The Pegasus S200A automatic 200mm prober from Wentworth Laboratories, Inc. is the latest addition to the company's wafer prober line. Intended for high-volume wafer probing of light emitting diodes (LEDs), it also tests discrete devices and wafers up to 200-mm. Pegasus S200A is integrated with production LED testers to bring a fully automatic test platform to the LED production test floor.
The prober uses LabMaster control software, an intuitive graphics user interface which centralizes real-time monitoring and test setup of the prober, accessories, and test progress. Mapping capability provides real-time yield analysis of both the wafer and lot under test, and advanced utilities reportedly permit the experienced user to design sophisticated test routines. LabMaster enables the Pegasus S200A to seamlessly integrate with other testers using standard communication protocols, while simultaneously communicating with all prober accessories.
Pegasus S200A features fast precision stage, optical character recognition, bar code recognition, probe mark inspection, and ink dot inspection. Advanced robotics are said to maximize throughput of full, partial and diced wafers in lots of 25, ranging from 50 to 200-mm. Wentworth Laboratories Brookfield, CT, www.wentworthlabs.com
