Abstract
Provided are a welding material and a manufacturing method thereof. The welding material comprises, by mass, antimony 15-20%, zirconium 25-35%, silver 10-20% and the balance yttrium. Due to the fact that the multi-component alloy welding material is manufactured by the antimony, the zirconium, the silver and the yttrium, a melting point reaches to 275-300 DEG C, and a wetting angle formed by the welding material and a base plate is 15-25 degrees, and lead applied to the welding material is replaced on the basis that excellent performance is ensured. In addition, gold is replaced by the silver, the cost of the welding material is greatly reduced, and products can be well popularized.
Description
Technical field
The present invention relates to a kind of welding material and preparation method thereof.
Background technology
Welding procedure is one indispensable technique in electron trade, and in real life, a lot of products are not because the performance of itself goes wrong but eliminated by people because pad comes off.Improve solder technology, research and develop the cardinal task that high performance welding material becomes electronics corporation.Welding material is drawn materials wider, as zirconium, antimony, iron, lead etc.Because lead can be to environment, large to people's healthy harm, leady raw materials is replaced gradually.During welding material work, environment temperature is high, and pad will guarantee to weld smooth, can not affect the performance of electronic component, and people transfer to sight on the raw material of the costlinesses such as gold gradually.Although increase in performance, also greatly increased cost, do not meet inexpensive shopping principle.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of welding material and preparation method thereof.
For solving existing issue, the technical scheme that the present invention takes is: a kind of welding material, comprises the constituent of following content by mass percentage: antimony 15-20%, and zirconium 25-35%, silver-colored 10-20%, remaining is yttrium.
The preparation method of described a kind of welding material, comprises the following steps:
The first step, accurately takes above-mentioned antimony, zirconium, silver and four kinds of raw materials of yttrium, and is encapsulated in the quartz ampoule that vacuum is 4-5KPa, is being filled with helium;
Second step, drops into the above-mentioned raw material of handling well in reactor and carries out melting 18-24 hour for the first time, and temperature is 850-1020 ℃, after interval 10-24 hour, carries out melting for the second time, and melting duration is 10-15 hour, and temperature is 650-850 ℃;
The 3rd step, by the raw material ice quenching-in water after melting, then vacuum-pumping density be honored as a queen in baking oven 100-105 ° annealing in process 48-72 hour welding material.
Preferably: described smelting temperature is for the first time 950 ℃.
Preferably: described annealing in process is 60 hours.
Beneficial effect: prepare multicomponent alloy welding material because the present invention adopts antimony, zirconium, silver and yttrium, fusing point reaches 275-300 ℃ at 15-25 °, has substituted plumbous application in welding material with the angle of wetting of substrate on the good basis of guaranteed performance.In addition, silver has replaced gold to reduce widely the cost of welding material, and product can be promoted better.
