Abstract

A highly adaptive thermal properties measurement system and measuring method thereof, for measuring various thermal property values of a device under test without actually lighting up the device under test, are disclosed. The measurement system includes a light source unit, a light modulation module, a holding unit, a thermal reflection unit, a thermal signal capture unit, and a control and computation unit. A light field provided from the light source unit is first modulated by the light modulation module for its distribution of intensity, and then illuminates on the device under test such that the device under test is heated in a specific mode so as to simulate a temperature distribution of the device under test in a state of continuous operation. Further, the control and computation unit computes various thermal property values of the device under test based on a top-surface thermal signal and a bottom-surface thermal signal captured by the thermal signal capture unit.

First claim

What is claimed is:

1. A highly adaptive thermal properties measurement system, provided for measuring plural thermal property values of a device under test having a top surface and a bottom surface, comprising:
a light source unit, provided for supplying a light field;
a light modulation module, provided for modulating distribution of intensity of the light field;
a holding unit, provided for holding the device under test;
a thermal reflection unit, being arranged toward th…
