ISMECA NY32 test handler

The ISMECA NY32 is a 32-station rotary semiconductor testing/sorting/inspection system from ISMECA (now part of Cohu), Switzerland. It is designed for high-integration, high-volume, and high-precision back-end packaging and final testing scenarios, and is a core piece of equipment for mass production of RF, analog, power devices, and advanced packaging.

I. Working Principle (Rotary Parallel Processing)

The NY32 uses a 32-station precision rotary table to automate the entire testing, inspection, and sorting process through "parallel stations + synchronous rotation":

Feeding: Pallet/tube/reel feeding, with visual positioning and posture correction.

Rotary Rotation: 32 stations rotate synchronously, sequentially completing 6-sided optical inspection → infrared flaw detection → 3D morphology measurement → electrical testing → marking → sorting.

Core Actions:

Vision: High-speed camera + infrared penetration, detecting appearance/size/cracks.

Testing: Probe card contact, completing DC/RF/parameter testing.

Sorting: Categories are sorted by quality (Good/Defective/Grade) and output to reels/tubes/pallets.

Data Loop: The PAICe digital twin platform monitors in real time, and AI algorithms automatically correct parameters.
