Description

Technical Field

[0001] The utility model relates to the technical field of aluminum substrate processing, in particular to a high thermal conductivity aluminum substrate manufacturing tool. Background Art

[0002] Compared with traditional FR-4 substrates, aluminum substrates have many obvious advantages, such as good insulation performance, high thermal conductivity, high resistivity and breakdown voltage, etc. These properties are of great significance for ensuring the performance of electronic products and extending their service life. In recent years, with the rapid development of power supply, LED lighting and automotive electronics industries, the application scope of aluminum substrates has been greatly promoted, and they have gradually replaced traditional resin circuit boards.

[0003] After searching, it was found that the application number is CN201610143764.5, and the name is a high thermal conductivity aluminum substrate. The application proposes a coating working principle and method for a high thermal conductivity aluminum substrate, and improves the thermal conductivity efficiency through the coating. At the same time, the application number is CN201911022158.8, and the name is a high thermal conductivity aluminum substrate production equipment. A stamping device for a high thermal conductivity aluminum substrate plate body is proposed, which is used to quickly prepare the plate body of the high thermal conductivity aluminum substrate. Combining the above two schemes, it is not difficult to see that the high thermal conductivity aluminum substrate is an aluminum substrate that is formed by stamping and then using paint. After the stamping is completed, a lot of burrs will remain on the surface of the aluminum substrate, which affects the use of the subsequent paint. It needs to be removed to make the surface smooth and facilitate the construction of the paint. The traditional polishing equipment uses a clamping device and a grinding device for polishing. The grinding equipment cannot grind the clamped part, and the staff needs to manually change the grinding surface, which is more troublesome and affects the production efficiency of the high thermal conductivity aluminum substrate. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
