Fabrication




   Fabrication:       
   Your choices are...
 
      
 
   Conventional Construction
 
     A service to provide permanent constructed cleanrooms.
 
   Modular Hardwall
 
     Modular cleanrooms are constructed on site from pre-cut and assembled components, such as walls, ceiling grid struts and other components.  The walls of the cleanroom are of a solid material, rather than fabric.  Hardwall cleanrooms provide the rigidity and durability of a freestanding room.
 
   Modular Softwall
 
     Modular cleanrooms are constructed on site from pre-cut and assembled components, such as walls, ceiling grid struts and other components.  The walls of the cleanroom are constructed from fabric, either of free-hanging strips or stretched tightly over a frame.
 
   Mini Environment
 
     A localized clean environment utilized in semiconductor applications created around a tool, or only within a tool where wafers will be exposed to the atmosphere. Wafers are moved from one mini environment equipped tool to the next mini environment equipped tool in sealed containers and only exposed to the atmosphere inside of the clean environment created inside the tool.
 
   Micro Environment
 
     A very small, localized clean environment utilized in semiconductor applications created around a tool, or only within a tool where wafers will be exposed to the atmosphere.
 
   Other
 
     Other unlisted fabrication design.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Cleanliness Class




   Cleanliness Class:      The contamination control industry currently uses a government specification known as Federal Standard 209D to provide a qualified and standardized method for measuring how clean the air is in a cleanroom. Six classes have been established to designate cleanroom cleanliness.

The class number refers to the maximum number of particles bigger than one-half of a micron that would be allowed in one cubic foot of cleanroom air. A Class 100 cleanroom, for example, would not contain more than 100 particles bigger than half a micron in a cubic foot of air.
   Your choices are...
 
      
 
   Class 1 (ISO 3)
 
     A cleanroom where particle count is not to exceed a total of 1 particle, 5 microns or larger in size, in a cubic foot of air.
 
   Class 10 (ISO 4)
 
     A cleanroom where particle count is not to exceed a total of 10 particles, 5 microns or larger in size, in a cubic foot of air.
 
   Class 100 (ISO 5)
 
     Particle count not to exceed a total of 100 particles per cubic foot of a size 0.5 micron and larger.
 
   Class 1,000  (ISO 6)
 
     A cleanroom where particle count is not to exceed a total of 1,000 particles, 5 microns or larger in size, in a cubic foot of air.
 
   Class 10,000 (ISO 7)
 
     Particle count not to exceed a total of 10,000 particles per cubic foot of a size 0.5 micron and larger, or 65 particles per cubic foot of a size 5.0 micron and larger.
 
   Class 100,000 (ISO 8)
 
     Particle count not to exceed a total of 100,000 particles per cubic foot of a size 0.5 micron and larger, or 700 particles per cubic foot of a size 5.0 micron and larger.
 
   Other
 
     Other unlisted cleanliness class, examples include ISO 1, 2 and 9.

Features and Options




   Panel / Wall Material:       
   Your choices are...
 
      
 
   Steel
 
     A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
 
   Steel - Stainless
 
     Stainless steel is chemical and corrosion resistant and can have relatively high-pressure ratings.
 
   Acrylic
 
     A thermoplastic with good weather resistance, shatter resistance, and optical clarity.
 
   Aluminum
 
     A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
 
   Composite
 
     A solid material comprised of two or more substances that have distinct properties. When merged, each substance retains its own characteristics while imparting the entire composition with beneficial properties. For example, a plastic material in which a fibrous framework is embedded for greater structural stability.
 
   Fabric
 
     A cloth, or material that resembles cloth.
 
   Fiberglass (FRP)
 
     Fiberglass reinforced panels.  Strong, durable, and impervious to many caustics and extreme temperatures; fiberglass fabrics are widely used in industry.
 
   Glass
 
     Glass has optical, mechanical, and thermal properties and has been a major building component for centuries.
 
   Polycarbonate (PC)
 
     Polycarbonate is an amorphous material with excellent impact strength, clarity, and optical properties. Polycarbonate has excellent mechanical properties, and can be molded to tight tolerances. However, solvents and petrochemicals corrode it, and its weather resistance is merely adequate. Brand Names include: Caliber® (Dow), Lexan® (GE), Makrofol® and Makrolon® (Bayer).
 
   Polyethylene Film (Shrink-wrap)
 
     A very thin layer of polyethylene.  Polyethylene is a semi-crystalline (typically around 50%), whitish, semi-opaque commodity thermoplastic that is soft, flexible and tough - even at low temperatures - with outstanding electrical properties but poor temperature resistance. It also has very good chemical resistance but is prone to environmental stress cracking; it has poor UV resistance (unless modified) and poor barrier properties, except to water.
 
   PVC
 
     Polyvinyl Chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex).
 
   Vinyl
 
     Vinyl exhibits good flexibility and chemical resistance; it is used in many medical and chemical applications.
 
   Other
 
     Unlisted, specialized, or proprietary material.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   ESD Control:      The cleanroom has measures to control the rapid, spontaneous and usually uncontrolled transfer of an electrical charge between two conductors induced by a strong electrostatic field.
   Your choices are...
 
      
 
   Static Dissipative
 
     The panels of the cleanroom are less susceptible to triboelectric charging.
 
   Conductive Panels
 
     The panels of the cleanroom are coated with a conductive epoxy or paint.
 
   Low Outgassing
 
     The panels of the cleanroom outgas low amounts of particles.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Air Shower?
 
     Chambers located between the cleanroom and an outside environment that remove particulate contamination from cleanroom garments as personnel pass through. The chambers may include HEPA filters, interlocking doors, a recirculating air system, and air nozzles in various patterns through which filtered air is blown onto the personnel in the shower. The air is moved over the worker, removing particulate contamination from the worker's garments.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Product / Tool Pass Through?
 
     Openings in walls with two doors through which materials and objects are passed. Pass through doors interlock so that one door always is closed while the other is open.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Gowning Area?
 
     Area designed to be used for dressing into cleanroom garments.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
