This was the inaugural Burn-in and Test Socket (BiTS) workshop. Sponsored by the Test Technology Technical Council of the IEEE Computer Society, the new workshop dealt with Burn-in and Test socketing topics. The program ran from Sunday, February 27, 2000, through late Tuesday afternoon.

Technical Program

Over 20 presentations, from suppliers and users, were delivered (view foils). They were organized into 7 sessions: two full sessions on Monday, plus 3 full and 2 concurrent sessions on Tuesday. Attendees received a copy of the presentations at registration.


BiTS 2000 Attendees

BiTS 2000 brought 201 participants from around the world representing end users and suppliers of sockets, boards, burn-in systems, handlers, packages and other related equipment, materials and services.
