Abstract
A process for bonding one or more target parts, such as yttrium oxide target parts, to a copper backing plate to provide improved mechanical support and improved heat transfer. The process is one in which a noble metal, preferably platinum, is applied to the target to provide an oxide free layer to which indium/lead solder joins. The solder step is performed so that contamination by flux or by formation of an oxide is prevented.
