At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the critical role of specialized chemicals in advanced manufacturing. Bis-(sodium sulfopropyl)-disulfide, widely known as SPS, stands out as a paramount additive in the realm of printed circuit board (PCB) manufacturing. Its primary function is to ensure high-quality copper deposition, a process fundamental to the functionality and reliability of modern electronic devices.

The intricate nature of PCBs demands precision in every manufacturing step, especially in the copper plating process. SPS acts as a sophisticated brightener and grain refiner, directly influencing the quality of the deposited copper layer. This chemical ensures that the copper plating is not only bright and visually appealing but also exhibits excellent leveling properties. This means the copper deposit is uniform and smooth, even across complex surface topographies often found on PCBs. The improved leveling is crucial for ensuring consistent trace widths and preventing defects.

The conductivity of PCBs is directly tied to the quality of the copper traces. SPS plays a vital role in enhancing this conductivity by promoting a refined grain structure in the copper deposit. A finer grain structure generally leads to lower electrical resistance, ensuring efficient signal transmission. This is critical for the performance of high-speed digital circuits and sensitive electronic components. Manufacturers often seek to buy SPS to guarantee the electrical integrity of their PCBs.

Furthermore, SPS contributes to the overall durability and performance of PCBs by improving the mechanical properties of the copper coating. The deposited copper becomes more ductile, which is important for withstanding the stresses of assembly and operation. This makes SPS an indispensable component in the production of reliable and long-lasting electronic products. The consistent performance of SPS makes it a preferred choice among PCB manufacturers looking for optimal plating results.

The efficacy of SPS is further amplified when used in conjunction with other plating additives. Its compatibility with non-ionic surfactants, polymeric amines, and other sulfur-containing compounds allows for the creation of highly optimized plating baths. These synergistic combinations can lead to further improvements in current density, throwing power, and overall deposit quality, making the plating process more efficient and effective. NINGBO INNO PHARMCHEM CO.,LTD. offers high-purity SPS to support these advanced plating requirements.
