Aluminum substrate is a "platform" used in circuit manufacturing, widely used in the LED lighting industry. It consists of a circuit layer, a metal base layer, and an insulation layer. Due to its excellent heat dissipation function, it has a good reputation in the electronic products, digital, mobile phones, and especially lighting fixtures industries.
Aluminum substrates often require cutting, drilling, and other processing techniques during the manufacturing process. Traditionally, external forces such as punching machines are used to achieve processing. However, due to the increasing demand for product quality in the market and strong competitiveness, in order to improve the quality level of products, refined processing can only be carried out in the production process, and more importantly, production efficiency needs to be improved.
The working principle of laser cutting aluminum substrate:
Laser has a good monochromatic line, which is directly irradiated onto an aluminum substrate in a non-contact manner using a beam of light. At this time, the aluminum substrate absorbs part of the energy of the laser, causing heat to be generated inside the aluminum substrate and the temperature to rise. Then, it melts or vaporizes, and finally achieves cutting or drilling. Of course, these operations require the cooperation of other auxiliary systems to complete such operations.
Advantages of using a professional aluminum substrate laser cutting machine:
1. The high laser power makes it easy to melt or vaporize hard and brittle materials, with fast speed, high efficiency, good cutting quality, no burrs, no carbonization, etc.
2. Adopting non-contact processing, there is no loss of other consumables such as cutting tools, molds, drill bits, or other consumables.
3. The beam spot is small and the heat affected area is small, making it suitable for the precision machining industry.
4. Due to the easy automation of laser output control, it can be used in conjunction with other modular subsystems for fast and precise processing, including laser cutting, cutting, heat treatment, welding, marking, drilling, etc!
