    摘要: The present invention relates to a cyanide-free aqueous immersion-type plating bath for deposition of gold, comprising gold ions, at least one complexing agent, sulfite ions, thiosulfate ions, and at least one ureylene polymer additive. The gold layer deposited from the plating bath according to the present invention shows a lemon-yellow colour and a sufficient wettability for tin based solder materials.

    摘要: The present invention relates to a method for manufacture of multilayer printed circuit boards and articles formed thereby, especially IC substrates. The method utilizes a copper-tin alloy layer coated with at least one silane binding agent to provide adhesion between a copper surface and a resin layer after lamination. This method leads to an enhanced adhesive strength, improved mechanical and thermal stress resistance as well as humidity resistance of multilayer printed circuit boards and IC substrates.

    摘要: The present invention concerns an aqueous plating bath composition for electroless deposition of palladium and/or palladium alloys and a method which utilises such aqueous plating bath compositions. The aqueous plating bath comprises a source of palladium ions, a reducing agent, a nitrogenated complexing agent which is free of phosphorous and an organic stabilising agent comprising 1 to 5 phosphonate residues. The aqueous plating bath and the method are particularly useful if the aqueous plating bath comprises copper ions.
