die sorter

Chip sorters are core equipment in semiconductor packaging, acting as the "quality gatekeeper".

Demart provides a complete set of solutions for chip sorters, including the high-response HD series turntables with a settling time of up to 20ms for maximum sorting efficiency, as well as various pick-and-test components and management software.

Solution Details

After wafer dicing, the equipment performs high-speed identification, pickup and testing of millimeter-sized bare die through precision machine vision and micron-level control. It can instantly complete electrical testing and optical screening, accurately determine the performance grade and quality of each chip, and automatically sort them into corresponding carrier tapes.

This not only weeds out defective chips in advance to avoid waste of subsequent packaging costs, but also provides critical data feedback for front-end processes. Its sorting accuracy and efficiency are directly related to the final quality and production cost of chips, making it an indispensable key link for improving the yield and efficiency of semiconductor manufacturing.
