Used LAPMASTER 15-0 #9117043 for sale

LAPMASTER 15-0 is a wafer grinding, lapping, and polishing equipment designed for production sized wafers within the semiconductor industry. It is designed to combine low cost with high performance with its 4 to 15 inch grinding and polishing accuracy. This system features a unique and patented process technology, which has been proven in the field with highly reliable results. The process includes an air abrasive wafer grinding technique which is backed up by other processes such as lapping and polishing. The air abrasive process uses small abrasive materials which are suspended in an air stream and propelled towards a wafer surface to grind it very evenly. This low-cost process is effective and is recommended for wafer production. The lapping process is used to promote uniformity and repeatability. 15-0 uses automated data acquisition and analysism to continually monitor process results. This ensures that each wafer is accurately finished to the required specifications. The lapping process is capable of leveraging up to 16 lapping plates using either wet or dry lapping techniques. The wet lapping technique utilizes a contained air environment which is clean and free of contaminants, while the dry lapping technique uses a ceramic or metal slurry medium. The polishing process helps to smooth out any roughness due to the lapping process and is used to bring the wafer into the precise dimensions and surface finish requirements. LAPMASTER 15-0 includes a 6-stage polishing unit featuring either conventional slurry or an automated slurry metering machine. This allows for precise control over slurry concentration, flow-rates, and process rates for electro-plated and non-plated substrates. It is designed to be able to operate at high production rates. 15-0 features a computer interface which allows for complete monitoring and control of the entire tool. This includes a range of automated processes, including fully automated wafer loading and unloading, as well as automated trickles for the lapping and polishing processes. LAPMASTER 15-0 is a robust and highly reliable asset which is designed for high-volume production within the semiconductor industry. It utilizes many different processes such as air abrasive grinding, wet and dry lapping, and polishing in a fully automated production routine. This model offers low cost processing, reliability, and accuracy, allowing for high-quality production results.
