Aluminum PCB Fabrication

PCBBOX is offering aluminum PCBs to global customers with excellent quality and cost efficiency, which are widely applied in lighting projects. Aluminum PCBs are also known as metal-core PCBs, a type of printed circuit board that uses aluminum as the base material instead of the traditional fiberglass, with advantages:
1. Thermal Management: Aluminum PCBs have excellent heat dissipation properties, making them ideal for high-power applications.
2. Durability: The aluminum base provides mechanical stability and resistance to physical stress.
3. Lightweight: Aluminum is lighter than other metal bases, making it suitable for applications where weight is a concern.
