Uniform tin coating for oxidation-free copper. Boost solderability, conductivity & RoHS compliance in one final finish step.
The Höllmüller Chemical Tin system by TSK applies an electroless tin plating finish to the copper surfaces of printed circuit boards. A controlled chemical reaction with tin salt solution deposits a uniform tin layer that protects copper from oxidation and corrosion. Precise control of temperature, processing time, and bath concentration ensures consistent layer thickness and quality. The modular design integrates pre-cleaning through final rinse in a single line, enabling easy integration into existing production environments. Manufactured by TÜV SÜD WHG-certified TSK Schill, with wastewater-reducing circuits and low-noise design. World Link LLC provides Japanese-language coordination for installation and after-sales support.
