Perfect smear removal for high-aspect-ratio vias. Optimized for ultra-thin substrates with advanced horizontal transport technology.
The Höllmüller DESMEAR by TSK Schill is a premier horizontal wet chemical system designed for the critical Desmear and Surface Conditioning process in PCB and HDI manufacturing. It is specifically engineered to remove resin residues (smear) generated during laser drilling, ensuring 100% reliability for subsequent plating steps. The system’s advanced fluid dynamics provide intensive chemical exchange even within small, high-aspect-ratio blind vias and through-holes. This uniform treatment ensures superior adhesion for electroless copper, which is vital for high-reliability automotive and server boards. Furthermore, TSK’s specialized horizontal conveyor system is world-renowned for its ability to transport ultra-thin and flexible substrates without damage or tension. Built with a robust 15mm thick polypropylene (PP) structure, the system delivers 24/7 industrial durability in the most aggressive chemical environments.
