Used SPEEDFAM 9B-5B-IV #9223853 for sale

SPEEDFAM 9B-5B-IV is an advanced grinding, lapping and polishing equipment designed for precision abrasion, polishing and surface modification of wafers. The system uses a combination of three special abrasive wheels to process wafers. All wheels are fixed in a sealed environment and rotate in a vertical plane for precise grinding and polishing. The grinding and lapping wheels are made up of either fine or coarse aluminum oxide grains which are fixed to a composite spindle. This spindle spins at a precise speed allowing the grinding and lapping process to occur without damaging the wafers. The grinding process creates a flat surface on the wafer, while the lapping process improves the surface finish. The finishing wheel of the unit is a polycrystalline diamond (PCD) wheel. PCD is significantly more abrasive than aluminum oxide and is used to increase the surface roughness of the wafer. This is achieved by a precise oscillating movement combined with a gradual increase in the wheel's RPM. This process removes smaller particles, allowing a higher degree of precision. 9B-5B-IV machine has a modular design allowing simple maintenance and repair. It includes a built-in protective cabinet that shields operators from potential dangers associated with the abrasive process. The entire tool is monitored and controlled via PLC and PC and configured for operators to select the correct grinding process. Data logging and reporting is available for tracking process and part history. This asset was designed with automation in mind. It is capable of processing up to 50 wafers per hour with minimal setup time and a relatively small footprint. The model can be customized to fit customer's specific needs, including the ability to add multiple tools and modules. Overall, SPEEDFAM 9B-5B-IV is a powerful tool for precision wafer grinding, lapping and polishing. It is able to accurately produce flat and smooth surfaces, while also providing excellent surface finish. The equipment's automation capabilities allow it to be configured to meet specific production needs.
