The invention provides a processing method based on isotropy homogenization of various isotropic materials. The method specifically comprises the steps that: an equivalent volume element is reasonablyselected in a multi-embedding region of a complex structure, each material in the volume element is an isotropic material, and the equivalent volume element serves as a new structure; and specific parameters of the structure in all directions are obtained again in an experiment or simulation mode, specifically, force/heat and other loads can be applied to the volume element, result data of the displacement/heat/force of the equivalent volume element (RVE) are collected, and the attributes of the anisotropic materials of the equivalent volume element are obtained through formula calculation. According to the method of the invention, the problems of large experimental value deviation and literature to simplify a multilayer nested packaging structure/material in a microelectronic product dueto the fact that an equiv
