Abstract
The present invention provides a peel strength simulating apparatus which simulates peel strength between a semiconductor integrated circuit chip and a resin package bonded to each other. The apparatus includes a storage section which stores plural types of parameters. The apparatus also includes a parameter specifying section which specifies a changeable parameter whose numerical value is changeable from the plural types of parameters stored in the storage section and specifies change priorities when specifying plural types of changeable parameters. The apparatus further includes a simulating section which repeats simulation of the peel strength until the peel strength exceeding a predetermined threshold value is obtained while changing the numerical values of the specified changeable parameters according to the specified priorities.
