Sintering Mechanisms in Base Metal Conductors

[摘要] Thick film conductors based on Al, Cu and Ni have been studied. Because of its high depth of field, a SEM wasused to study the microstructures of the fired conductors.Because of the very small size of the particles in commercial Cu pastes the neck growth forms part of the graingrowth mechanism.The bonding between the particles is much stronger in Cu than in Al films; this seems to be the reason why thesheet resistance of a Cu film virtually reaches the theoretical minimum.
