Współczesne systemy czujnikowe wymagają często podwyższonej temperatury pracy. Bardzo dobrym przykładem takich struktur są czujniki gazu, w których wymaga się temperatury pracy nawet do 900°C. Zastosowanie technologii grubowarstwowej pozwala uzyskiwać systemy grzejne o wyjątkowo wysokich parametrach eksploatacyjnych. W pracy zaprezentowano wyniki symulacji rozkładu pola temperatury zarówno standardowych...
Poprawne ukształtowanie założonego rozkładu temperatury w mikroukładzie hybrydowym jest uwarunkowane bardzo wieloma czynnikami, związanymi zarówno z procesami wymiany ciepła jak i zmiennością parametrów zastosowanych materiałów oraz przyjętą, strukturą geometryczną. Uzyskanie pola temperatury o zróżnicowanych poziomach oraz zapewnienie jego niezmienności w rożnych warunkach pracy, jest możliwe jedynie...
One of the most important features of thick-film technology is a huge design flexibility of resistive and conductive elements on different types of substrate. Additionally, the very good heat conductivity of used substrates and low thermal capacity make this technology an excellent solution for manufacturing of wide range of different heaters with given temperature distribution. It can be emphasized,...
In modern electronic microcircuits the intended and unintentional dynamic changes of the temperature (for example caused be electrical signals) are very often observed. The good knowledge about these phenomena is the basis of lifetime and reliability determination in the real-world operating conditions. The presented pulse generator is very useful in researches connected with such problems especially...
The temperature influence (especially their irregular distribution in the digital chip structure) on proper operation of the microprocessor system has been presented in the paper. As the results of non-uniform heating of silicon structure the incorrect operation of selected functional blocks of single chip microprocessor can be observed. Especially, the circuits which operation is independent on global...
The theoretical analysis (compared with experimental investigations) of dynamic temperature states in layer microcircuits (made in LTCC or HTCC technology) has been described in the paper. Two basic models and solution procedures of analytical equations system have been presented. Furthermore their basic advantages and disadvantages have been compared together with accuracy discussion. The solution...
