ABSTRACT:
An apparatus for predicting a deformation of a board includes a board dividing unit that divides the board into a plurality of areas based on wiring information on the board; and 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 and a coefficient of thermal expansion 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 divided by the board dividing unit.
