Standards New Activity Report Form (SNARF)
Date Prepared: 05/18/2010Revised (if Applicable):

Document Number: 4982
SNARF for: New Standard: Mechanical Interface Specification for 450mm FOSB Load Port

Originating Global Technical Committee: Physical Interfaces & Carriers
Originating TC Chapter: North America
Task Force (TF) in which work is to be carried out: International 450 mm Physical Interfaces & Carriers
Note: If a new task force is needed, also submit a task force organization form (TFOF)

___________________________________________________________________________
1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
The International 450mm Shipping Box Task Force (450 ISB TF) responsible for the development of the 450mm FOSB standard has decided that the FOSB door closing force required is 390N and the clamping force associated with it is 190N per clamp feature both of which are excessive compared to the FOUP and MAC closing and clamping forces, such that the FOSB cannot be accommodated in the same load port standard and needs to have its own standard per the agreement in the IPIC TF.

Additionally the force requirements are specified in the carrier standards, thus to avoid confusion and reduce risk for load port standard, 450 IPIC TF has decided it is best to address the needs for the FOSB in a separate document.



b. Estimate effect on industry.
4: Slight effect or effect not determinable
Sector or Company Information:

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:
Develop a Load Port standard that is built on the 450mm FOUP Load Port standard (E154) with the following items as the only requirement difference:
1. Door Closing Force which is specified in the 450mm FOSB ballot
2. Clamping force which is specified in the 450mm FOSB ballot


b: Expected result of activity
New Standard

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 14.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

6. Intellectual Property Considerations:
a. For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines:
the use of patented technology or a copyrighted item(s) is NOT required

If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:


b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):


c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:
will NOT include copyrighted material



NOTE FOR "the use of patented technology or a copyrighted item(s) is NOT required": If in the course of developing the document, it is determined that patented technology or copyrighted item(s) must be used to comply with the standard or safety guideline, the provisions of Section 15 of the Regulations must be followed.)

NOTE FOR "will include reproduced copyrighted material": A copyright release letter must be obtained from the copyright owner.

7. Comments, Special Circumstances:
Intellectual Property Considerations:
Patent and/or patent applications material to this Standards draft document is unknown. Once the task force has determined that there is no alternative to the use of patented technology or copyrighted item(s), this SNARF will be revised then reapproved by the committee and the Global Coordinating Subcommittee (GCS).
