Context. The determination of the size of printed circuit boards is an important step in the design process of electronic and radio- electronic equipment, since its correct determination affects on both characteristics of quality and operational reliability, as well as economic and performance characteristics. In spite of multitude works devoted to these questions, there are no methods that objectively consider all multitude factors that affect the sizes, and at the same time are convenient to use. Therefore, in practice, the experience of developers is used, as well as the well-known requirements and limitations for the designed equipment. However, this approach does not lead to optimal results when determining the dimensions of printed circuit boards.
Objective. The aim of the work is to create a model of electronic modules based on printed circuit boards and a method for determining their sizes, and in particular fill factor, taking into account multitude acting factors and the application of standard sizes of printed circuit boards.
The method for determining the size of PCBs takes into account the influence of the installation area of electronic components and the duty cycle, which is distinguished by the fact that the dependence of the short circuit on the dimensions of electronic components and their density on the printed circuit board is established, as well as the dependence of the input proportionality coefficient on the area of printed circuit boards when using their standard sizes.
Results. Created the model of electronic modules based on printed circuit boards and a method for determining their sizes, which allows with minimum costs to determine the size of printed circuit boards at an early stages of design with limited initial data, as well as restrictions on the standard sizes of printed circuit boards established by corresponding standards and other regulatory documents.
Conclusions. As a result of theoretical studies was solved an important scientific and practical problem of increasing the efficiency of printed circuit boards design: the model and method for determining the dimensions of printed circuit boards were further developed taking into account many factors determining their area and sizes. The method are based on the established dependency between the fill factor and the installation area of electronic components for different values of the density of their placement on the printed circuit board. This allows to determine the size of printed circuit boards with minimal time.
Interconnection has also been established between the area required for the designed electronic module and the losses associated with the requirements for using standard types of printed circuit boards and expressed by the coefficient of proportionality.
The practical value of the got results is in their readiness for use by developers to determine the size of printed circuit boards that is demonstrated by the corresponding example.
