Used LAPMASTER 36B #9216461 for sale

LAPMASTER 36B is a patented wafer grinding, lapping and polishing equipment designed to provide superior planarization and roundness results on any substrate material. With a suite of powerful features and patented drive technology, the unit can quickly process wafers of all sizes and shapes - from 2" to 8" and beyond - with optimal materials removal and flatness. The unit's unique design utilizes a consolidated air bearing lapping diamond mandrel and workholder assembly, enabling simplified workflow and better consistency over traditional manual processes. The workholder can be indexed in 5˚ increments to support multiple processes, while gravity feed and counter pressure keep material in place. The high power drive system enables precise speed, position and acceleration control, offering 6000rpm maximum velocity. A fixed ratio direct drive with claw clutch eliminates large negative accelerations, allowing for improved tracking of wafer faces and uniformity of the final product. 36B also features a precise servo-controlled platens that move in a reciprocating or rotation motion, driven by a belt or direct drive motor. This makes it possible to achieve precise symmetric lapping to support high quality TTV levels. Additionally, the unit has an efficient air cooling unit that ensures a uniform temperature and uniform wear rate on the lapping plate, increasing material removal and repeatability. The unit comes with a range of options for fine grinding and honing. These include a unique RaMax™ platens to reduce RMS surface roughness, a multi-lane parallel polishing table for high throughput processing, and dedicated workholding for sharpening and honing. LAPMASTER 36B brings a powerful, precise and efficient solution for wafer grinding, lapping and polishing, offering consistent results across all substrate materials. Whether used standalone or as part of a complete processing machine, the unit helps streamline demanding operations and bring better quality control to production lines.
