摘要

根据欧洲议会和欧盟理事会 2011 年 6 月 8 日的指令(也称为 RoHS,即限制在电气和电子设备中使用某些有害物质),对用于生产焊料的合金中铅含量的限制对无铅焊料合金的研究以及焊料生产的经济影响产生了非常积极的影响。它为解决无铅焊料的机械性能和成型焊点的微硬度问题打开了大门,目的是提高无铅焊料的质量并努力降低生产成本。除了生产效率的提高(无需人工清除所谓的焊渣)之外,熔体表面氧化物形成的缓和也是影响锡基焊料无铅合金生产的众多因素之一,这意味着焊料总量的增加。这项工作涉及生产无铅焊料的材料选择问题。当相关元素的浓度发生变化时,温度会影响不同相的形成,因为温度会对焊接产生负面影响。因此,有必要详细了解温度变化时的整个过程。

Tin–Phosphorus Alloy: The Impact of Temperature on Alloy Formation and the Influence of the Dross Amount on the Solder Bath Surface
The restriction of lead content in alloys for the production of solder, based on the Directive of the European Parliament and of the Council of the European Union of 8 June 2011, which is also known as RoHS (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment), had a very positive impact on research into lead-free solder alloys, as well as on the economic impact of the production of solders. It opened the door to issues relating to the mechanical properties of lead-free solders and the microhardness of formed joints, with the aim of increasing their quality and efforts to reduce production costs. In addition to the production efficiency increase, without the need for the manual removal of so-called slagging, the moderation of oxide formation on the melt surface, standing for an increase in the yield of the total amount of solder, represents one of the many factors influencing the production of lead-free alloys for tin-based soldering. This work deals with the issues of material selection for the production of lead-free solders. Temperature affects the formation of different phases when there is a change in the concentration of the elements involved because it can be a negative aspect for soldering. Therefore, it is necessary to have detailed knowledge on the entire process that takes place during temperature changes.
