Tuesday September 26, 2006
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
· 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
The Dr. Morton Antler Invited Lecture was given by Dr. Werner Johler, Tyco Electronics AXICOM,
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.
application for traveler from abroad is still making it difficult for scholars
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
Total is 122 abstracts
and the distribution as follows: 48
· 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..
8. TC1 sub-committee Reports:
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.
– George Drew
· 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.
current applications: Arc fault detection and contactors – John Shea and
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.
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.
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;
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.
