Characterization of Sintered Ag Nanopowder Joints using Nanoindentation Tests

Chemické listy 105 (2011) S777-S778

Sandwiches consisting of copper disks with Ag nanopowder interlayer annealed at various temperatures from 200 to 350 degrees C were studied. The main emphasis was placed on the characterization of quality of the sintered Ag layers by means of nanoindentation experiments. The highest hardness values were obtained after annealing at 350 degrees C. The highest values of the Young's modulus were achieved after annealing at 250 degrees C, indicating the lowest porosity of the sintered layer.
