摘要： The present invention is directed to a composition for depositing a palladium coating on an activated copper-coated substrate, the composition comprising:
(i) palladium ions,
(ii) chloride ions,
(iii) ethylenediamine (EDA),
(iv) ethylenediamine disuccinate (EDDS), and
(v) at least one reducing agent,
wherein the composition has a pH in a range from 7.5 to 9.5, preferably from 7.6 to 9.1, more preferably from 7.7 to 8.7, and most preferably from 7.8 to 8.5.
