In a structure 21 for connecting an electric wire and a connecting terminal in the invention, a ductile metal film 29 is formed in advance on an inner surface of a conductor caulking portion 24 of a crimp terminal 22 by such as plating, vacuum deposition, or adhesion. Then, the conductor caulking portion 24 in the rear portion of the crimp terminal 22 is caulked onto core wire portions M in a state of being stripped and extended in the axial direction from an end of a sheathed wire W to thereby establish connection.

A method and structure for a solder interconnection, using solder balls for making a low temperature chip attachment directly to any of the higher levels of packaging substrate is disclosed. After a solder ball has been formed using standard methods it is reflowed to give the solder ball a smooth surface. A layer of low melting point metal, such as, bismuth, indium or tin, preferably, pure tin, is deposited on the top of the solder balls. This structure results in localizing of the eutectic alloy, formed upon subsequent low temperature joining cycle, to the top of the high melting solder ball even after multiple low temperature reflow cycles. This method does not need tinning of the substrate to which the chip is to be joined, which makes this method economical. It has also been noticed that whenever temperature is raised slightly above the eutectic temperature, the structure always forms a liquid fillet around the joint with copper wires. This liquid fillet formation results in substantial thermal fatigue life improvement for reduced stress at interface; and secondly, provides an easy means to remove chip for the purpose of chip burn-in, replacement or field repairs.
