BEGETE 8.0W aluminum-clad copper clad laminate

Aluminum-clad copper clad laminate is a special kind of printed circuit board. Its substrate is metal (usually aluminum, copper, or other alloys), instead of the traditional epoxy fiberglass board. Metal-clad copper clad laminates are characterized by better heat dissipation performance and are mainly used in high-power lamps such as LED lighting, LED streetlights, and LED stage lighting, as well as automotive electronics and backlights.
