Catalyst solutions useful in activating substrates for subsequent plating |
摘要 |
An improved colloidal activator is disclosed which is useful in preparing substrates for plating. The activator comprises a source of gold, a source of tin and an organic sulfonic acid. Relatively low levels of palladium have been found to be synergistically advantageous. In addition, sulfonated surfactants have also proven to be useful. The colloidal activator may also include colloid stabilizers. A method for preparing and a process for using the activator are also disclosed.
