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
闡述了鍍液中各組分的作用：絡合劑能有效地改變銅、錫的電位，促使初期的置換反應順利進行；還原劑能加快化學反應速度，對反應動力學有積極的促進作用；抗氧化劑能有效地防止鍍液中sn ~ （ 2 + ）的氧化；添加劑a能提高鍍液的穩定性，添加劑b對鍍層能有細化和光亮作用，擴大了鍍層光亮區的范圍；添加劑c作為平滑劑，不僅能增強鍍層表面的平整性，而且能提高鍍液的分散能力；表面活性劑較好地解決了化學鍍過程中汽泡在鍍件表面聚集的問題，提高了鍍層的表面質量和鍍液的穩定性。 -
