Live from ICCG10: The International Conference on Coatings on Glass and Plastics

Posted June 24, 2014 by Dave Christie

This week I’m at the 10th International Conference on Coatings on Glass and Plastics (ICCG10), in Dresden, Germany. This conference is held every two years at various locations in Europe. The locations usually have historic significance as well as intrinsic appeal, and Dresden is no exception with deep history and a legacy of scientific and technical vision and innovation set in the unique beauty of the city through which the peaceful Elbe River winds.

The conference program includes presentations from industry leaders, corporate and government research and development laboratories, and manufacturers of components and systems. I will be giving a talk about our pulsed dual magnetron sputtering (DMS) solutions to improve cost of ownership and productivity with increased control and process monitoring capabilities. One of the points of the paper we wrote for the conference proceedings is the importance of our modular approach to the system designer and end user.

For the system designer, modularity is important, since it provides scalability, with granularity. Modularity for pulsed-DC supplies for DMS can be implemented in two areas: in the DC power section and the pulsing section. The DC power source is implemented as a standalone module. When more power is required, these power sources can be connected together in a master-slave (M/S) configuration to provide the power required for the magnetron pair. The pulsing modules are also implemented as standalone modules with M/S capability. They can be combined to provide the pulsed power required. This modular approach, with power granularity, enables the user to purchase only the power required, and also allows power to be increased in the future by simply adding modules. Power systems can be implemented with powers from 30 kW to 180 kW, with granularity as small as 10 kW. The DC supplies and pulsing modules are rack-mountable, providing tremendous system design, aesthetic, and packaging flexibility. The figure below shows the DMS pulsing module, manufactured by Advanced Energy. Power systems driving adjacent magnetron pairs can be synchronized to prevent crosstalk by using the common exciter (CEX) function. Arc response can also be coordinated with adjacent pairs with additional arc synchronization functionality.

Modularity provides new options for coating system maintenance. Typical power supplies used in large-area coating systems are rated at 100 kW and higher. These typical supplies are too large to ship to a service center for maintenance or repair, and often too complex for the end user to repair. When repair or maintenance is required, it can take time for a service person to arrive at the factory. Now, modular power system components, like the one shown above, can easily be removed and replaced with a spare by the user. Units requiring maintenance and repair are small enough to be easily shipped to a service center, which enables the maintenance group in the factory to self-support with respect to power supply maintenance.
