  • Patent number: 11674235
    Abstract: A method of plating a copper substrate with gold that reduces or eliminates the presence of microvoids at the interface of the gold/copper substrate is described. Suitably, live entry of the substrate into the plating bath is performed with application of external current to the bath such that no portion of the substrate is exposed to the bath for more than one second without the application of the external current. Increase of the applied current for gold strike to the mass-transfer-limit for gold reduction accomplishes the full measure of improvement in eliminating microvoids.
