Abstract
The invention relates to a zirconium-gold-silver welding material and a preparation method thereof. The zirconium-gold-silver welding material comprises, by weight percentage, 10-15% of zirconium, 7-15% of silver, 2-5% of gold and the balance of tin. The zirconium-gold-silver welding material has the advantages that a multiple alloy method is used, zirconium, gold, silver and tin are combined according to different proportions, a stable intermediate phase is formed during alloying, and accordingly the melting point of the welding material is increased, and the conductivity of the welding material is also enhanced.
Description
Technical field
The present invention relates to a kind of metal alloy, relate in particular to a kind of zirconium gold and silver welding material and preparation method thereof.
Background technology
Along with the enhancing of people's environmental consciousness, electron trade is also improving the requirement of welding material.From 2006.7.1 day, completely forbid leaded electronic product import, adopt lead-free to become the main trend of electron trade.
At present, in the packaging technology of electronic product, for the welding that reaches a high temperature, still use leaded welding material, although also there is a small amount of improvement, such as adding the alloys such as gold, silver, the cost of welding material has also just improved very high.Therefore, the present invention is directed to the problems referred to above, invented one not only environmental protection but also resistant to elevated temperatures welding material.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of zirconium gold and silver welding material and preparation method thereof.
For solving prior art problem, the technical scheme that the present invention takes is: a kind of zirconium gold and silver welding material, comprises the constituent of following content by mass percentage: zirconium 10-15%, silver 7-15%, golden 2-5%, surplus is tin: zirconium 10-15%, silver 7-15%, golden 2-5%, surplus is tin.
The preparation method of described a kind of zirconium gold and silver welding material, comprises the following steps:
(1) by mass percent ratio, take four kinds of raw materials;
(2) raw material taking is placed in quartz ampoule, is evacuated down to sealed silica envelope after 3-5Pa;
(3) toward pouring 99% argon gas in quartz ampoule to (0.6-0.8) × 10
5pa;
(4) raw material of handling well is put into reacting furnace and carry out the heat treatment of 650-820 ℃, the processing time is 10-15 minute;
(5) treated material is carried out to ice water quenching 3-5 minute, at Vacuum Package after annealing 24-48 hour, obtain zirconium gold and silver welding material.
Preferably, described annealing in process is treated to 35 hours.
Beneficial effect: the present invention adopts the method for many alloys, by making it form stable middle phase in alloying process according to different proportion combination in zirconium, gold, silver, tin, thereby the fusing point of this welding material is improved, in addition, the electric conductivity of gained multicomponent alloy welding material is also enhanced.
