CONDUCTOR FORMATION METHOD FOR MAGNETIC HEAD TRANSDUCER, SOLDERED COUPLING, HEAD SUSPENSION ASSEMBLY, AND MAGNETIC RECORDING DISK FILE

摘要

PROBLEM TO BE SOLVED: To provide a method for forming an electric soldered joint between a thin film magnetic transducer and a conductor of a joint suspension after mechanically attaching the thin film magnetic transducer to the suspension, and further provide such soldered coupling, a head suspension assembly including the thin film magnetic head transducer, and a magnetic recording disk file including the head suspension assembly. SOLUTION: A solder ball 32 is disposed between an end pad 18 of a thin film magnetic head and a lead pad 28 of a conductor by means of a capillary tube 32. The solder ball is irradiated with a converged laser beam 34 to be reflowed. The resulting soldered joint provides a pair of extremely thin layers made of an intermediate compound in a region which is in contact with the thin film magnetic head and the end pad.
