  • Meanwhile , fundamental principles about electroless tin plating by reducing agent and disproportionation reaction were explained . function of every component in the bath was explained that complexing agent can effectively change the potential of copper and tin , and accelerate the beginning of replacement reaction favorably ; reducing agent can increase the rate of chemical reaction and has the effect of promoting reaction dynamics too ; antioxidant can effectively prevent sn2 + in the bath from being oxidated ; additive agent a can improve the stability of the bath ; additive agent b has such effects as refining and brightening for the tin deposits , and it enlarges the range of brightening section ; additive agent c used as leveling agent can not only make the depostis level off , but also improve the dispersive ability of the bath ; surface - active agent can solve bubble problem which gathered on the surface of the deposits , and improve the surface quality of the deposits and the bath stability
    阐述了镀液中各组分的作用:络合剂能有效地改变铜、锡的电位,促使初期的置换反应顺利进行;还原剂能加快化学反应速度,对反应动力学有积极的促进作用;抗氧化剂能有效地防止镀液中sn ~ ( 2 + )的氧化;添加剂a能提高镀液的稳定性,添加剂b对镀层能有细化和光亮作用,扩大了镀层光亮区的范围;添加剂c作为平滑剂,不仅能增强镀层表面的平整性,而且能提高镀液的分散能力;表面活性剂较好地解决了化学镀过程中汽泡在镀件表面聚集的问题,提高了镀层的表面质量和镀液的稳定性。
  • When sn2 + concentration in the bath is lower , sn2 + activity is not enough causes slow deposition rate and slow growth rate of crystallizing nucleus , so crystalline granularity deposited is smaller ; when sn2 + concentration in the bath is higher , the dispersive ability of the bath decreases and the surface quality of the deposits sets worse
    镀液中sn ~ ( 2 + )浓度较低时,离子活度不够,沉积速度慢,晶核成长速度慢,使沉积的晶粒粒度较小; sn ~ ( 2 + )浓度过高,镀液分散能力降低,使镀层的表面质量下降。
