The non-linear electro-ultrasonic spectroscopy was used as a non-destructive testing method for the polymer based and cermet thick film resistors evaluation. We carried out the correlation between this method and standard testing methods as noise spectroscopy and the third harmonic voltage measurements. The measuring set-up with the ultrasonic transducer working on the frequency range 10 kHz to...

Results of thorough experimental studies on electrical properties of thick-film resistors (TFRs) have been overviewed and summarized. Experiments covered resistance and noise measurements in wide temperature range. Low-frequency noise spectroscopy has been used for the investigations of fluctuating phenomena. Sample resistors were prepared of various combinations of commercial and laboratory-ma...

The paper presents some results of the experiments with IEEE 1149.4 KLIC Test Chip in the area of active RC filters implemented in thick-film hybrid technology. The influence of analog boundary modules (ABMs) on circuit performance is analysed in the case study of active RC notch filter. INTRODUCTION In this paper we present some results of the experiments with IEEE 1149.4 KLIC Test Chip in the...

LTCC technology is based on sintering of multi-layered thick-film sheets (50-250μm) or so-called green tapes, which are screen-printed with thick-film pastes such as conductors, resistors, etc. The terms low temperature and co-fired originate from the relatively low sintering temperatures (<900°C) compared to conventional ceramics and simultaneous firing of tapes together with screen-printed th...
