Tuesday September18, 2007
4:45 PM
Sheraton Hotel, Pittsburgh, PA

Chair: G. Witter
Vice-Chair: Bob Malucci
Secretary: C. Leung

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

2006 meeting minute has been posted at web page. It was approved.

2. Preliminary Report on 53rd IEEE-Holm Conference – John Shea

        Total registration is 125 attendee from 8 coountries.

        Total of 48 technical papers with contributions from USA 14, Japan 15, China 7, Frnace 5, Germany 2, Austria 2, UK1, Switzerland 1.

        Ragnar Holm Scientific Achievement Awardee, Dr. Ji Gao Zhang, Beijing University of Posts & Telecommunication, “Effect of Dust Contamination on Electrical Contact Failure”

        The Dr. Morton Antler Invited Lecture was given by Professor Hoachim Heberlein, Mechanical Engineering Dept., U. of Minnesota “The Characterization of the Dynamic Arc-Anode Interaction and Using Plasma Deposition of Nanocomposites to Tailor Materials Properties”

        The dinner social on Monday was well attended by 96 including spouses at the Grand Concourse.

        The 2008 IEEE Holm Conference will be in Orlando, 27-29 October.

        Conference feedbacks are very positive considering Pittsburgh to be a good choice

        The technical program is rated strong, with very good printing qualities of the proceedings.

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

        There was no course offered in 2007 but will be offered in 2008 as a 3 day course right before the Holm Conference a the Florida Hotel & Conference Center, Orland FL, with a Sunday break.

        The 2006 course held after the Holm conference was considered not a good time and better to be before the conference.

        Course offered every 2 years is considered a good plan.

4. Report on CPMT Transaction –John McBride

        2006 Holm Papers: 6-7 were recommended by the Technical Committee reviews for CPMT publication. Of the 7, 5 are resubmitted to CPMT review.

        CPMT journal has 18months of backlog of publications.

        IEEE quota is about 6-7 Holm papers per year. However, individuals can also submit directly to CPMT

        CPMT has a page limit per issue, and that is the reason for not able to publish quickly.

        TC1 will work with CPMT to accept more papers and faster publication

5. World Calendar

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

        2007 ICREPEC (International Conference on Reliability of Electrical Products and Electrical Contacts) was held in March 2007 in Xiamen, China. The conference included plant tours to HongFa Relay and ABB Xiamen Switchgear.

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 ICEC2008 – Professor Ben Jemaa, Conference Chair:

           24th ICEC will be in St. Malo, France, 9-12 June 2008. St. Maol is about 300 km form Paris with Plane/train easy access. It is an old city with about 80,000 population and a lot of historic attractions close by.

           Many IEEE conferences had been held at the Conference Center

           200 rooms have been reserved in near by hotels

           Send abstracts by mid November

           IEEE France section is also co-sponsor.

8. IEICE Tranaction – Professor Makoto Hasegawa, Chitose Institute of Science & Technology

           IEICE Transaction (Institute of Electronics, Information and Communication Engineers) has special issues on electromechanical devices

           50 papers from the 2006 ICEC at Sendai can be submitted

           Contact for paper submission details

8. TC1 sub-committee Reports:

        Material restrictions and substitution – Dr. Volker Behrens
ROHS in consumer products – expect the Cd exemption will run out in 2-3 years. Discussions in European Union to add other exemptions but not likely to change. Next 2 years, Cd use is ok. Market in AgCdO is decreasing substantially in Europe and replaced by various Cd free contact materials. As AgCdO quantities decreases, expect price to go up. Japan does not use AgCdO. All AgCdO material made in Japan are for exports. Tanaka has cancelled production of AgCdO in Japan. Pb free: some exemptions allowed by EU.
Henry Czajkowski : NEMA is taking a proactive approach while some states try to adopt ROHS regulations. NEMA new strategic initiative is to influence legislative to be uniform and not as restrictive. Nickel ban is not an issue. Pb free tin plating has issues with tin whiskers. CA has adoption same as EU, China is process to be similar to EU.

        High Frequency Connectors – Roland Timsit
Not much new break through since 2 years ago, with incremental changes to 2 GHz; copper wire still in use because skin depth losses are small and rebuilt signals before use is not dead; optical fibre is now in the back seat again.

       MEMs and micro-contact technology – Bob Malucci
Increased interest with MEM and NANO in this conference.
Carbon Nano Tube is more of same. We need to actively solicit papers while MEMs tend to go to the IEEE MEM’s conference.

        Motor Controls Technology - Henry Czajkowski
Trends are miniaturization and bus bar systems; high performance demands on contactors; distributed controls, more harsh environments, vibrations and clean. Standards: UL and CSA trends to harmonize with IEC standards. 6947-4-1 is published but not very useable yet. But further works to squeeze out differences. NEC codes are new on spacing, utilization etc. Traditional NEMA products are all AgCdO. Designs for new NEMA and IEC may go Cd free. ROHS requirements are for consumer products.

        High current applications: Arc fault detection John Shea
There is an AFCI session in this conference. Work on series arcs continue. New AFCI products Jan 2008 are mandatory. NEC new home construction and retrofit require detection of low level parallel and undesirable series arcs. Soon to be whole house circuits with 15A and 20A not for appliances. A lot of proprietary work. Cost differential is $32 AFCI breakers vs traditional $5 circuit breakers. Each state has to adopt the NEC code. Electronic detection and arc physics knowledge required for design. Other countries UK at higher voltages need more studies.

        Telecommunication – Werner Johler
Challenge is material price increases of all components including Cu, Fe, precious metals, plastic and energy
No breakthrough in MEMs due to high costs and characteristics (isolation, load switching, reliability). This maintains the opportunities for electromechanical devices.
Recent requirements for telecoms are 6 kv isolation, coil/contact, and 3.5kv between open contacts
Ultra-minimization UL508 requirements are good isolation materials. No material available to meet all requirements, head ache to relays manufacturers.

Respectfully submitted, Chi Leung, 8/2008
