Used SPEEDFAM 20B-5L #293813756 for sale

SPEEDFAM 20B-5L is a wafer grinding, lapping and polishing equipment used to create precise surfaces and surfaces with a high degree of flatness. This system is a fully automated, computer controlled robust machine, with a high throughput, providing repeatable and high-quality results. It is highly versatile and can be used to process a wide range of device sizes from a few millimeters to several inches. 20B-5L is equipped with a grinding head, lapping plate and polishing plate, all mounted on a precision, two-axis double riderhead. This head is designed to speed up workflows, allowing for efficient production and increased yields. The grinding head has a diamond abrasive that is used to penetrate, shape and rough up the surface of the wafer. An internal cooling fluid is used to maximize cutting efficiency and reduce heat generated during the process. The lapping plate is comprised of a large, flat, textured surface, which is used to reduce high areas and provide an even surface across the wafer. In order to optimize the process, the lapping and polishing plates can be programmed with up to 20 different parameters. This includes the speed, amount of time, and pressure to be used during the process. Additionally, the plates can also be adjusted for different substrates, allowing for greater control over the outcomes. Finally, the polishing plate is composed of a fine diamond abrasive, used to further refine and polish the surface of the wafer. This is done by gradually reducing the surface irregularities until the desired level of flatness is achieved. Again, the final surfaces can be controlled for different substrates, allowing for increased accuracy and repeatable results. In conclusion, SPEEDFAM 20B-5L is a high-performance wafer grinding, lapping and polishing unit. It is easy to use and is highly capable of providing precise, repeatable and high-quality results with minimal effort. Its diamond abrasive components, adjustable parameters, and internal cooling machine enable it to efficiently and effectively produce a wide range of surface types, as well as provide consistent results regardless of the substrate used.
