59th IEEE Holm Conference on Electrical Contacts
22-25 September 2012

Hotel Viking, Newport, RI
Sponsored By:
The Components, Packaging, and Manufacturing Technology Society of the IEEE

Purpose:
To provide a forum for the presentation and discussion of the latest developments in the field of electric contacts including research on materials, contact and connector designs, and the applications of these designs in electric, electronic and telecommunication equipment.

For Whom:

Practicing designers, engineers, physicists and research scientists - those new to the field and those experienced.

The 2013 Holm Conference will include a proceeding given out at the beginning of the conference with more than 57 presentations by US and international engineers and scientists. This provides an opportunity to study papers of interest before the actual presentation and promote better question and answer discussion during the conference.  These papers and discussions of the papers provide the attendees with an up to date look at the research being done in the contact field.


Additionally, the conference provides a forum that allows attendees to meet and personally discuss the work of different authors and experts in the contact field.  These exchanges provide a synergistic environment for further advancements in the electrical contact field.
