UENO SEIKI RV36-NEO die sorter

UENO SEIKI Test Handler RV36-NEOWhile the RV36-NEO shares the title of "fastest" with the RV16-NEO, the core distinction between them lies not in their base operating speed, but in their modular capacity. The manufacturer presents them together, with a clear functional distinction: the RV36-NEO is designed for scenarios requiring a larger number of optional modules, whereas the RV16-NEO is tailored for streamlined, minimalist configurations.

Modular Capacity

This is the only dimension explicitly highlighted by the manufacturer as a differentiator between the two models. The RV36-NEO supports a greater number of integrated optional modules, making it ideal for production lines that—beyond simple sorting—require additional capabilities such as electrical testing, failure-binning, ARC (Automated Reel Change), tape feeding, or 2D code reading. In short, it is a system engineered with the physical and systemic headroom to accommodate future upgrades. The RV16-NEO, by contrast, is better suited for production lines focused solely on visual inspection and taping, with no plans to add further functions in the near term.

Shared Core Specifications

Both models offer identical baseline performance: a throughput of 70,000 UPH; support for 6-, 8-, and 12-inch wafer frames; output tape widths of 8 mm or 12 mm; and compatibility with die sizes ranging from 0.2 mm to 5 mm and thicknesses from 30 μm to 1 mm. Inspection options for both include six-sided visual inspection, thickness measurement, in-pocket inspection, post-sealing inspection, infrared (NIR/SWIR) inspection, 3D height measurement, bump coplanarity, color imaging, and AI-assisted inspection.

Selection Logic

If a production line currently requires only high-speed sorting and visual inspection—with little likelihood of needing additional modules later—the RV16-NEO serves as a more streamlined, efficient choice while delivering the same core performance. Conversely, if there is a possibility that functions like electrical testing or marking might be required in the future, and you wish to avoid replacing the entire machine, the RV36-NEO’s expansion headroom provides tangible value. Ultimately, the choice between the two comes down to how one accounts for "uncertainty," rather than a difference in raw performance capabilities.
