The size of electronic devices is becoming miniaturized and performances are becoming more and more high function. So power consumption of the product is greatly increased. And, in the progress of product development, thermal design is a very important task. In the thermal design process, we need many climate chambers to measure temperature of electronic components and check operation of the products under cold and hot environments. However, the climate chamber needs expensive maintenance cost and occupies large space. This is a huge burden to the company.
Most developers replace high-temperature tests by low cost room temperature tests. There is an issue how much value the developers add to the results of room temperature tests for converting to the results of high temperature tests. In this paper, some results based on tests and thermal simulation analyses have been reported to suggest the value.
