[0002] Aluminum nitride substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided board is composed of a three-layer structure, namely a circuit layer (copper foil), an insulating layer and a metal base layer. It is commonly used in LED lighting products. It has two sides, the white side is for welding LED pins, and the other side is the original color of aluminum. Generally, it will be coated with thermal conductive slurry and then contact the thermal conductive part. There are also ceramic substrates, etc. Aluminum substrates need to be punched with a laser punching machine during the production process.

During the drilling process, the laser drilling machine itself generates a large amount of heat when working, and the temperature of the workpiece increases during drilling, which increases the temperature of the workpiece and the surrounding area of ​​the drilling machine. As a result, the heat of the laser drilling machine cannot be dissipated from all sides, and the heat dissipation efficiency is low. Utility Model Content
