Used MULTITEST MT 8501 #138604 for sale

MULTITEST MT 8501 is a state-of-the-art handler designed to be used in Automatic Test Equipment (ATE) systems. It is a highly advanced wafer handler for multi-site testing that enables the efficient testing of high-volume production. MT 8501 is built from three main components: a precision vacuum hopper, a pre-aligner with lift tabs, and a rapid-movement transfer stage. The vacuum hopper on MULTITEST MT 8501 utilizes angle sensing technology to detect the angular orientation of the wafers, allowing the handler to accurately move and position wafers. The system allows up to 200 wafers to be searched simultaneously, and each wafer can be individually move and handled. Additionally, MT 8501 can pick up and place large wafers up to 300mm in diameter. The pre-aligner with lift tabs allows the operator to perform x-y positioning of the wafers more efficiently than other techniques. The lift tabs provide a secure grip on the wafer without damaging it, and the pre-aligner ensures that the wafers are correctly aligned with respect to the test head before testing. Lastly, the rapid-movement transfer stage allows for fast and accurate wafer transportation between two test heads. This allows for parallel testing on two independent test heads and reduces throughput time significantly. Overall, MULTITEST MT 8501 is an advanced, precision wafer handler that enables efficient and accurate testing of high-volume production. It is reliable and easy-to-operate, making it well-suited for a variety of ATE systems. The efficient wafer handling, pre-aligning, and rapid-movement transfer capabilities make MT 8501 an ideal choice for production operations.
