SEMI F93 - Specification for Dimension of One Port Components for 1.5 Inch Type Four Fastener Configuration Surface Mount Gas Distribution Systems
This Standard was technically approved by the global Gases Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on August 30, 2012. Available at www.semiviews.org and www.semi.org in October 2012; originally published March 2004; previously published March 2012.
This Standard establishes the properties and physical dimensions of one port components for 1.5 inch type surface mount gas distribution systems.
This Standard includes common requirements, layout, size, detailed specifications, and dimensions of the components.
This Standard applies to one-port/four-fastener components. The components are mounted on substrates with fasteners accessible from the top.
This Standard only applies to components for systems, which control flow of ≤50 slm nitrogen equivalent at 308 kPa (44.7 psia). This Standard also only applies to components with operating pressures less than 3445 kPa (500 psia) at 20°C.
