Patent ID: 8850382

Claim:
An analysis apparatus for a printed circuit board comprising: a memory that stores printed circuit board model data of the printed circuit board including electronic parts on wiring layers having an external wiring layer and an internal wiring layer, and including an insulating layer between the wiring layers; and a processor that executes a process including: acquiring the printed circuit board model data; extracting, from the printed circuit board model data, electronic part data corresponding to a first electronic part mounted on the internal wiring layer and having a heat-generating attribute among the electronic parts; rewriting physical property data of a portion of the wiring layers to a value based on physical property data of the first electronic part, the portion of the wiring layers being in contact with the first electronic part; converting the physical property data of a portion of the wiring layers which the first electronic part occupies to physical property data of the insulating layer; changing the printed circuit board model data based on the converting; and performing a thermal analysis processing using the changed printed circuit board model data.
