Using Manifold Technology in Fluid Systems for Microelectronics Manufacturing

Optimize Safety, Cleanliness and Cost of Ownership
The management of fluid systems is experiencing a drastic change on how a customer perceives the importance of the component. We have moved from only looking at the component as a standalone item, which has its own specification and benefits for the carried fluid, to looking at the impact of a set of components, which can also be called a manifold on the installation / application. This evolution has been a driving force in the micro-e industry and prompting it to embrace the co-development of products, which is something Saint-Gobain has recognized and supported for years. It is part of our DNA. To review what the manifold approach may bring to your installation/system, let’s split the benefits provided by manifolds into three main categories: Safety, Cleanliness and Cost of ownership.
One of the direct impacts that is inherent when you manifold a set of components is that you are reducing the number of leak points. You are not simply improving the sealing efficiency of a connection; you are totally eliminating it. On average you can expect a leak point reduction above 60%. On some occasions it can be significantly higher than that, but that percentage relates directly to what you are manifolding. As an example, please read our Case Study on Manifold-Based Designs >>
Another advantage related to safety, though less obvious than previously described, derives from the fact that when we are designing these manifolds, we (under our hat of component experts) are able to choose products that have the same level of performance and operating factor. Generally, this specific selection offers longer life time for components as they are installed in proper condition of use.
Following the same logic as above, but this time related to cleanliness, when we design a manifold based on a customer-specific requirement, we also ensure that from a cleanliness and SEMI standard point of view we are using components that belong to the same category. Cleanliness of a system is also directly related to the number of connections that are present in your design, as all connection points are equal to a potential entrapment point regardless of how good a fitting may be or a weld may be. So removing connection points turns your system into a cleaner system even if you are using the best connection system.
