The second annual Burn-in and Test Socket (BiTS) workshop was sponsored by the Test Technology Technical Council of the IEEE Computer Society. BiTS is the only IEEE sponsored workshop dedicated to providing a forum for the latest information about the socket industry.

Technical Program

20 presentations, covering a range of important socketing topics, were delivered by suppliers and users. The presentations were organized into 8 sessions: four sessions on Monday, 2 on Tuesday and 2 on Wednesday. At registration, attendees received the Proceedings, which contain all of the presentations.


BiTS 2001 Expo (Supplier Displays)

1:00PM –Electrical and Mechanical Modeling and Analysis

This afternoon's four paper session was a follow-on to last year's highly acclaimed Characterization and Evaluation session: 2 papers won awards and it had the highest number of hits on the BiTS website. Experiences, techniques and tools for mechanical and electrical modeling, analysis, evaluation and testing were discussed. Topics included a range of work on socket contacts, alignment and RF response.

  • "Review Of Burn-in Socket Contact Platings"
    Thomas A. Bradley, Agere Systems
  • "A Finite Element Analysis Of Solder Balls On A BGA Package In Sockets During Burn-in"
