Resumo

The article describes the development of mathematical model of plane strain of printed circuit board layers and experimental verification of its accuracy. The obtained experimental results qualitatively completely coincide with the calculation results; the quantitative discrepancy does not exceed 20%, which can be considered satisfactory at this step of clarifying the model coefficients taking into account random factors.
