SEMI International Standards
SEMI New Activity Report Form (SNARF)



Activity Number: 5595
SNARF for: New Standard: Guide for the Development of Dimensional Standards for “Sandwich” Surface Mount Components


Originating Global Technical Committee: Gases
Originating Technical Committee Region: North America
Task Force in which work is to be carried out: Surface Mount Sandwich Component Dimensions Task Force


1. Rationale: Surface mount sandwich components (filters, check valves, restrictors, port converters) do not have dimensional standards and vary from manufacturer to manufacturer. This creates interchangeability issues between manufacturers of functionally equivalent components.
Rate the Estimated Effect on the Industry
2: Major effect on an industry sector - identify the relevant sector

Rate the Estimated Technical Difficulty of the Activity
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Define the areas to be covered or addressed by this activity or document:
Develop a thickness dimension standard for surface mount sandwich component thickness.

b: Expected result of activity
New Standard

3. Projected Timetable for Completion:
a: General Milestones
a. Activity Start: 07/01/2013b. 1st Draft by: 11/01/2013
c. Preballot by: d. Technical Ballot by: 04/01/2014
e. Committee Approval By:07/01/2014




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


Intellectual Property Considerations:
a. In complying with the standard or safety guideline to be developed, the use of patented technology or a copyrighted item(s) is NOT required
b. The body of the standard and any appendices or related information sections will NOT include copyrighted material

Comments, Special Circumstances: None.

Approval: Activity approved by Committee/GCS on April 29, 2013
