Definitions
- FIG. 1 is a graph showing the eutectic point temperature of a binary alloy.
- the numerical value of the intersection point between the element on the vertical axis and the element on the horizontal axis indicates the eutectic point temperature of these two elements.
- the eutectic point temperature of the Sn—Ag alloy is 221 ° C.
- the eutectic point does not exist in the Ni—Cu alloy.
- the combination of elements whose eutectic point temperature is close to 275 ° C. can be narrowed down to two types, that is, a combination of Bi and Cu or a combination of Bi and Ge.
- FIG. 4 shows the relationship between the temperature at which the endothermic coefficient becomes 20% and the Cu content in a binary alloy containing Bi and Cu.
- the highly heat-resistant bonding material having a temperature at which the endothermic coefficient becomes 20% is 275 ° C. or higher has a Cu content of 2% by weight or more.
- the temperature at which the endothermic rate is 20% is 275.2 ° C. It can be seen that as the Cu content increases, the temperature at which the endothermic rate reaches 20% increases. When the Cu content exceeds 10.5% by weight, the temperature at which the endothermic rate becomes 20% is 282 ° C.
- FIG. 6 shows the relationship between the Ge content and the oxide generation amount in Bi-2.0 wt% Cu.
- the Bi amount decreases or increases.
- the amount of oxide produced is 58 g.
- the oxide generation amount is 52 g, and the effect starts to appear.
- the oxide formation is 42 g, 40 g and 45 g, respectively, and the effect is recognized.
- the oxide generation amount is 60 g, which is larger than the reference value of 58 g.
