TL;DR: In this article, a catalyst-imparting liquid is used for conducting electroless reductional palladium plating on a copper-based metal, which enables an even coating film free from thickness unevenness without bridging fine wiring lines.
Patent
Substitution type electroless gold plating liquid
TL;DR: In this paper, a substitution type gold plating liquid with which plating is possible at a practical rate even on an electroless nickel film having a high concentration of phosphorus, and a solder joining applied to the surface of the obtained gold film exhibits sufficient strength even in the case of lead-free type solder.
Patent
Catalyst-imparting liquid for solder plating
TL;DR: In this article, the authors describe a gold-coated solder deposit formed on a copper-based metal and characterized by being obtained by using the catalyst-imparting liquid to conduct electroless reductional solder plating.

TL;DR: In this paper, an electroless gold plating liquid for precipitating a gold coated film on a palladium plated film contains a water soluble gold compound containing no cyano group, a compound represented by general formula (1) or a salt thereof and an electron donative compound having -30 to -700 mV redox potential.
