www.atotech.com ViaKing ® – Revolutionizing flex and rigid PCB manufacturing Primary metallization processes are a key factor in the dynamic world of flexible and rigid printed circuit board production. Carefully designed to maximize process capability and reliability with a low environmental impact, ViaKing ® is MKS' Atotech's state-of-the-art solution for graphite-based direct metallization. Market leading versatility At the heart of the ViaKing process is our unique graphite solution which offers unrivaled bath stability and is compatible with a wide range of dielectric materials for maximum process versatility. Additives within the colloid bath enable high resistance to bac- terial and copper contamination that leads to market-leading bath life, and with a broad process window, Viaking is simple to operate and can be readily installed into existing equipment. Capable of supporting both low and high-volume production, Viaking offers unrivaled flexibility in both panel and pattern plate applications, and the highly conductive deposit enables fast and reliable plating propagation. Optimized for reliability Operating at a low etch depth reduces the risk of etch back- related ICD and void defects, and as the Viaking layer is not present on all copper surfaces, the direct Copper to Copper interface at inner layers and microvias offers the best opp- ortunity for the highest joint reliability. Sustainable solution Being a simple and short process Viaking supports the drive for reduced environmental impact and has low chemical, energy, and water requirements. Further, the chelate-free formulation and the absence of cyanide and formaldehyde also simplify waste management and help you reach and maintain your environmental and health targets. A vision for the future ViaKing represents a major advancement in the flexible and multilayer PCB metallization process. It provides manufacturers with a cost-effective, reliable, and environmentally sustainable solution. With its exceptional performance, its versatility, and its commitment to environmental safety, the process is set to redefine industry standards and drive innovation in the printed circuit board manufacturing industry.
