Reliability experiments on hybrid circuits are usually carried out by accelerated ageing test. The circuits or the components under test are stored at an elevated ambient temperature and the change of...
About the Influence of SiO2 on the Temperature Behaviour of Ruthenate Based Thick Film Resistors
SiO2 the Temperature Behaviour of Ruthenate Thick Film Resistors
2010/12/21
Substituting glass by SiO2 in thick film resistors results in a small increase of R□, a decrease of dR□/dT and an increase of d2R□/dT2 (at room temperature). From these experimental results it follows...
