High energy pulse generator in research of mosaic heater system

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, that temperature field is one of the major factor which determines the proper exploitation parameters of different kind microcircuits, for example in thick-film gas sensors which were the subject-matter of presented research. The flat temperature distribution or even field with regions of different temperature values is required in many cases. It is impossible to achieve it using single heater. From this reason, the mosaic structure of resistive elements was taken into consideration. The presented high energy pulse generator and control system (adequate for matrix arrangement of elements) can be used in above-mentioned heating systems.
