The NeonTech NDS-4200 is a fully automated, dual-spindle dicing saw designed for 8-inch (200 mm) workpieces. Within NeonTech’s product lineup, it serves as the 8-inch counterpart to the NDS-5200 (12-inch model), with its primary function being the facilitation of fully automated, "lights-out" mass production—from loading to cleaning—for medium-sized wafers.
Core Architecture
The system is equipped with two air-bearing spindles, each delivering an output power of 2.4 kW and operating at speeds ranging from 10,000 to 60,000 rpm. It is capable of processing a variety of materials, including silicon, ceramics, BGA, LEDs, and PCBs. The machine features a granite base combined with a bridge-style structure, engineered specifically to suppress vibration and enhance rigidity, thereby providing a stable foundation for high-speed, dual-spindle operation.
Precision and Motion Specifications
The Y-axis (indexing axis) offers a unidirectional pitch accuracy of 0.001 mm/5 mm, a positioning accuracy of 0.002 mm/200 mm, and a minimum step increment of 0.1 μm. The X-axis (dicing axis) has a travel range of 400 mm, a dicing speed of 0.01–400 mm/s, and a minimum step increment of 1 μm. The θ-axis provides a rotation range of 380° with an angular resolution of 0.000176°.
Automation and Operation
The system supports a fully automated "cassette-to-cassette" workflow, encompassing loading, pre-alignment, optical alignment, dicing, spin-cleaning, and unloading—all performed automatically by the machine. It is operated via a 17-inch touchscreen interface, which supports multiple languages, including Korean, English, Chinese, and Japanese. The machine’s overall dimensions are 1270 × 1700 × 1850 mm, with a weight of approximately 2000 kg. For applications requiring the processing of 8-inch wafers, large-format ceramics, or PCBs—and where fully automated, continuous production is essential—the NDS-4200 offers a compelling solution for high-volume manufacturing, combining the efficiency of a dual-spindle configuration with the stability of a granite platform.
