Description

Technical Field

[0001] This utility model relates to the field of chip cutting fluid circulation device, specifically a chip cutting fluid circulation device. Background Technology

[0002] Integrated circuits, also known as microcircuits, microchips, or wafers / chips, are a way to miniaturize circuits (mainly semiconductor devices, but also passive components) in electronics. They are often manufactured on the surface of semiconductor wafers. Chips need to be cooled during dicing. The wastewater generated during water cooling is directly discharged, which wastes the dicing fluid. Therefore, a dicing fluid circulation device is needed.

[0003] Current chip dicing fluid circulation devices suffer from poor filtration efficiency. Impurities during fluid recovery can clog the pipes, further hindering filtration. Therefore, those skilled in the art have developed a chip dicing fluid circulation device to address the problems described in the background section. Utility Model Content

[0010] As a further improvement of this utility model: the top of the stainless steel ultrafine filter plate is in contact with the bottom of the metal filter frame, and handles are installed on both sides of the top of the metal filter frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the installation frame provides support and fixation for the activated carbon adsorption mesh, the stainless steel ultrafine filter mesh, and the metal filter frame. First, the sealing cover is moved out of one side of the circulation box, and then the metal filter frame is moved out of the circulation box by the handle, allowing for cleaning of the metal filter frame.

[0012] In this invention, the activated carbon adsorption mesh plate and the stainless steel ultrafine filter mesh plate are moved out of the circulation box by removing the metal filter mesh frame to one side, and then the activated carbon adsorption mesh plate and the stainless steel ultrafine filter mesh plate are moved out of the circulation box to the other side.
