    摘要: The present invention relates to an aqueous composition for and a process for etching copper and copper alloys applying said aqueous composition. The aqueous composition comprises a source for Fe 3+ ions, at least one acid, at least one triazole or tetrazole derivative, and at least one etching additive selected from N-alkylated iminodipropionic acid, salts thereof, modified polyglycol ethers and quaternary ureylene polymers. The aqueous composition is particularly useful for making of fine structures in the manufacture of printed circuit boards, IC substrates and the like.

    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.
