摘要
研究了等温时效对 SnAg/Cu表面贴装焊点微结构, Sn-Cu金属间化合物生长及其剪切强度的影响,并与常用的62Sn36Pb2Ag/Cu焊点进行了比较,结果表明,在时效过程中, SnAg钎料以较小的反应速率与 Cu发生反应 SnAg焊点显示了较强的剪切强度并且其受时效的影响较
The effect of aging on the microstructure and shear strength of SnAg/Cu surface mount solder joint was investigated with comparison to 62Sn36Pb2Ag/Cu. It was found that the reaction rate between SnAg and Cu is smaller compared with SnPbAg and the shear strength of SnAg solder joint is higher and not so sensitive to the aging process.
