Look to Atlas Technologies for Bimetallic Bonding

Adhering to UHV standards in cryogenic applications with stainless steel is a process with which many manufacturers are familiar. Most, however, aren’t experienced or qualified to apply those same standards to cryogenic applications when it comes to bimetal solutions; most often involving aluminum. Since the closing of Bi-Braze, increasing numbers of customers have looked to … Continued

Customer Highlight: Dynavac

Our customers at Dynavac are crucial participants in a compelling project for NASA’s Magnetospheric Multiscale Mission at the Goddard Space Center.

Next Generation Vacuum Systems: Aluminum

Published in Solid State Technologies, May 1998, Page 79 Introduction: Written by: Richard Bothell and Justin Bothell, Atlas Technologies; Glen Tisdale, Judith Offerle, UHV Aluminum Company 300mm wafers with Achieving sub-micron feature sizes on a production basis requires an understanding of the complete processing environment including the vacuum reactor itself. Molecular level chemical contamination will … Continued

Reduce Carbon Deposition: Synchrotron and Semiconductor Lithography Optics

Out gassed carbon from stainless steel can be a serious source of contamination and can damage synchrotron optics as well as deep Ultra Violet (DUV) and Extreme Ultra Violet (EUV) optics for semiconductor lithography. We are finding that many of these high profile labs are eliminating any potential carbon from stainless by using aluminum vacuum … Continued

Standard Line of Bimetallic Transition Couplings

Atlas Technologies Introduces Standard Line of Robust Bimetallic Transition Couplings Standard sized aluminum to stainless bimetallic transitions allow aluminum tube or pipe to be welded directly to stainless steel tube or pipe Atlas bimetallic couplings allow for a clean no-flange transition from aluminum to stainless steel tubes or pipe lines. These joints are highly reliable and … Continued

Aluminum’s Extreme Vacuum Performance

Aluminum’s Extreme Vacuum Performance Any single physical or chemical property of aluminum may be enough reason to select aluminum as a vacuum chamber choice over stainless steel. But when looked at in summary, aluminum overwhelmingly surpasses stainless steel as providing the lowest cost of ownership. Aluminum has seven orders of magnitude less hydrogen than stainless … Continued

The ATCR Fitting – a superior gas delivery system

The Atlas ATCR™ Fitting – the aluminum tube fitting with a stainless steel face-seal offers a superior gas delivery system to cryogenic and semiconductor industries Industry leaders are taking advantage of the extensive benefits of aluminum in UHV to improve the performance of their most challenging applications in the fields of cryogenics, aerospace, physics, and semiconductors. … Continued

Titanium Sublimation Pumps

Atlas aluminum “TSP”s outperform their stainless steel counterparts due, in part, to the material’s very low hydrogen permeation—seven orders of magnitude less than stainless steel. Atlas creates a high surface vacuum environment for condensation of the Ti pumping film without producing hydrogen. Stainless steel, on the other hand, desorbs hydrogen. A 42” wire seal chamber … Continued
