Abstract

The invention relates in general to a method of electroplating substrates where at least a portion of the substrate is coated with a solution containing a flhn forming amine and sufficient acid to produce a pH of less than 6.5. The acid helps to clean the surface of the substrate, and the film forming amine forms a film on the surface of the substrate. Electroplating proceeds with greatly improved speed and efficiency, especially in low current areas.

1. 1. A method of electroplating a substrate comprising: providing a solution comprising from about 0.0003% to about 30% of a film forming amine and sufficient acid to produce a pH of less than about 6.5; and coating at least a portion of the substrate with the solution, thereby forming a film on the substrate; and plating the substrate.
