Wafer backgrinding, or wafer thinning, is a semiconductor manufacturing process designed to reduce wafer thickness. This essential manufacturing step produces ultra-thin wafers for stacking and high-density packaging in compact electronic devices. The silicon wafer backgrinding process is complex. You need a company experienced enough to ...

Upgrading cement grinding systems offers both process and commercial benefits. The use of a high-pressure grinding roll in semi-finish grinding mode significantly reduces and space. Therefore, Germany-based Maschinenfabrik Köppern has developed a compact air classifier that enables grinding system upgrades by integrating only one combined machine.

High-rigidity grinder is the device to grind the hard and brittle materials such as sapphire and Sic substrates that are considered to be hard-to-cut materials. High Rigid Grinder: HRG3000RMX. Fully Automatic High Rigid Triple Axis Grinder. Catalog PDF (619.5KB) High Rigid Grinder: HRG300/HRG300A. HRG300 allows the processing of individual ...

Ideally, grinding and superfinishing operations should be synchronized to achieve the common goal of producing consistently good parts at the end of their interrelated processes. The grinder needs to take the workpiece to size within a prescribed semi-rough finish range and then leave it alone. There is a relatively narrow window in which to ...

Tele-Operated Robotics for Grinding, Finishing. Jan. 17, 2013 ... Using semi-automatic mode the programmability and excellent path-following capabilities of the system can be exploited. Operators have access to a variety of preprogrammed and stored surface finishing subroutines to remove feeder or flow-off contacts automatically.

Also known as grinding, roughing or rough grinding, coarse finish usually applied before manufacturing #4 Architectural AKA brushed, directional, or satin finish, fine uniform polishing lines ... #6 AKA fine satin finish, less reflective than #4 architectural finish #7 Semi-bright finish with some very dull polishing lines #8 AKA mirror finish ...

In fact, grinding is often considered a subset of cutting, and vice versa, since each grain of abrasive on a grinding wheel acts like a microscopic, sharp cutting edge that shears a tiny chip from a part surface. In general, precision metal grinding processes are used to remove small amounts of material in order to achieve a particular finish ...

The number 4 finish is a common but specialist stainless steel finish that cannot be achieved by a rotary abrasive such as a disc. Its linear appearance can only be achieved with a belt or wheel. In this case, the previous step is …

Semiconductor Back-Grinding The silicon wafer on which the active elements are created is a thin circular disc, typically 150mm or 200mm in diameter. During diffusion and similar processes, the wafer may become bowed, but wafers for assembly are normally stress relieved and can be regarded as flat.

the semi-finished state having been squared up and milled. Finishing the part will require the precision finishing of the six faces of the block to tolerances common to precision grinding for squareness, size, and surface finish characteristics. Other Evaluation Criteria 1. Finishes are at least 32 Ra microinches or better. 2. Free of sharp edges.

Semi-Flexible Grind and Finish Wheels (15) FLEXCEL Type 27 and Type 29 Semi-Flexible Wheels can remove material aggressively like a grinding wheel, and blend and finish like a sanding disc. FLEXCEL wheels flex to contoured surfaces giving a smooth finish without gouging. Faster stock removal than standard depressed center wheels.
