Method and device for processing aluminum-based or aluminum alloy-based printed circuit board

Abstract

The invention provides a method and device for processing an aluminum-based or aluminum alloy-based printed circuit board. The method for processing the aluminum-based or aluminum alloy-based printed circuit board provided by the invention comprises the following step: when the printed circuit board is processed, cooling processing tools by utilizing a cooling liquid containing volatile substances and adhesives. By utilizing the method for processing the aluminum-based or aluminum alloy-based printed circuit board, the milling shaft of a milling machine for the aluminum-based or aluminum alloy-based printed circuit board can be effectively cooled without reducing the production efficiency, and the quality of the obtained aluminum-based or aluminum alloy-based printed circuit board can be improved.

Description

technical field [0001] The invention relates to the manufacture of a single-sided and multi-layer metal-based printed circuit board, in particular to a method for cooling the milling shaft of an aluminum-based or aluminum-alloy-based printed circuit board milling machine and a corresponding aluminum-based or aluminum-alloy-based printed circuit board. A cooling device for a milling shaft of a circuit board milling machine. In addition, the invention also relates to a processing method and a processing device for an aluminum-based or aluminum-alloy-based printed circuit board. Background technique [0002] With the rapid development of the electronic industry and the upgrading of electronic technology, the volume of electronic products is getting smaller and smaller, and the power density is getting higher and higher. How to find the best method for heat dissipation and structural design has become a huge problem in the design of today's electronic industry. challenge. Alumi...

AI Technical Summary

Problems solved by technology

In the absence of any auxiliary cooling measures, the following three problems will occur: the first problem is that the temperature of the milling shaft is too high, which will cause the machine to stop or burn the milling shaft directly; the second problem is that the temperature is too high The aluminum metal melts to form burrs, which affects the appearance of the product; the third problem is that due to the melting of the aluminum metal, the gong knife cannot discharge debris normally, causing the knife to break

However, these methods either reduce production efficiency or increase production costs.

[0006] Moreover, there is also a relatively serious problem in the existing aluminum-based or aluminum-alloy-based printed circuit board milling machine milling shaft cooling methods, that is, the periphery of the produced aluminum-based or aluminum-alloy-based printed circuit board is still There will be more glitches
