Copper sulfate plating additive for high aspect ratio substrates for package substrates "Topluchina HLS"
This is the latest plating technology for semiconductor package substrates (IC substrates). Currently, electronic devices such as smartphones, computers, and servers are becoming more high-performance, leading to a reduction in the diameter of through-holes that electrically connect the layers of printed circuit boards, as well as a decrease in pitch. As a result, there is an advancement in the high aspect ratio and high density of through-holes. We have newly developed a copper sulfate plating additive for high aspect ratio substrates that can accommodate both soluble and insoluble anodes, aimed at improving the productivity and quality stability of printed circuit board production. This product excels in depositability within through-holes and vias, achieving high throwing power across a wide range of current densities.
