Surface Mount Technology for Sample Systems: Update 2002 “Surface Mount” Definition: Component’s control function is detachable from its flowpath function Providing increased servicability and flexibility while reducing overall space requirements
Surface Mount Technology for Sample Systems: Update 2002 Surface Mount System Options S a m p l e C o n d i t i o n i n g 1) Parker Integrated Conditioning System (PICS) w/ SP 76 compliant 1½” and 2¼” elastomeric seal interfaces & instrumentation components 2) 1½” compliant interface w/ metallic seals and semiconductor grade & instrumentation components (“old” ultra-high purity “standard”) 3) 11/8” interface w/ metallic seals and semiconductor grade & instrumentation components (emerging ultrahigh purity “standard”) 4) R-Max™ stream switching interface (proprietary)
Surface Mount Technology for Sample Systems: Update 2002 SP-76 Interface Standard (Elastomeric) n Roots in semiconductor industry n Geometrically defines device features to match substrate 1½” Interface n Everything above the interface is device supplier specific n Everything below the interface is substrate supplier specific 2¼” Interface
Surface Mount Technology for Sample Systems: Update 2002 Keys to SP-76 Interface Standard n Specifies 1/8” ID flow channels n Liquid service? n System commonly uses diaphragm valves in lieu of ball valves n Geometry specifications do not allow for captured o-rings; housed in counterbore only n Ideal world would incorporate centerline spacing to support captured o-ring design
Surface Mount Technology for Sample Systems: Update 2002 PICS System n Designed w/ 5 flow channels specifically for the majority of sample conditioning systems n Utilizes 1½” SP 76 (o-ring) compliant elastomeric interface n Incorporates larger 2¼” footprint to utilize existing instrumentation devices; SP 76 (o -ring) compliant n Substrate heating capability available w/ minimal
Surface Mount Technology for Sample Systems: Update 2002 PICS System n Substrate assembled via bolts with tapped holes in head n Bolt interface incorporates dowel pin feature for alignment and added rigidity n O-ring connections between substrate blocks
