摘要：

The influence of potassium ferrocyanide on the electroless copper plating rate and the structure of the deposit is investigated. It is established that, in contrast to free ferrous ions, the ferrocyanide complex, even in low concentrations, reduces the plating rate at room temperature. It is assumed that this behaviour of the ferrocyanide complex is due to the presence in the solution of some free cyanide ions. Good surface levelling is observed in electroless copper plated in solutions containing potassium ferrocyanide. This effect is enhanced by the presence of poly(ethylene glycol).
