ISMECA test handler NY20

The ISMECA NY20 (now owned by Cohu) is a 20-station rotary ultra-high-speed semiconductor testing and sorting machine, characterized by short testing times, high throughput, and low cost. It is a mainstay model for mass production of discrete devices, LEDs, and small-to-medium power ICs.

I. Working Principle (Rotary Parallel Processing)

The NY20 uses a 20-station precision rotary table, achieving full automation through "high-speed rotation + parallel processing":

Feeding: Vibratory feeder/linear track feeding with vision positioning and attitude correction functions.

Rotation: 20 stations rotate synchronously, sequentially completing six-sided optical inspection → infrared flaw detection → electrical testing → marking → sorting.

Core Actions

Vision: NV-Core platform high-speed camera + infrared penetration, detecting appearance/size/hidden cracks.

Testing: Up to 8 parallel testing stations complete DC/parameter testing.

Sorting: Classified by pass/fail/grade, outputting reels/tube packaging.

Data Closed Loop: The PAICe digital twin platform provides real-time monitoring, and AI algorithms automatically correct parameters.
