  • Summary of meeting activities:

    An overview on the history and current activities of committee were presented. The committee continued discussing a proposed new standard practice on cable discharge event and reviewed a current draft. The document is expected to be distributed to all working group members before the September face-to-face meeting.

  • 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.

  • Summary of meeting activities:

    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.

  • 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.

  • 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.

  • 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.

  • 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.

     

  • 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.).

     

  • 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.

     

  • 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.
