Pre-treatment & Activation

Standard Activation

Neoganth® E Activator System

  • The Neoganth® E activator system has been specifically designed to operate at a minimal Pd content with excellent coverage performance. Achieving a high activator bath stability dramatically reduces Pd precipitation and sludge formation, ensuring that Pd loss is kept to a minimum, but more importantly, the Pd remains in solution where it needs to be to ensure excellent dielectric and glass coverage. Suitable for all horizontal applications where cost control is critical, the Neoganth® E Activator system is ideally suited for low and high volume PCB production

Direct plating

Propagation test for Viaking

  • ViaKing® is a cost effective, enhanced graphite metallization process ideally suited for flex, flex rigid and multilayer PCBs using exotic or mixed dielectric materials. Designed to accommodate a low etch rate, in combination with a graphite step that can operate at a higher temperature and pH, ViaKing® provides excellent stability, conductivity and electrical integrity for market leading high yield electrolytic plating.
  • Ecopact® CP is a well-established conductive polymer based direct metallization process that is suitable for both vertical and horizontal application. It is environmental friendly because of low consumption and waste water generation and no use of harmful substances like cyanide or formaldehyde. Thus, Ecopact® CP is often considered as the “green” alternative to electroless copper processes for HDI, MLB and Flex-Rigid production.
  • Neopact®: Neopact® is an organic-stabilized and palladium based technology. It has an unparalleled ability to adhere to almost any type of base material. Even on Teflon, Neopact® achieves excellent plating results. This makes it the ideal choice for HDI, MLB and flex applications with “exotic” laminates. The easy to handle process is based on environmental friendly chemistry making Neopact® a future oriented alternative to the classical electroless copper process. It is applicable in horizontal and vertical mode.

Desmear
direct plating desmear

Ajinomoto bare laminate: Prior and after desmear (magn. 1000x)

  • CupraTech® TS and TeloTech® TS Black – Metallization of Touch Sensors based on Copper Mesh: ITO (Indium-Tin-Oxide) based transparent conductive films are the state of the art technology that is applied in most touch sensors manufactured worldwide. Recently, several competing technologies emerge to enable flexible and large size touch sensors – not possible with the ITO based technology. Atotech is providing chemical solutions for one of the most promising technologies based on copper mesh as conductive layer. CupraTech® TS is enabling electroless copper deposition on seed different seed layer whereas TeloTech TS Black is minimizing the visual perception of conductor tracks on substrates.
  • CupraTech® FPD – Metallization of Flat Panel Displays: The contemporary metallization technique for the thin-film-transistor (TFT) in liquid-crystal-displays (LCD) is classical copper sputtering. Atotech offers solutions to replace copper sputtering by electroless copper deposition and therefore overcome several disadvantages of copper sputtering like the stress transfer of the sputtered copper to the glass substrate resulting in high warpage and the risk of glass breakage. In addition, electroless copper is capable of plating thick copper layers that might become a requirement for the next generations of flat panel displays in order to ensure sufficient conductivity of the copper structures. CupraTech® FPD is a high speed electroless copper process enabling excellent surface distribution and low surface roughness performance – both key requirements for this application. Atotech supplies not only chemistry but also high-tech horizontal conveyorized equipment adapted to the requirements of the flat panel display industry especially to the transportation of thin and large size glass panels. Using our dedicated VisioPlate equipment enables FPD manufacturers to achieve the best possible technical performance while mitigating the environmental impact.
