In design and production of many electrical sensors barriers, which separate contact system and sensitive element are used. These barriers are of different materials depending on operation environment and functionality. In automotive high temperature sensors the main material is cement which does not allow humidity and ensure protection of contact system. A test method for hardness of high temperature...
Glass is the most used high-temperature protective layer in electronics and microelectronics. Reliability of the devices extremely depends on glass compactness and solidity. In this paper we present a test method for controlling glass solidity and compactness. In this case glass is protective layer for high-temperature sensor in automotive applications. The test method includes protective glass layer...
In electronics and sensor mounting technology, the reliability and quality of the modules depends on electrical contacts. Technologically this is a process of mechanical assembly and soldering/welding. The quality of contact depends on applied process parameters and human factor in both production steps. In this paper we investigate influence of different process parameters over the assembly of precise...
For matrices whose eigenvalues are real (such as Hermitian or real symmetric matrices), we derive simple explicit estimates for the maximal (λmax) and the minimal (λmin) eigenvalues in terms of determinants of order less than 3. For 3 × 3 matrices, we derive sharper estimates, which use det A but do not require to solve cubic equations.
