Oscillators
Vishay Intertechnology's new pair of clock oscillators feature a 3.3-V input and a 1- to 70-MHz range. They also feature TTL and HCMOS compatibility and a tri-state feature that allows the output to be placed into high-impedance state. Standard and industrial temperature ranges are available with two through-hole hermetically sealed package options: 14-pin DIP and half-size 8-pin DIP. Input currents for the oscillators range from 10 to 30 mA, with rise and fall times of 10 ns maximum. A ±100 ppm frequency stability over operating temperature range is standard, with ±25 and ±50 ppm available. The new oscillators will provide clock signal sources for digital ICs and microprocessors in low-power applications, such as computers, portable peripherals and communications equipment.

Solder Paste Printer
The Panasert SPF Super Print solder paste ma chine delivers fast printing speed and cycle- times as low as 8 seconds per board. It uses an open-type, high-speed squeegee head de signed to maximize speed up to 220 millimeters per second and improve solder paste printing time. It delivers accurate printing for components from 0603 microchips to 0.3-mm pitch QFPs and 0.5-mm CSPs. It also uses a high-speed vacuum to remove solder paste from the underside of the screen mask preventing clogs from forming in the opening. Panasonic Factory Automation Company, Franklin Park, Ill.
Media Transfer System
The ST-595-2 fully automated media transfer system combines fast changeover with high throughput, offering safe, reliable high-speed handling of QFP, TSOP, LCC, BGA, CSP and similar devices. A full range of vision inspection capabilities is said to ensure high quality and eliminate product defects for end-of-line production. Features include software that eliminates the need for application-specific tooling and adjustments during changeover and requires no camera recalibration. Parallel device handling enhances throughput. Two pick-and-place heads can rotate 90, 180 and 270 degrees. The system may also be configured for tray-to-tape or tray-to-tray operation. RVSI, Canton, Mass.

Temperature Sensor
The Temprobe has been developed for use in lead-free soldering, where peak temperatures can reach 275°C. It is a precision temperature-sensing tool that can be placed anywhere a temperature reading is required, even in solder paste. It will plug directly into any standard type "K" thermocouple profiler or readout device. The Temprobe maintains high-contact pressure on the thermocouple to ensure accurate, repeatable readings. Saunders Technology Inc., Hollis, N.H.

Photoetching
The photoetching process allows Tech-Etch to produce intricate components that cannot be duplicated by other production methods. Custom light-gauge parts can be manufactured with intricate patterns, precise tolerances and burr-free edges with exact repeatability. Metals, such as beryllium copper, stainless steel, aluminum, titanium, molybdenum, brass and spring steels, as well as polyimide film for flexible circuits, can be etched. Parts can be as thin as 0.005 inches. Special processes, such as assembly and finishing, are also available. Tech-Etch, Plymouth, Mass.
Wafer Stepper
The Saturn Spectrum 300 offers 300-mm lithography capabilities to customers in the flip-chip (bump) processing arena. The system's introduction is timed to coincide with chipmakers' current transition to larger-diameter wafer processing and is said to offer a new breed of stepper to accommodate the intricate packaging requirements of highly specialized bump applications. It builds on Ultratech Stepper's 1X lithography system with a broadband lens that allows for automatic selection of exposure spectrum (i-line, gh-line or ghi-line). The tool reportedly has a low numerical aperture lens design. Ultratech Stepper Inc., San Jose, Calif.
Integrated Fabless Solutions
Integrated Fabless Solutions is a set of integrated services delivered across the silicon cycle, including test strategy consulting; silicon validation and characterization; silicon debug and repair; integrated test solutions; remote collaboration; deployment to high-volume manufacturing; and education program planning and consulting. These services, combined with Schlumberger's Technology Centers, are said to enable fabless customers to reduce engineering cycle time and move devices to high-volume manufacturing more quickly.

Proximity Mask Aligner
The Reel-to-Reel Proximity Mask Aligner is for volume production of tape for tape carrier packages (TCP) and flex-based CSPs, like the µBGA. The tool, called the MA100RR, can reportedly also be used for products requiring very fine patterns on flexible materials, such as flex-based displays. It is said to offer high resolution of better than 5 µm that is achieved by distortion-free proximity printing, even on wide foils. Karl Suss, Munich, Germany.
Laser Tray Marking System
The U-1481 system is a new laser tray marking system designed to mark semiconductor components. Designed for hand loading with a left-to-right feed, the system is said to offer a suitable solution for applications with small lots and frequent changeovers. It uses Markem's 3000 Series direct laser to mark semiconductor units in a JEDEC tray and features the ability to be loaded and unloaded during the marking cycle for greater throughput.
