By replacing the commonly used sodium cyanide (NaCN) by sodium pyrophosphate (Na4P2O7) in an electroless copper plating bath, the stability and the rate at which copper is deposited are increased. The bath preferably contains copper sulphate, a complexing agent, such as EDTA, a reducing agent, such as formaldehyde, a surfactant and Na4P2O7 .
