The article presents a method for controlling defects in the layering of multilayer printed circuit boards based on the use of acoustic emission and the study of the propagation of acoustic signals in the sample under study. It is shown that the proposed method, combining modeling, physical experiment and machine learning technologies in data processing, can become an effective tool for express control of multilayer printed circuit boards at the stage of their production. The article presents the structure of the method with a functional description of individual modules and blocks, shows the connection between computational and physical experiments, and the software used. The article also reflects the results of a study to assess the influence of the structure and number of layers of a multilayer board on the duration of a model experiment. In addition, the results of a study to determine the permissible range of variation in the characteristics of acoustic emission signals for a serviceable sample of a printed circuit board are presented, which made it possible to take into account in the model experiment the spread of parameters of printed circuit board materials and technological processes of their production. The research results presented in the article can be useful for design engineers, designers involved in the development of components and modules of radio electronic devices, specialists in the field of control and diagnostics of technical systems, students and postgraduates engaged in research in this field.
