Winding Webs in Vacuum - including Heat Load
Click HERE to register for this free webinar!

Dr. Charles Bishop
Abstract:

Many of the questions I get asked on the Blog relate to winding problems. A proportion of these are because of film quality issues and the rest are because of heat load problems. This webinar will look at how the film quality can affect winding in vacuum roll coaters as well as what is happening in the deposition zone with the heat load and how this can affect the web and what might be done to improve this aspect of the process.

Process Troubleshooting - Web Technology and Six Sigma Methodology
Click HERE to register for this free webinar!

Dr. Edward Cohen
Mark Miller
Abstract:

Six Sigma is a quality control system utilized around the world for everything from discrete parts to organizational efficiency. The question is: How do you best utilize Six Sigma to reduce web defects and institute process controls? Originally designed for individual parts, Six Sigma methodology requires a unique approach when applied to a continuous web operation. Process troubleshooting in the Six Sigma world hinges on the ability to apply discrete measures to a continuous product. This webinar will walk through the considerations a manufacturing site should go through to reduce product defects and increase robust product design for a continuous web product.

Vacuum Deposit Barrier Coatings

Dr. Charles Bishop
Abstract:

In theory a thin coating of glass or metal should be a perfect barrier but they are not. In this webinar we shall look at the reasons why the coatings contain defects and what might be done to reduce the defects. As the biggest problem is usually that of pinholes and this primarily relates to the quality of the incoming polymer film this will form the basis of the talk.

Troubleshooting - Process/Adhesion/Vacuum
Click HERE to register for this free webinar!

Dr. Charles Bishop
Abstract:

Sooner or later most of us will be presented with a vacuum system, process or product that is no longer working or meeting specification and we will be part of the troubleshooting team who have to correct the problem. It can help to have some structured approach to solving the problem. This webinar is aimed at helping make the troubleshooting process easier by giving a simple process to follow that can be used for any situation. The key first step is to ask questions to make sure that the right problem is being solved. It is all too easy to try to solve the wrong problem because of making assumptions and not confirming the true nature of the problem.

Reactive Deposition by Magnetron Sputtering - The Basic Process and System Design Considerations
Click HERE to register for this free webinar!

Dr. Charles Bishop
Abstract:

The reactive deposition of compounds from metal targets is dominated by the system pumping. Most systems are insufficiently pumped and so there is a hysteresis loop associated with the magnetron sputtering source that needs to be managed and this will be explained. Also the coating uniformity is dependent upon the system design and the reactive process can highlight design flaws such as asymmetry and this too will be explained.
