2. Description of the Related Art From the viewpoint of high-density mounting, the mounting method of a semiconductor device has shifted from the conventional pin insertion method to a surface mounting method. Since reflow soldering is used and the package is heated to a high temperature of 200 ° C. or more, package cracks occur due to rapid vaporization / expansion of moisture contained in the package, particularly in the adhesive layer or the sealing material, There is a problem that the reliability of the semiconductor device is reduced. This problem was particularly acute with copper leadframes than with 42 alloy leadframes.
