Title:
ANALYSIS DEVICE, ANALYSIS METHOD AND ANALYSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2010/067415
Kind Code:
A1
Abstract:
A first generation unit (311) assumes that a circuit substrate is a lower layer and upper layer lamination body and sets the rate of thermal expansion of the circuit substrate itself actually measured in advance with the rate of thermal expansion of the lower layer regarded as α1. The first generation unit sets a value obtained from the Stoney formula with the rate of thermal expansion of the upper layer regarded as α2. The first generation unit divides the lower layer and the upper layer of the lamination body into a plurality of grid data and generates element divided data (334) in which positions of the grid data are made to correspond to materials. A second calculation unit (314) makes use of various solvers, calculates physical amounts occurred in analysis subjects in accordance with a finite element (335), and outputs an analysis result. That is, the second calculation unit (314) carries out a behavior simulation of the analysis subjects. This simulation is in an arbitrary temperature range set by a user.
