The LINTEC Adwill series includes UV curable dicing tapes, high performance back grinding tapes, dicing die bonding tapes required for semiconductor packaging, and backside coating tapes. Adwill continues to make steady progress in the advancement of related equipment and unique systems.
Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm.
Nonetheless, the most common applications involve grinding and cutting with resin-bonded wheels. The old adage "accidents can happen" applies to grinding and cutting just as it does to most aspects of our daily activities, whether it be walking down a flight of stairs or driving our cars.

Dec 08, 2016· A downside of centerless grinding is you can't have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That's why we like to say that where machining ends, the centerless grinding process begins.

The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.

Cutting and grinding is performed on many jobsites. The following are a list of safety precautions that must be followed to prevent injury or property damage. Stay alert and watch what you are doing. Do not use tool while tired or under the influence of drugs, alcohol or medication.
1. Center type grinding with axis feed: (Work spins slower) similar to cutting thread in the lathe. difference a shaped grinding wheel is used instead of the point cutting tool. (even multiple shaped grinding wheel can be used ). Speed –given by the RPM of the grinding. Several passes are necessary to complete the thread. 2.

Methods of grinding spices evolve over the years. Long time ago, when human beings started processing their food, they discovered that some plants could be stored longer and also tasted nicer if they were pounded with stones or ground finely.
WET GRINDING. The raw materials are taken in a ball mill and them grinded with water for certain hours. The grinding media is usually alumina because it has good wear resistance and good density. This process is known as wet grinding. The raw material will be obtained in a slurry form at the end of the wet grinding process.
• Use caution when grinding in corners because a sudden, sharp movement of the grinder may occur when the wheel strikes the secondary surface. • Maintain an angle of approximately 15° to 30° between the disc and the working surface . • Do not apply side pressure on the grinding or cutting wheel.
The process of producing feed pellets can roughly be described as a plastic molding operation of the extrusion type. Feed ingredients are made up of various compounds such as proteins, acids, sugars, fibers, and minerals. These products can be softened (conditioned) by the addition of heat and water.
