“…Another Ag paste consisting of 70 wt.% Ag particles of sizes ranging from nanometers to micrometers possessed an electrical resistivity of 4 9 10 À6 X cm to 11 9 10 À6 X cm after it was sintered at 400°C to 550°C. 26 Additionally, an inkjet-printed Ag film made from a silver ink with 60 wt.% metallic content and sintered at 250°C was reported to have an electrical resistivity of about 3.0 9 10 À6 X cm. 27 The higher electrical resistivity reported in our work was probably due to the presence of defects and cavities in the sintered paste.…”

A homogeneous electrically conductive silver paste without solid or particle phase was developed using silver alkylcarbamates [(C n H 2nÀ1 NHCOO) 2 Ag, n £ 4] as the precursor of the functional phase. The silver alkylcarbamates were light insensitive and had a low decomposition temperature (below 200°C). The paste was a non-Newtonian fluid with viscosity significantly depending on the content of the thickening agent ethyl cellulose. Array patterns with a resolution of 20 lm were obtained using this paste by a micropen direct-writing method. After the paste with about 48 wt.% silver methylcarbamate [(CH 3 NHCOO) 2 Ag] precursor was sintered at 180°C for 15 min, an electrically conductive network consisting of more than 95 wt.% silver was formed, and was found to have a volume electrical resistivity on the order of 10 À5 X cm and a sheet electrical resistivity on the order of 10 À2 -10 À3 X/h. The cohesion strength within the sintered paste and the adhesion strength between the sintered paste layer and the alumina ceramic substrate were tested according to test method B of the American Society for Testing and Materials standard D3359-08. None of the sintered paste layer was detached under the test conditions, and the cohesion and adhesion strengths met the highest grade according to the standard.

“…Considerable work has been conducted in the study of low temperature curing silver pastes, mainly related to the conductive and binder phases [11][12][13]. Xing et al [14] selected eight different types of resins as the binder phase of low temperature curing silver pastes; their experimental results showed that, at the same ratio, silver pastes composed of vinyl and acrylic resins had the lowest sheet resistance, those composed of polyester and epoxy resins had the best adhesion and highest hardness, and those composed of polyurethane had the best resistance to bending.…”

Four polyester resins with different molecular weights were used as the binder phase in silver pastes. The effects of the polyester resin molecular weight on the performance of low temperature curing silver pastes were investigated. With increasing molecular weight, the resistivity first decreased and then increased, and the sample that used a polyester resin with a weight-average molecular weight of approximately 150,000 had the lowest resistivity of 3.673 9 10 -7 X m. After folding and smoothing the sample 10 times, the silver paste that used polyester A as the binder phase had the lowest rate of resistance change of -6.70 %, and the reason for why these values were negative was investigated using scanning electron microscopy images of sample cross sections. The adhesions and stabilities of the samples were also tested.
