At NINGBO INNO PHARMCHEM CO.,LTD., we recognize that achieving optimal electroplating results often involves a sophisticated interplay of multiple chemical additives. Sodium 3-(dimethylcarbamothioylsulfanyl)propane-1-sulfonate (DPS, CAS No. 18880-36-9) is a highly effective component, but its performance can be further amplified when used in combination with other complementary chemicals. Understanding these synergistic effects is key to unlocking advanced plating solutions.

DPS is frequently used alongside other sulfur-containing organic compounds that also function as brighteners and levelers in copper electroplating. For instance, compounds like bis(sodium-sulfo-propyl) disulfide (SPS) and 3-mercapto-1-propanesulfonic acid sodium salt (MPS) are often employed in conjunction with DPS. SPS is known for its excellent brightening and leveling capabilities, and when combined with DPS, it can lead to even more refined surface finishes with enhanced ductility. The interplay between these molecules helps to control grain growth and surface morphology more precisely, ensuring that benefits of DPS in automotive plating and semiconductor applications are maximized.

The ability of DPS to be combined with non-ionic surfactants is another crucial aspect. Surfactants play a vital role in reducing surface tension in the plating bath, which can improve wetting of the substrate and lead to more uniform metal deposition, especially in complex geometries or through-holes common in printed circuit boards. When used together, DPS and surfactants can help achieve superior coverage and eliminate plating defects, contributing to the overall goal of improving ductility of copper deposits.

Moreover, the combination of DPS with polyethylene glycols (PEGs) can further enhance the leveling and throwing power of the plating bath. PEGs can modify the adsorption behavior of DPS and other additives, helping to direct the deposition of copper into recessed areas more effectively. This is particularly important in applications where uniform thickness across intricate surfaces is critical, such as in the production of PCBs and microelectronic components.

NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality DPS that is designed for compatibility within sophisticated plating formulations. By understanding and leveraging these synergistic effects, manufacturers can achieve enhanced brightness, improved ductility, better leveling, and overall superior performance in their copper electroplating processes. Our technical expertise is available to assist clients in formulating the most effective plating baths tailored to their specific needs, ensuring they benefit from the combined power of advanced chemical additives.
