In the manufacturing process of IC, electronic circuits with components such as transistors are formed on the surface of a silicon crystal wafer. Basics of IC formation. A thin film layer that will form the wiring, transistors and other components is deposited on the wafer (deposition). The thin film is coated with photoresist. The circuit pattern of the photomask (reticle) is then projected ...
Previous attendees have reported back major cost-savings and generally better grinding and troubleshooting by gaining a logical, scientific approach to grinding. In-depth, long-term grinding education: The High Intensity Grinding Course is three days long. However, for many attendees, the course is just the beginning of their grinding education.
Faulty grinding operation: Prevent wheel edge from digging in workpiece. Grind workpiece under light load which provides low grinding force, and use additional steady rests so that it cannot be inclined by grinding force. Reduce table speed or change some speed per pass. Spiral feed marks: Contact with wheel edge: Round off wheel edges. Wrong ...
