Research of electronic devices taking into account electromagnetic compatibility

In this article methods and means of ensuring electromagnetic compatibility were considered, which can be used to reduce the effect of crosstalk between conductors on the device board. We analyzed the causes and mechanism of crosstalk, which can disrupt the correct operation of the device due to a change in the logic level of the signal on the victim conductor due to the effect of crosstalk pickup on it. The simulation of the influence of interference on the signal in the passive line was automated depending with the distance between conductors, the length of the adjacent section of conductors, and conductor materials. For the study, a logical circuit of an electronic device, in particular encoder, and a printed circuit board were built. Experiments were carried out using the following data: conductor thickness of 5, 6 and 1.2 mils, conductor spacing of 5 and 6 mils, adjacent conductor lengths of 4340. 2020, 1620, 1050, 630, 320 and 300 mils, and materials conductors that have different values of specific electrical conductivity: silver (62,500,000 S/m), copper (5950,000 S/m), platinum (10,000,000 S/m), gold (43,000,000 S/m), nickel (15,000,000 S/m), aluminum (35*106 S/m), steel (1400000 S/m). The data on the values of crosstalk were obtained. Research performed at the designed logic circuit electronic device and its circuit board. The data on the values of crosstalk were obtained according to the constructed reports. In the course of these studies, the dependences of an increase in the value of crosstalk on an increase in the length of adjacent sections, a decrease in the distance between conductors.
