  • Publication number: 20110208485
    Abstract: A bonding surface extraction unit extracts, with reference to bonding information, data of a first bonding surface corresponding to a bottom surface of a bonding model from data of a first partial model and data of a second bonding surface corresponding to a top surface of the bonding model from data of a second partial model. The first partial model is a model of a pad included in a circuit board. The second partial model is a model of an electrode included in a component. The electrode is to be bonded to the pad with a bonding material. A bonding model generation unit generates a side surface establishing a link between outlines of the first bonding surface and the second bonding surface, and obtains data of the bonding model on the basis of a shape formed with the side surface, the first bonding surface, and the second bonding surface.

  • Publication number: 20040158450
    Abstract: The present invention relates to a solder joint life prediction method for predicting the joint life of joining solder which joins members with each other. It predicts the life of soldered joints with high accuracy in a short period of time. It observes phase growth in a crack pre-initiation stage, extrapolates the phase growth, and thereby predicts the time of crack initiation when an initial crack will appear in the joining solder. After the crack initiation, the present invention predicts the time of fracture using a simulation in which creep analysis is performed with a virtual initial crack given to data-based joining solder.
