Abstract
The interfacial joint area of a target/backing plate assembly is sealed so as to inhibit the migration of air and/or water vapor that may be present or trapped along the interfacial surfaces. A pool or bead of molten solder is placed along the interfacial joint and moved continuously around the full 360° circumference of the assembly so as to cover and seal the boundary area. The solder is melted, preferably, by e-beam welding in a vacuum or the like.
