Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G antenna testing equipment requires customization for different semiconductor packages, leading to high costs due to the need for replacing circuit boxes, which is inefficient and costly for testing various antenna structures.
Innovation Solution
A modular testing device with a detachable cylinder and carrier cover, integrated into a testing head, allows for the same testing head to be used across different antenna structures by replacing only the cylinder, reducing the need for customizations and lowering costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the circuit box is customized for different semiconductor packages, then the testing accuracy is improved, but the equipment cost increases
Solution Approach 1:
The testing equipment is divided into two parts: a reusable testing head and replaceable circuit boxes. Each circuit box is designed for specific semiconductor packages (QFN, LGA, SiP, FCBGA, FCCSP), allowing accurate testing for each package type while sharing the expensive testing head infrastructure.
Solution Approach 2:
The testing head is designed with universal functionality to accommodate different circuit boxes for various semiconductor packages. The testing head includes a cavity that can hold different types of circuit boxes, and a handler that can press different packages onto different circuit boxes, making the expensive testing head reusable across multiple package types.
2Adaptability or versatility
If the circuit box is replaced for different semiconductor packages, then the testing versatility is improved, but the device complexity increases
Solution Approach 1:
The system is segmented into a permanent testing head and replaceable circuit boxes. Each circuit box is optimized for specific package types, while the testing head remains constant. This segmentation allows versatility through circuit box replacement without complicating the overall testing head design.
Solution Approach 2:
The circuit box acts as an intermediary component between the semiconductor package and the testing head. It provides the necessary electrical connections and mechanical support for different package types, while the testing head maintains a consistent structure. This intermediary approach enables versatility without requiring changes to the complex testing head.
3Measurement precision
If the testing head is customized for different antenna structures, then the testing precision is improved, but the productivity decreases
Solution Approach 1:
The testing system is segmented into a reusable testing head and replaceable circuit boxes. Each circuit box can be optimized for specific antenna package types (QFN, LGA, SiP, FCBGA, FCCSP), ensuring precise testing for each type. The reusable testing head maintains consistent testing conditions while the circuit boxes are quickly swapped to match different antenna structures, preserving both precision and productivity.
Solution Approach 2:
The system introduces dynamic adaptability through replaceable circuit boxes while keeping the testing head static. The circuit boxes can be quickly changed to match different antenna package types, allowing the system to adapt to different testing requirements without redesigning the entire testing head. This dynamic approach maintains precision for each package type while improving productivity through rapid circuit box replacement.

AI summary
Testing equipment is used in an antenna testing process, and includes a testing head having a perforation, and a testing device having a cylinder. The cylinder is disposed in the perforation to act as a cavity for the antenna testing process. Therefore, only the cylinder needs to be replaced when the antenna testing process is performed on different devices under test, with the whole testing head intact.
