Used NTS 36G DMP SL910-AFCL #9268069 for sale

NTS 36G DMP SL910-AFCL is a state-of-the-art wafer grinding, lapping and polishing equipment designed by NTS Japan to process high-quality wafers. The system consists of a 36" diameter wafer grinding wheel and an 8.5" diameter lapping and polishing wheel that rotate simultaneously and remain in contact with each other. The grinding wheel is driven by an AC motor and the lapping and polishing wheel is driven by a brushless DC motor. The grinding wheel uses a combination of diamond grain and a polyurethane elastomer, which allows it to accurately grind wafers at a speed of 3500 rpm. An array of conveyer belts ensure smooth loading and unloading of wafers into the machine. The two wheel unit ensures the grinding of even more complicated geometries with minimal damage to the wafer surface. The lapping and polishing wheel uses a combination of diamond grains along with a rubber bond for polishing. Once the grinding process is finished, the lapping and polishing wheel rotates to a speed of 6000 rpm. This removes the surface remnants left after grinding and produces a smooth, glossy finish with transparency. This wheel has a minimum lap length which reduces the losses incurred during the polishing process. The processor is also equipped with six RF machines with variable power output that can be adjusted based on the size of the wafer. The machine further consists of a vacuum turntable with an adjustable speed and angle. This ensures superior surface finish even on extremely large wafers. Overall, 36G DMP SL910-AFCL is an advanced tool that provides semi-automatic operation with user-friendly features like a digital display. Its integrated asset and efficient power output ensures precise grinding, lapping and polishing of wafers, which helps achieve the highest quality results.
