Used SPEEDFAM 22B-5L #9156533 for sale

SPEEDFAM 22B-5L is a wafer grinding, lapping & polishing equipment designed to provide reliable and consistent performance in wafer grinding, lapping and polishing of smaller semiconductor wafers. The system has five lapping surfaces which can be adjusted to the micro surface required by customization specifications. The lapping surfaces measure 2", 3", 6" and larger, allowing for a range of wafer sizes to be processed. The main body of 22B-5L is comprised of a base unit and an upper lapping carriage. The lapping carriage is directly driven by a motor-driven spindle and is independently suspended to ensure optimal grinding surface contact. The lapping surface also includes a vacuum clamping unit that securely holds wafers in place. The lapping process is performed using a unique diamond-abrasive grinding process that uses a special electroplated diamond disc. The diamond-abrasive lapping process provides superior uniformity and accuracy within tight tolerances of finished wafer surface. SPEEDFAM 22B-5L also features an advanced lapping and polishing control machine that controls the positioning and speed of the lapping surface as well as the amount of lapping pressure applied to the wafer. This feature ensures that the wafers are processed with the same pressure, greatly increasing the consistency and accuracy of the final product. In addition to the above features, 22B-5L has several advanced safety features built in. These features include a full safety circuit tool ensuring the operator's safety during operation, as well as a self-diagnostic asset that monitors the status of the model and any potential errors and alerts the operator. Overall, SPEEDFAM 22B-5L is a durable and reliable wafer grinding, lapping and polishing equipment designed to deliver consistent results with the highest accuracy. It's suitable for use in semiconductor wafer production and provides superior grinding surfaces for a variety of wafer sizes. The machine's advanced control system and safety features ensure that the operator is safe and that the process is performed efficiently and consistently.
