work tests how much loop conductivity and SNR is improved with copper plating
of the silver ink trace. Coils made with
a silver ink base and different amounts of copper plating were compared against
solid copper. This work demonstrates that copper plating of silver ink coils is
possible and it indicates that significant improvements in coil trace
conductivity can be achieved.
Consequently, the SNR performance of silver ink coils that have been
plated with copper improves over silver ink coils without plating.
