Used SPEEDFAM 9B-5 #9215190 for sale

SPEEDFAM 9B-5 is a precision grinding, lapping and polishing equipment designed for the high-precision production of extremely flat surfaces on semiconductor wafers. With its advanced design construction and exceptionally high performance to price ratio, 9B-5 is ideal for high volume production and low yield polishing. The system features a quick change bed configuration built for maximum performance and efficiency, allowing for easy wafer handling and exchange of lapping and polishing components. SPEEDFAM 9B-5 also features the latest in digital signal processing (DSP) technology for accurate wafer data acquisition and storage. It is built with a powerful 850-W motor with programmable digital signal processor to ensure synchronized speed, reducing vibration and increasing terbore accuracy when grinding and polishing g. 9B-5 is designed to quickly and accurately process both single- and double-sided wafers as well as large-area wafers up to 8" in diameter. The lapping and polishing components can be precisely adjusted with the servo-controlled operation allowing both step feed and continuous feed operations. All of the parts that come into contact with the wafers are made of hard wearing material to ensure a long life and the flatness of the wafer is ensures with the in-line optical unit. The machine makes use of standard diamond abrasives and a range of white alumina slurries, assuring a higher standard of surface finish. For even faster wafer processing, SPEEDFAM 9B-5 can be configured to give a continuously variable polishing speed, ensuring reduced potential for miss-polish and increased productivity. The burr process can also be adjusted with the variable speed controlled tool in order to reduce the potential for chipping or flaking. The safety of the asset is insured with a high oxygen content in the process chamber, ensuring a clean and protective environment for the wafers. 9B-5 is an advanced wafer grinding, lapping and polishing model, built for precision and a high-speed, high-yield production. It is perfect for applications where a higher degree of accuracy and rate of production is required.
