The traditional cycle of manufacturing high-tech electronic products was examined, and a methodology for its optimization was developed. The interrelation between the stages of design documentation development and the electronic structure of the product was established. The methodology significantly reduced the manufacturing time of products by parallel development of the electronic structure alongside the product. The rationale for applying the methodology in design was provided.

The paper presents a theoretical study of spinodal and binodal decomposition of binary solutions. Since there is no thermodynamic barrier in spinodal decomposition, phase decomposition is determined only by diffusion. Thus, at decay many features of phase decomposition can be described by the analytical solution. The equations of spinodal and binodal decomposition in solutions without structural phase transitions are obtained.
