Abstract

Electroless copper plating baths include alternative reducing agents to the conventional reducing agents currently used in the electroless plating industry. The electroless copper baths are stable and deposit a salmon bright copper deposit on substrates. Exclusion of many environmentally unfriendly conventional reducing agents enables environmentally friendly electroless copper plating baths.
