Solid State Air Conditioners
A new line of thermoelectric/solid state air conditioners provides a broad range of thermoelectric cooling and heating protection in laser-based systems, scientific instruments and computer control packages for industrial and military applications. The systems are available in 400, 800 and 1500 BTU/HR sizes and reportedly feature reliable performance at high temperatures, compact size, vertical or horizontal mounting, low acoustic noise, low power requirements, NEMA 12 and 4X configurations, and the ability to withstand shock and vibration in mobile applications. Electrografics International Corp., Warminster, Pa.

SOI Wafer Inspection
The AW-2000 is an automated system that creates images through bonded SOI wafer pairs to locate voids, microvoids and other internal defects. The system is based on Sonoscan's C-SAM acoustic micro-imaging technology and uses a robot arm to remove a wafer from an incoming cassette, positioning the wafer for acoustic imaging. The ultrasonic transducer reportedly detects microvoids as small as 5 microns in diameter. Wafers up to 8 inches in diameter can be handled by the system, which finds defects in wafer pairs joined by direct bonding, glass frit bonding and epoxy bonding. After acoustic imaging, system software classifies each wafer according to the user's requirements, and the robotic arm places the wafer in the appropriate outgoing cassette. Stored data contains the information needed to apply accept/reject criteria to individual devices after dicing. AW-2000 inspection can be performed after initial bonding, annealing or thinning. After metallization has been deposited, the acoustic image is typically overlaid with a wafer map to relate local defects to specific devices on the wafer. Sonoscan Inc., Elk Grove Village, Ill.

De-taping Machine
The Model 249 de-taping machine is designed for rapid removal of surface mount technology components from Electrical Industries Alliance (EIA) embossed tape. The machine accommodates tapes between 8 and 44-mm wide, and removes ICs from reels and transfers them into tubes that are then ready for assembly and other production processes. The machine is said to eliminate incorrect orientation and lead defect errors that are created by handling devices during manual de-taping. The Model 249 reportedly has a throughput of up to 6,000 units per hour. After a reel is attached, a short section of cover tape is separated from the carrier tape, and the leading carrier tape edge is fed into the chip removal channel. Empty tapes are routed to exit channels for easy disposal, while removed ICs are loaded into tubes. The unit permits several application-specific settings and adjustments, including carrier tape feed speed, unit counting (increment or decrement), gap sensor sensitivity, shutdown timer, audible feedback (on/off) and password function.
