Holm Conference Attendees

Opening: G. Witter

TC-1 of IEEE-CPMT meeting was called to order by Chairman G. Witter.

1. Approval of minutes of previous meeting - G. Witter

2005 meeting minute has been posted at www.ewh.ieee.org/soc/cpmt/tc1/ web page. It was approved. Attendance list was circulated to capture new members, particular emphasis was put on e-mail for easier communication for the IEEE office.

2. Preliminary Report on 52nd IEEE-Holm Conference – Henry Czajkowski

        Total registration is 100 attendee plus 11 registered for the Internsive Course. 47 technical papers, Holm Award Lecture, Mort Antler Lecture and panel discussion .

        Conference sponsor program is working out good to help support the conference.

        Ragnar Holm Scientific Achievement Awardee, Dr. John McBride, Univeristy of Southampton, Southampton, UK “Developments in Fretting Studies Applied to Electrical Contacts”

        The Dr. Morton Antler Invited Lecture was given by Dr. Werner Johler, Tyco Electronics AXICOM, Au-Wadenswil, Switzerland, "The Design Challenges Involved in Miniaturization of Electromechanical Relays"

        Panel discussion by 4 experts on Application and Properties of Nanomaterials in Electrical Contacts”.
1.
Electrical Contacts at the Nanometer Scale, Professor Mark Hersam, Northwestern Univesity
2. Tribological Behavior of Nanostructured Materials and Tribolobical Processes under Light Loads, Professor D. Y. Li, University of Alberta.
3. Nanoscale Carbon materials for Enhanced Thermal and Electrical Interfaces, Professor T. S. Fisher, Purdue University.
4. Passivating Properties of Molecular and Nanoscale Layers, Professor W. Robert Ashurst, Auburn University.

        Visa application for traveler from abroad is still making it difficult for scholars from China to attend in USA

3. Report on 2006 Intensive Course on Electrical Contact - Paul Slade

        After the 2005 Course with 26 students, the suggestion was to have the course immediately after the conference. So this year will be on 9/28-30 at the conference hotel. The feedback from the class is that the industry really needs the class for the young engineers. The 2006 class has 11 registrants.

4. Report on CPMT Transaction –John McBride

        Process for publication in CPMT journal involves reviews in Holm Technical committee by review coordinator with recommendations for CPMT publication. Last year netted 25 recommended papers. The publication limit is around 8 papers, so the editor reviews again and also invited additional referees. By October, the 7-8 authors would be contacted by CPMT about the reviews.

        2004 Holm and ICEC has 9-10 papers published

        2005 Holm papers have 7-8 completed and waiting for publication.

5. World Calendar

        Web link of world calendar events – forward notice to Chi Leung.

6. Publicity – Chi Leung

        Web and CPMT newsletter will be the primary medium for TC1 and Holm information. Many members have used the web for info and registration to conference.

7. International Conference on Electrical Contact ICEC2006:

           Professor Koichio Sawa, reported that the 23rd ICEC at Sendai was a great success.

           Total is 122 abstracts and the distribution as follows: 48 Japan, 20 Germany, 16 China, 8 USA, 6 France, 6 Switzerland, etc.

           Finally 108 papers were included in the proceeding. 66 papers were presented at the technical sessions, and 35 presented in poster sessions.

           239 registered and netted a good financial picture.

           The proceeding in pdf format is also published in CD-ROM..

           23rd International Conference on Electrical Contacts (ICEC) & International Session on Electro-Mechanical Devices 6-9 June 2006, Sendai International Center, Sendai, JAPAN

8. TC1 sub-committee Reports:

        Material restrictions and substitution – Dr. Volker Behrens
ROHS July 2006 has exemptions of AgCdO. All exemptions are to be reviewed in a maximum of 4 years. This is expected to be reviewed as early as 2 years. China and a lot of EU customers are looking for Cd free. Industrial used of AgCdO contacts is till in exemption but customers may select to go Cd free also.

       Automotive – George Drew
Connectors in North America are under tremendous cost pressure. Pb free plating, eliminate solder with compliance pins, mix matching of Au, Ag/Sn, are in tests.

        High Frequency Connectors – Roland Timsit
Hot field, and applied to automobiles. HF connector designers are in shortage. Research work continues to be needed..

        MEMs and micro-contact technology – Bob Malucci
Continues with work shop and a panel discussion with 4 experts in the field.

        High current applications: Arc fault detection and contactors – John Shea and Henry Czajkowski
John Shea reports on Arc Fault Detection
- Arc fault protection has competitive developments in US. New 2008 NEC code change needs AFCI devices. Many different techniques are there to get the job done. Proprietary designs are there to reduce nuisance tripping and size reduction.

Henry Czajkowski reports: Motor Controls
- Business is stable. Material side still has CdO contacts used in large quantities. NEMA products use CdO for performance and cost. Designs are to be smaller and cheaper in a very mature product. Distributed controllers are active, i.e. in motors and not in centralized panels. There are vibration issues. Modular controllers and bus bar system with control and breakers cmounted on. High cost of copper in 2006 is a challenge.

Paul Slade report on High Vacuum Contactors
- 15KV, wind mill applications, contactors for 1000 to 1400A with vacuum contactors doing well.
Adding more functionality and intelligence into contactors; North America still has oversize NEMA designs. Aluminum wire for pole to house is happening because of high cost of copper.

9. New Business –
Pb free story – Dr. Werner Johler, Pb free soldering is at 50% use with no visible impact on reliability.
Copper twisted pair for high data transmission, Fibre to the house, telecommunication relays and RF switching are technologies to keep an eye on.

Respectfully submitted, Chi Leung, 8/2007
