Abstract
A low temperature target and backing plate bonding process and assemblies made thereby. A plurality of projections are formed in the harder member of the assembly. The assembly is bonded by conventional techniques around the peripheral assembly boundaries. The assembly is then pressure consolidated at low temperature so that the projections, circumscribed by the bonded zone, penetrate into the softer member promoting the formation of metal to metal cold diffusion type bonds.
