MEANS OF IMPLEMENTING A NON-CONTACT METHOD FOR MEASURING TEMPERATURE DURING NON-DESTRUCTIVE TESTING OF THERMAL MODES OF ELECTRONIC MEANS

Background. In the process of designing, testing and using electronic devices, the use of specialized temperature measuring devices is often mandatory. Depending on the stage of the life cycle of electronic equipment, different types of meters based on different physical principles of operation can be used. Modern metrology identifies two fundamental approaches to temperature measurement: the contact method (with direct interaction with an object) and the non–contact method (non-destructive testing). This study focuses on contactless measurement techniques, and provides a detailed analysis of two different types of contactless measuring devices, each with unique characteristics and applications. Materials and methods. The research is based on the theoretical and practical aspects of the process of non-destructive temperature control and the methodology of thermophysical design of electronic equipment and devices. Results and conclusions. The advantages and disadvantages of pyrometric and thermal non–contact temperature meters are considered in detail, an example of a modern integrated pyrometric meter is given, and two of the most common electronic devices for non-contact temperature measurements are considered – a pyrometer and a thermal imager. In conclusion, the authors substantiate the use of an information and measuring system for non-destructive temperature control in the design of radioelectronic devices, together with software tools for thermophysical design.
