【摘要】 为保护环境所制定的法规以及电子元器件特殊或苛刻的服役条件对钎料性能的要求已成为促进新型钎料合金研制的主要动力,而低成本、高性能又是新型钎料合金应具备的特点.本文就目前国内外钎料合金的无毒化、低成本、高性能、高可靠性以及低熔性、非晶态等发展状况作了介绍、并对现有钎料设计方法以及钎料设计由试验向具有性能预测功能的计算设计方法的发展趋势加以叙述.更多还原

【Abstract】 Strict laws to meet the demands of environmental protection and special or harsh service condition requirements for electronic components to solder properties have been providing main impetus for new solder alloy development.However,it is necessary for new solder alloys to possess the characters of both low cost and high properties.In this thesis,developments of solder alloys in the world such as no poison,low cost,high property,high reliability,low melt temperature and amorphous state are introduced. Moreover,available methods of solder alloy design and tendency of test method turning to calculation method with predictable function in solder alloy design are also elaborated.更多还原
