Abstract : The topography of solidified solder surfaces was investigated using electron microscopy. It is shown that 'ripples' which sometimes form on the surface are caused by the presence of an oxide film. Similar ripples were observed on the walls of a crater produced by high-velocity impact. It was concluded that localized melting of the target had occurred during impact. (Author)
