Patent ID: 7139678

Claim:
An apparatus for predicting a deformation of a board, the apparatus comprising: an input unit that inputs computer aided design data and matrix physical property values to the apparatus; a board dividing unit that divides the board into a plurality of areas based on wiring information on the board; a deformation predicting unit that grasps a wiring pattern of an area macroscopically, calculates an equivalent physical property value equivalent to a modulus of longitudinal elasticity for each of the plurality of areas of the board and a coefficient of thermal expansion for each of the plurality of areas of the board by a finite element method, and predicts the deformation of the board based on the equivalent physical property value calculated for each of the areas of the board divided by the board dividing unit; and a results generating unit that generates results containing information regarding the predicted deformation of the board, wherein the results are used to take measures for preventing deformation from occurring in advance.
