Grinding induced subsurface cracks in silicon wafers


the machining processes (such as lapping and grinding) has to be removed by its subsequent processes. Therefore it is essential to assess the subsurface damage for each machining process. This paper presents the observation of subsurface cracks in silicon wafers machined by surface grinding process. Based on crosssectional microscopy methods, several crack configurations are identified ...

GRINDING MACHINES


the process is as much a cutting action as drilling, milling, and lathe turning. The grinding machine supports and rotates the grinding abrasive wheel and often supports and positions the workpiece in proper relation to the wheel. The grinding machine is used for roughing and finishing flat, cylindrical, and conical surfaces; finishing internal cylinders or bores; forming and sharpening ...

Additional services to be offered are datamining, control loops tuning, circuit/equipment process audit, and maintenance, as well as training and operator support services (JämsäJounela et al., 2005 ...

AP42, CH : Ceramic Products Manufacturing


Fine grinding or milling reduces the particle size down to as low as micrometer (µm) (4 x 105in.) in diameter. Ball mills are the most commonly used piece of equipment for milling. However, vibratory mills, attrition mills, and fluid energy mills also are used. Crushing and grinding typically are dry processes; milling may be a wet or dry ...

An Introduction to the Optics Manufacturing Process


 · grinding process. As the polishing process continues, the pitch will slowly conform to the shape of the optic so that the surface of the optic is smoothed out, but its overall radius is not changed. To aid in removing debris, grooves are cut along the pitch to allow slurry to flow more readily between the tool and the optic. A hole is also cut in the pitch at the center of the tool since pitch ...

Ball Mills


 · In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment. In present day practice, ore is reduced to a size many times finer than can be obtained with crushers. Over a period of many years various fine grinding machines have been developed and used, but the ball mill has become standard due to its simplicity and low operating ...

Energy and temperature analysis in grinding


Welldesigned grinding processes usually enhance workpiece surface quality producing low roughness, compressive or neutral residual stresses and improved fatigue life. Grinding is a very efficient process for machining hard materials and has the potential to achieve high accuracy of shape and size. Conversely, abusive machining can lead to a range of forms of surface damage. Generally, it is ...

Lapping and Polishing Basics


grinding process must be a balance of material removal and subsurface damage. In many cases it is advisable to initially cut the specimen with a gentle mechanical method such as a wire saw. A properly prepared wire saw cut sample can eliminate the grinding process altogether. : Lapping Lapping is the removal of material to produce a smooth, flat, unpolished surface. Lapping processes are ...
