Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermal interface material is used to fill gaps between the pressing mechanism and electronic component, then heat dissipation is improved, but the system cannot detect when the thermal interface material deteriorates
Solution Approach 1:
The patent incorporates temperature sensing units and monitoring circuits that continuously measure the temperature at the thermal interface between the pressing mechanism and electronic component. This preliminary monitoring detects thermal interface material deterioration before it causes component failure, allowing proactive maintenance or replacement of the thermal interface material.
2Reliability
If real-time monitoring of thermal interface quality is implemented, then component failure is prevented, but device complexity increases
Solution Approach 1:
The patent integrates temperature sensing units and monitoring circuits into the existing inspection device structure, allowing the same device to perform both its primary inspection function and thermal interface monitoring function. This multi-functionality reduces the need for separate dedicated monitoring equipment, thereby limiting the increase in device complexity while achieving real-time thermal interface quality monitoring.

AI summary
An inspection system with a thermal interface, and an electronic component inspection device and method are provided. First, a temperature regulator contacts an electronic component to be tested, where there is a thermal interface between the temperature regulator and the electronic component to be tested, and the electronic component to be tested includes a plurality of temperature sensing units. Then, the temperature regulator heats or cools the electronic component to be tested to a specific temperature, and the plurality of temperature sensing units of the electronic component to be tested detect temperatures at locations of the temperature sensing units. In this way, a contact condition between the temperature regulator and the electronic component to be tested, and quality or an aging status of the thermal interface can be determined.
