Definitions

  • FIG. 10A is a scanning electron micrograph of a solder joint section of Comparative Example 2 after exposure to 150° C. for 500 hours;
  • the invention solder alloy can be bonded to various types of alloy electrodes. This is because when it is bonded to various types of alloy electrodes, even if the Cu—Ni—Sn compound is exposed to a high temperature, Ag forms a compound with Sn to exhibit a pinning effect whereby enabling reduction of deterioration of bonding strength under such a high temperature.
