Performances of conventional thick-film resistors subjected to mechanical straining

Low‐Frequency Noise and Resistance as Reliability Indicators of Mechanically and Electrically Strained Thick‐Film Resistors

“…In a case of thick-film resistors subjected to mechanical straining, resistance changes are caused by changes in physical dimensions and more dominantly by changes on micro-structural level resulting in increasing resistance values [5,16]. On the other hand, simultaneous mechanical and electrical straining has opposing effects on performances of thick-film resistors [16].…”

“…Investigations of mechanical and electrical straining of thick-film resistors showed that these two types of straining have opposite effects on behaviour of these complex nanostructures [5,20,21]. Examining effects of the simultaneous impact of mechanical and electrical straining on thick-film resistors [16] is of particular interest for sensitive equipment exploitation since simultaneous mechanical and electrical straining may affect resistors capability to withstand high-voltage treatment.…”

“…Mechanical straining causes a reversible resistance change in thick-film resistors [5,16]. The reversible resistance change is partially due to change in resistor geometry but mainly due to micro-structure changes.…”

“…On the other hand, standard thick-film resistors are being continuously used in contemporary electronic equipment that requires high functional capability, improved reliability and environmental stability. These up-to-date applications induced the need to examine performances of standard mechanically strained thick-film resistive structures [5,16].…”

“…The most of the published data dealt with effects of mechanical straining on performances of these complex heterogeneous systems using the piezoresistive effect in thick resistive films for strain gauge realization [1,2]. On the other hand, performances of standard thick resistive films subjected to unwanted mechanical straining [3][4][5] have not been sufficiently investigated despite the fact that mechanical straining may take place during all phases of resistor realization, examination and application. In case of high-voltage pulse stressing, the most of the papers investigated effects of trimming of thick resistive films by energy of high-voltage pulses [6][7][8] and behavioural analysis of surge thick-film resistors [9].…”
