“…A study by Jain et al [10] showed that 45 volume% is above the percolation threshold for ICA-1. In addition, ICA filled with 45 volume% of polymer spheres provides high die shear strength as presented earlier [2].…”

“…Details are described in the figure legend. While data for ICA-6M was available from our previous study [2], data for ICA-30M was lacked (at particle loading of 45 volume%). Therefore, we produced ICA-30M samples using the same assembly method and curing condition as applied for ICA-1.…”

“…The ICA consists of a commercial epoxy-based adhesive matrix filled with Ø30 μm silver-coated polymer spheres. The effect of the metal coating on the die shear strength is assessed by comparing with results from an earlier study using uncoated polymer spheres [2]. A conventional ICA, filled with Ag particles, is also included in the present study.…”

An isotropic conductive adhesive (ICA) filled with metalcoated polymer spheres (MPS) has been studied as a novel approach to increase the flexibility, and hence the reliability, compared to the conventional metal-filled ICA. In this study, the effect of the metal coating on the die shear strength was investigated by comparing ICA materials with coated and uncoated polymer spheres. The other important part of the study was to assess the temperature dependence of the die shear strength of an MPS-based ICA, and also compare this with the behavior of a conventional ICA filled with Ag particles. The results showed that the metal coating does not have a critical effect on the die shear strength of ICA filled with MPS. The die shear strengths obtained for the MPSbased ICA and the conventional Ag-filled ICA have the same temperature dependence in the range of 20 °C to 120 °C. Furthermore, none of the ICA systems has experienced a critical drop in die shear strength at and above the glass transition temperature.

The bidirectional 3[Formula: see text] method is an electrothermal technique that is commonly used to obtain the thermal conductivity of materials such as liquids, biological samples, and pastes. In this work, an epoxy-based adhesive was filled with monodisperse 10 μm polymethyl methacrylate spheres coated with silver thin films (AgPS), such that a metallic network that dominated the thermal transport was formed through the composite. The bidirectional 3[Formula: see text] method was used to obtain the thermal conductivity of the conductive adhesive at different volume fractions of AgPS. For 50 vol.% AgPS, corresponding to 3.4 vol.% silver, the thermal conductivity was [Formula: see text] W m−1 K−1. The results show that the thermal conductivity is strongly correlated with the AgPS volume fraction, while maintaining a volume fraction of silver far below the commercial silver paste, which has typical filler fractions of 40 vol.% silver. The results of this work were compared to thermal measurements of the same material by other techniques, and advantages and disadvantages of the methods were finally discussed.
