ABSTRACT:
A continuous process for solid-phase edge bonding a plurality of dissimilar metal strips to form a composite edge-bonded strip. A plurality of elongated metal strips of equal thickness are heated and aligned in a substantially planar, edge-to-edge relationship and pass through a pair of compression bonding rollers. The bonding roller form a rectangular-shaped cavity having a width slightly greater than the combined width of the plurality of strips and a height less than that of the strips, to reduce in thickness and further elongate the metal strips without substantially changing the combined width of the strips and to form a solid-phase bond between adjacent side edges of the strips. The strength of the solid-phase bond is substantially equal to that of the parent metal strips such that the composite strip can be cut or stamped to form detail component parts such as electronic lead frames without bond failure.
