Description
Technical Field
[0001] The utility model relates to the technical field of heat dissipation, in particular to a rapid heat dissipation structure of a diamond dicing knife. Background Art
[0002] The dicing process is an important process in semiconductor packaging. This process uses a high-speed rotating dicing blade to cut the entire wafer into individual chips. It can cut a variety of materials such as solar panels, glass, silicon wafers, ceramics, LEDs, integrated circuits, etc. With the continuous emergence of new materials and technologies, a new type of semiconductor material needs to be cut in an environment without water cooling, which puts higher requirements on the heat dissipation of the blade.
[0003] Currently, most diamond scribers are used in a waterless environment. After a long period of cutting, the temperature of the diamond scriber increases. In this case, water cannot be used directly to cool the outer surface of the diamond scriber, because most new semiconductor materials cannot come into contact with water. If the temperature of the diamond scriber is too high, the cooling effect of the blade is poor. Continuing to cut will result in poor cutting quality and a short blade life. Utility Model Content
