The Structure and Advantages of LED Circuit Boards:

As a circuit carrier specifically designed for LED light sources, the importance of LED circuit boards is self-evident. They are typically composed of a base plate, a circuit layer, electronic components, and areas where LED chips are soldered.

The selection of base plate materials is diverse, including glass fiber plates and metal base plates, etc. These materials provide stable mechanical support and a good heat dissipation foundation for the entire circuit board.

The circuit layer is responsible for precisely transmitting electrical energy to each LED chip, and the rationality of its design directly affects the light emission effect and overall performance of the LED.

The advantages of LED circuit boards are remarkable, featuring excellent energy-saving characteristics. Compared to traditional lighting sources, the energy consumption of LED circuit board-driven lamps is significantly reduced. At the same time, it has an extremely long service life, reducing the inconvenience and cost of frequent lamp replacements.

Characteristic of Aluminum:

RoHs Compliant
More suitable for SMT process;
In the circuit design scheme, the thermal diffusion is treated very effectively, thus reducing the operating temperature of the module, extending the service life, improving the power density and reliability;
Reduce the assembly of heat sinks and other hardware (including thermal interface materials), reduce product size, and reduce hardware and assembly costs; Optimal combination of power circuit and control circuit;

The aluminum substrate can reduce the thermal resistance to the minimum, so that the aluminum substrate has excellent thermal conductivity and excellent mechanical properties.

Aluminum PCB
Aluminum PCB for LED, also known as the metal base PCB, is a kind of PCB which comprises of thin dielectric thermally conductive as well as electrically protected layer and copper clad overlay that is overlaid between metal base and copper foil. The copper foil embraces the ideal circuit design while metal base permits the warmth disseminating with the assistance of dielectric put between the layers. The development for aluminum PCB is mostly separated into three layers.
