GRINDING, EVG SERIES
HIGH PRECISION VERTICAL GRINDING MACHINES The EVG Series Vertical Grinding Machine is designed to grind advanced materials to a high degree of precision in flatness and surface quality, LAPPING AND POLISHING often reducing or eliminating the need for lapping. The compact design with advanced controls and process monitoring make this an ideal machine for use in research & development or for pilot line production of advanced components.
Some of the ideal applications for the EVG Series:
• Semiconductor wafer grinding or back-thinning (SiC, GaAs, Sapphire, Si, GaN, AlN, InP) • Semiconductor equipment components (ceramic chucks, glass ceramic) • Substrates for semiconductor advanced packaging including MEMS (ceramic, polyimide)
SIZE OPTIONS The EVG models are available in three different sizes. Customized models upon request.
World Leader in Superabrasive Finishing Systems GRINDING, ADVANCED CONTROL OPTIONS The EVG-AD and EVG-ADM models are equipped with controls that provide automated grinding wheel dressing, automated positioning of the grinding wheel relative to the workpiece and workpiece thickness measurement. For maximum control, an upgrade to in-process thickness measurement with feedback to the grinding cycle in real-time, is available. The ADM model offers automated thickness options: multi- point contact probing for multiple wafer grinding or a choice of contact or non-contact continuous in- process measurement for single wafer. LAPPING AND POLISHING
* Continuous measurement (only for single wafer).
GRINDING WHEEL TECHNOLOGY
The EVG Series machines are equipped with Engis grinding wheels based on the MAD Wheel (Mixed Abrasive Diamond) technology, which tailors the wheel to the material being processed. Consult your Engis application engineer for specific process recommendations for your material.
