Abstract

The invention discloses a high-damping high-thermal-conductivity gold alloy for bonding wires in electronic fields and a technic thereof. The alloy comprises the following components of, in percentageby weight, 20.0-25.0wt.% of Mn, 4.0-5.0wt.% of Fe, 1.0-2.0wt.% of Ni, 0.4-0.6wt.% of Ge, 0.1-0.2wt.% of Sc, 0.2-0.4wt.% of Ru, 2.0-3.0wt.% of Sn, 0.1-0.2wt.% of Be and the balance Au. The gold alloyprovides a solution which is different from that of a traditional material for gold alloy bonding wires which work in electronic devices with obvious vibration, so that the current situation that existing gold bonding wires do not have damping performance can be effectively overcome. It is predicted that implementation and industrialization of the gold alloy not only can effectively avoid fatiguedamage to the gold bonding wires caused by vibration, but also can obtain great social benefits and economic benefits.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] With the continuous development of industrial production and the increasing number of various industrial machinery, the hazards and pollution caused by various vibrations and noises are becoming more and more serious. Noise is always accompanied by vibration, and the resulting noise pollution has become a kind of environmental pollution that is very harmful to human beings. The creation and widespread use of various equipment and machinery, in addition to bringing prosperity to the market and improving people's living standards, has also increasingly seriously affected all aspects of the industrial field and people's physical and mental health. [0003] The impact and friction between various mechanical parts in the transportation field and industrial production are the main source of vibration. In addition, high-speed or high-pressure...
