Patent ID: 7596477

Claim:
A peel strength simulating apparatus which simulates peel strength between a semiconductor integrated circuit chip and a resin package bonded to each other, the peel strength simulating apparatus comprising: a storage section which stores a parameter table where plural types of parameters are each associated with a changeable numerical range of a parameter or a group of numerical values of a parameter in the parameter table; a parameter specifying section which specifies, before simulation starts, a changeable parameter whose numerical value is changeable from the plural types of parameters in the parameter table stored in the storage section, the parameter specifying section specifying change priorities when specifying plural types of changeable parameters; and a simulating section which automatically repeats simulation of the peel strength until the peel strength exceeding a predetermined threshold value is obtained while automatically changing, without waiting for an operation by an operator, the numerical values of the changeable parameters specified by the parameter specifying section according to the priorities specified by the parameter specifying section.
