ABSTRACT:
The present invention provides an electroless gold plating solution which does not precipitate gold at high concentrations of thallium or lead compound, while retaining its effects such as increased deposition rate and larger crystallite sizes in the deposited layer. The electroless gold plating solution according to the invention contains 0.1-10 g/l of a chelating agent, such as diethylenetriaminetetraacetic acid (DTPA), ethylenediaminetetraacetic acid or nitrilotriacetic acid, DTPA being a preferable agent.
