ABSTRACT:
An improved method for thermo-compression diffusion bonding allows bonding of a compliant metallic member to a second metallic member which may have surface irregularities. Opposite surfaces of the compliant metallic member are contacted by a layer of compactible material and by the second metallic member, respectively, such that distribution of a loading force applied to this assembly conforms the compliant member to the irregularities in the surface contour of the second metallic member. Thus, a uniform substantially void-free diffusion bond between the two metallic members is achieved.
