Wescon-IC Expo 97

The Wescon-IC Expo has expanded its bandwidth and for the first time in trade event history will utilize both the San Jose McEnry and Santa Clara convention centers. More than 1,400 booths will display electronics innovations and applications for next-generation electronic, computer, and communications systems.

In addition to focusing on communications, multimedia, power management, and application technologies, the conference will emphasize IC technologies, as well as networking and wireless communications topics. Attendees will find half-day workshops, sessions, and half- and full-day short courses on a range of topics encompassing processor/DSP, ASIC, and programmable chip design.

Three high-profile keynote event addresses will include John P. Morgridge, chairman of the board, Cisco Systems Inc.; Chet Silvestri, president of Sun Microsystems' Sun Microelectronics division; and Curtis Crawford, president, Microelectronics Group, Lucent Technologies Inc. The latter is part of Lucent Technologies' celebration of the 50th anniversary of the transistor, first invented by engineers at Bell Labs.

Continuous shuttle bus service during show hours and passes for the Silicon Valley light rail system's Guadalupe line are available at no cost.

Approximately 50,000 engineering professionals are expected to attend. Wescon is co-sponsored by the Los Angeles and San Francisco Bay Area Councils of the Institute of Electrical and Electronics Engineers (IEEE) and the Southern and Northern California Chapters of the Electronics Representatives Association (ERA). It is produced by Electronic Conventions Management.

Composite cases

Val-An Composite Series of cases are for transporting electronics and other sensitive equipment. Superior stiffness and fatigue endurance provide dimensional stability against distortion, bowing, twisting, and impact. The cases, which are available in thousands of sizes, are watertight and offer inner panel options, a pressure-relief valve, and a wide choice of colors. Although they are lightweight, these cases feature high fracture and residual strength. Their low energy dissipation on impact provides excellent dampening properties through rapid decay of mechanical vibrations.

PEM(R) R' ANGLETM self-clinching fastener provides a strong right angle attachment point for aluminum sheets as thin as 0.040 inch/1.02 mm. The second sheet or component can be securely fastened to the PEM R' ANGLE with a thread-forming screw by using the self-clinching principle. This self-piloting screw forms its own thread as it is installed. The result: a thread fit which resists vibration and demonstrates excellent strip-out characteristics. In addition, the holding power of the fastener is not compromised by the repeated removal and re-installation of the screw.
