2. 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

3. Surface Mount Technology for Sample Systems: Update 2002 Surface Mount System Options 1) Parker Integrated Conditioning System (PICS) w/ SP76 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) 1 1 / 8 ” interface w/ metallic seals and semiconductor grade & instrumentation components (emerging ultra- high purity “standard”) 4) R-Max™ stream switching interface (proprietary) SampleSampleSampleSample ConditioningConditioningConditioningConditioning

4. SP-76 Interface Standard (Elastomeric) n Roots in semiconductor industry n Geometrically defines device features to match substrate n Everything above the interface is device supplier specific n Everything below the interface is substrate supplier specific Surface Mount Technology for Sample Systems: Update 2002 1½” Interface 2¼” Interface

5. 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 Surface Mount Technology for Sample Systems: Update 2002 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

6. PICS System n Designed w/ 5 flow channels specifically for the majority of sample conditioning systems n Utilizes 1½” SP76 (o-ring) compliant elastomeric interface n Incorporates larger 2¼” footprint to utilize existing instrumentation devices; SP76 (o-ring) compliant n Substrate heating capability available w/ minimal development Surface Mount Technology for Sample Systems: Update 2002
