Abstract

The lifetime of non-compliant eutectic solder joints was improved by an order magnitude by rapid quenching. The quenching produces a fine equiaxed superplastic grain structure which lowers the stresses in the solder joints for the fatigue cycle strain range. Similarly, compliant J Bend and Gull wing joints, which last thousands of cycles, operate at lower stresses where superplastic deformation predominates.
