Title:
RECORDING MEDIUM AND THERMAL ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/006015
Kind Code:
A1
Abstract:
This computer-readable recording medium records a thermal analysis program for a resistor, for causing a computer that analyzes a temperature of the resistor to execute a process for preparing a thermal analysis model for the resistor, a process for setting a specific value as the amount of heat generated by the resistor, and a process for analyzing the temperature of the resistor by using the thermal analysis model, wherein: the resistor comprises an insulating base member, a resistance body formed on the upper surface of the insulating base member, and a pair of electrodes formed on the outer surface of the insulating base member and electrically connected to the substrate; the resistor also has an intermediate part, which is a portion of the insulating base member that is separate from the substrate, and a pair of terminal parts connected to the substrate on both sides of the intermediate part; and the thermal analysis model of the resistor has a resistance body node simulating the resistance body, an intermediate node simulating the intermediate part, a pair of terminal part nodes simulating the respective terminal parts and serving as the origin of the heat path between the substrate and the terminal parts, a first thermal resistor connected between the intermediate node and the resistance body node, and a pair of second thermal resistors connected between the intermediate node and the respective terminal part nodes.
