Documents:

Working Group Chair:  Thomas Meuse, Thermo Fisher Scientific

 

Summer 2018 Virtual Meeting

Agenda items for the meeting on June 19, 12:15 – 1:45 PM EDT are:

  1. Review of Meeting Etiquette and Policies (5 minutes)
  2. Brief summary of WG activities (no longer than 10 minutes)
  3. Discuss writing and article of CDE for In Compliance Hot Topics – volunteers?
  4. CDE document review – writing team to use this time to review document and propose section changes

 


April 2018 Face-to-Face

Summary of meeting activities:
The committee discussed a proposed new standard practice on cable discharge event and reviewed a current draft. Further discussion will be held at the June virtual meeting. The group also discussed the development of a TR to highlight all the data that was collected for CBE over the years.

Agenda items for the meeting on April 15, 8:00 – 10:00 AM PT are:

  1. CDE SP and Data TR review
  2. Next steps in WG 14 (please think about this before the meeting)
  3. Other business

Winter 2018 Virtual Meeting
A history of the working group was presented to attendees; which elicited some good questions. The group reviewed the new proposed cable discharge event document and discussed the development of a technical report highlighting previous data


Summer 2017 Virtual Meeting
Summary of meeting activities
A presentation was given on “How can ESD compliance to HBM, CDM requirements below 100 volts be proven in a production area?” The presentation showed some of the issues seen in a factory, relating to grounding, CDE, and CBE type events. The presentation was focused on more than CDE and went into other areas resulting in a number of questions. A new standard practice addressing CDE was proposed and a writing team was formed.

Agenda items for the meeting on July 19, 2017, 11:30 AM – 1:00 PM ET are:
a.      Review of the charged device event document
b.      Schedule next actions for the charged device event document
c.      Any Other Business


April 2017 Face-to-Face Meeting
Summary of meeting activities
A presentation was given on “How can ESD compliance to HBM, CDM requirements below 100 volts be proven in a production area?” The presentation showed some of the issues seen in a factory, relating to grounding, cable discharge event (CDE), and charged board event (CBE) type events. The committee discussed CDE and the development of a CDE document. Data gathering will begin which can be used for a TR on USB data, Ethernet data, and other cables. The measurement techniques used here, may be used for capturing info from other cable types – automotive, avionics, military.

Agenda items for the meeting on April 30, 2017, 8:00 – 10:00 AM MT are:
a.      Introduction
b.      Updates on CDE testing / document
c.      Any other business


Winter 2017 Virtual Meeting
Summary of meeting activities

An overview of the WG history and highlights of current activities was presented. An update was given on the status of articles being written to promote ANSI/ESD SP14.5, Scanning. A draft article has been written but additional real device data is required (data that can be presented) to complete the article. The working group discussed how to move forward in writing a technical report on the different possible charged board events. It was determined that it would be best to compile data before trying to write a standard practice for the method.

Agenda items for the meeting on Wednesday, February 1, 2017, 10:00 – 11:30 AM ET are:
a.      Introduction
b.      Updates on CDE testing / document
c.      Any other business
d.      Schedule review


September 2016 Face-to-Face Meeting
Summary of meeting activities

The working group discussed an article being written for EDN, a publication that focuses on EMC scanning. The article will discuss case studies demonstrating what the new method in ANSI/ESD SP14.5 can provide the user. The committee also discussed the status of a document on cable discharge event (CDE). A sub-group has been formed to create a test setup / overview of the method that will be used as the basis for new data collection. Once measurement techniques are defined, data will be captured leading to the development of a standard practice.

September 10, 2016, 8 -  10 am PDT meeting agenda items:

  • Update on the Articles on EMC Scanning
  • CDE discussions
    • Review of previously collected data
    • Develop list of additional data requirements  
    • Recommendations for standard development
    • Presentations on recent System Level activities (if any)
    • Discussion: future work of WG 14

Summer 2016 Virtual Meeting

Summary of meeting activities
The committee discussed articles being written for EDN to help promote the scanning technique outlined in ANSI/ESD SP14.5-2015. An outline has been provided to EDN and a sub-team will be working to finalize the article. The sub-team will also review if a technical report should be written that goes deeper into some of the scanning techniques. A discussion was held on the status of the document on cable discharge events (CDE). The original plan to merge two documents into one has been expanded to include conditions where damage can occur due to cable discharge events (i.e. USB cable, USB cable connected to peripheral device, different Ethernet lengths, etc.).

Thursday, July 14, 10:00 – 11:00 am meeting agenda items:

  1. Welcome
  2. Introduction to activities of WG 14 – history and document
  3. Standard Practice SP 14.5-2015 “Near-Field Immunity Scanning – Component/Module/PCB Level”: Moving this to Industry

        Update on technical report / magazine article development  

  1. CDE Document – status

        Gathering of previous data

        Outline development

  1. Presentations on recent System Level activities (if any)
  2. Discussion: future work of WG 14

April 2016 Face-to-Face Meeting
Summary of meeting activities
The committee discussed the overall cable discharge event (CDE) document based on concerns raised by members during another committee meeting. Concerns include: Is the calibration target correct? Is the document really addressing the need? Should we change the focus and understand the real world events, before defining the standard? A decision was made to compile all previous data and new data being collected in transient latch-up field, review the data, and move forward with a rewrite of the current CDE document.

The WG also continued a discussion regarding the dissemination of ANSI/ESD SP14.5 (EMC Scanning) to industry users.

Agenda
Sunday, April 17, 8-10 am meeting agenda items:

a.  Progress of developing information to get the EMC scanning document out to industry


Winter 2016 Virtual Meeting
Summary of meeting activities
The committee discussed industry outreach strategies for awareness of test method in ANSI/ESDSP14.5-2015. A subcommittee has been formed to develop a technical report or articles promoting thescanning technique in ANSI/ESD SP14.5. The committee reviewed the current status of the cable discharge event (CDE) document.
