Abstract

The invention provides a cooling device of a built-in motor of a motorized spindle and a dicing machine. The cooling device comprises a cooling liquid providing part which is used for providing cooling liquid and a cooling liquid passage which is used for inputting the cooling liquid which is provided by the cooling liquid providing part and controlling the flow direction of the cooling liquid. The cooling device of the built-in motor of the motorized spindle and the dicing machine can stably cool the motor of the spindle when the motorized spindle is working.

Description

technical field [0001] The invention relates to integrated circuit packaging equipment, in particular to a cooling device and a dicing machine for a built-in motor of an electric spindle. Background technique [0002] The dicing machine is the key equipment for the post-packaging of integrated circuits, and its function is to divide the wafer into individual circuit units. The dicing machine generally uses a high-speed aerostatic electric spindle as the core executive component to achieve high-precision powerful grinding. In this kind of dicing machine, the performance indicators such as the stiffness, rotation accuracy, output power and reliability of the aerostatic electric spindle directly determine the cutting quality of the dicing machine. With the rapid development of the integrated circuit manufacturing industry in the direction of high precision and high speed, the quality requirements of wafer dicing are getting higher and higher. [0003] When the dicing machine ...
