Further improvement of Pb/Cd-free CaRuO3 thick-film resistors

nr katalogowy: 58408

Thick-film resistors (TFRs) are very popular in many fields of electronics. They are typically made from pastes containing conducting (RuO2, Bi2Ru2O7 or CaRuO3) and Pb-containing glass components as well as organic vehicle, which are screen-printed on substrates and then fired in low or high temperature processes. TFRs gained many proponents over years of their usage, due to their advantages, as cheap technology, good performance parameters, and easy control of sheet resistance. On the other hand, RuO2-based resistors enter very demanding field of temperature sensing in cryogenics. Novel technique called printing electronics, in conjunction with eco-friendly materials, opens new page and makes thick-film technology still perspective. However, it implies design of new materials, like Pb/Cd-free solders and pastes for TFRs, what is challenge for technologists who have to develop new generation of materials. For example, well known and widely used in TFRs fabrication RuO2-based resistive pastes include lead-borosilicate glass and therefore they do not fulfill RoHS directive and have to be replaced with their Pb/Cd-free counterparts. Unfortunately, in spite of great effort, Pb/Cd-free TFRs are still at the explorative stage [1-5]. However, first attempts, suggest that CaRuO3 better works with Pb/Cd-free glasses [4] and therefore it is more promising conducting component than widely used RuO2. On the other hand, currently Pb/Cd-free CaRuO3-based TFRs are noisier than Pb/Cd-free RuO2-based or Pb-containing TFRs and form bad interface at least with Pb/Cd-free AgPd-based, contacts [6]. In this work we present our new results concerning studies of electrical properties of Pb/Cd-free CaRuO3-based TFRs. The innovation is that the resistive paste was made of the conducting component which is the mixture 1:1 of CaRuO3 and RuO2 powders. Resistance vs. temperature measurements and low-frequency noise spectroscopy methods have been applie[...]
