摘要: A composite layer composed of an Ni layer 72 and a Pd layer 73 is formed on a solder pad 77U, and a solder 76α on the composite layer is composed of a solder containing no lead. Because a Pd layer (palladium layer) reduces phenomenons such as repellency of the solder, adhesiveness with the solder can be enhanced. Because a Pd layer has a higher degree of rigidity than a gold layer, thermal stress is absorbed into the Pd layer and buffered so as to reduce the degree of transmission of stress to the solder bump, or to the solder layer, by means of thermal stress.
