Graham Johnson, EMEA Product Manager for Parker Veriflo Ultra High Purity Fluoropolymer Valves, looks at the benefits of two point seal valves for semiconductor applications. The corrosive nature of high concentration acids and bases, clear chemistries and slurries used in semiconductor applications mean that pneumatic valves specified for these applications need to be particularly robust.
Parker UHP fittings are designed as leak-free components for applications where ultra-high pure applications are required. MiniButtweld™ fittings provide compact ultra-high pure designs for use with orbital weld equipment. Their unique machining and surface enhancement prevent outgassing and inhibit corrosion.
VacuSeal™ Metal Gasket Face Seal Fittings provide extremely high leak integrity, making them suitable for use in critical applications where ultra-high purity conditions are required, such as semiconductor tool hook-ups, valve manifold boxes (VMBs), and gas distribution systems.
Introducing a new, competitively priced line of metal face seal and weld fittings from Parker, designed for ultra high purity (UHP) semiconductor applications such as manifold boxes, gas cabinets and tool hookup.
A customer that designs cost-effective chemical dispense system contacted Valin for automation assistance. Valin's application engineering and sales team showed the engineers at the company how we could save them money and speed up their delivery time. Lean more.
In Watlow catalogs, brochures and web pages there is a category of controllers listed as “Limits and Alarms”. It is not always clear to everyone when to use these controllers or which type of controller to use. This document is an attempt to clear up some of these issues.
Occasionally questions come up with regard to calibration of Watlow controllers. This paper will attempt to address some of the more common questions on this subject. Many people want to jump in right away and begin performing a calibration procedure before verification. Before you would attempt to calibrate a Watlow controller, verify that the controller is in need of calibration. If you verify that readings of the controller first, you may not have to go through the more involved process of changing the calibration settings.
To comply with the Clean Air Act, a coal-fired power plant needed to heat flue gas to 455°C (850°F). Watlow engineered a customized design that would meet the customer's needs.
Using lean principles in manufacturing is an important element when trying to reduce waste, control costs and ensure timely deliveries to customers. However, this concept of trimming back unnecessary work and reaping the production benefits can also be applied at an individual level in production lines or assembly rooms.
The elimination of air and gases is a great start to be contaminant free, but a vacuum chamber won’t be empty of components when completing an application. You should ensure nothing in the chamber will cause contamination, including the linear mechanics.
A lesson for me is that I need to involve you earlier in the program.
You were tireless in your support and it will not be forgotten!
