Electrical characterization of individual metal-coated polymer spheres used in isotropic conductive adhesives
Nguyen, Hoang-Vu; He, Jianying; Helland, Tore; Kristiansen, Helge; Aasmundtveit, Knut Eilif (Journal article; Peer reviewed, 2016)Isotropic conductive adhesives (ICAs) filled with metal-coated polymer spheres (MPS) have been proposed to improve the mechanical reliability compared to conventional ICAs filled with silver flakes. The electrical properties ... -
Fracture of micrometre-sized Ni/Au coated polymer particles
He, Jianying; Helland, Tore; Zhang, Zhiliang; Kristiansen, H (Journal article; Peer reviewed, 2009)Deformation and fracture of individual micrometre-sized Ni/Au coated polymer particles have been studied by a nanoindentation-based flat punch method. A wide range of test conditions has been applied to deform the coated ...
