Automated on-chip burn-in system for TAB reels

A tape automated bonding (TAB) burn-in on reel system is discussed. This system has demonstrated its ability to produce significant cost advantages over singulated TAB carrier burn-in systems. The cost advantages result from the elimination of burn-in boards, higher burn-in process yields, and reduced part load/unload times. The costs for reliability testing have also decreased because of design, purchase, and debug of long-term life and moisture resistance boards is no longer required. The elimination of reliability test hardware allows larger sample sizes to be used for product reliability qualifications. Hence, higher part quality and reliability can be obtained
