Single Sided DOB LED PCB Circuit Board For 9W 18W LED Bulbs Light mcpcb

Copper Layer: At the top of the aluminum PCB, there is a copper layer, which creates the circuit. The layer is common in all types of PCBs, including FR-4. It offers the electrical connection and conductivity of current among the components.

Dielectric Layer: Aluminum can also conduct electricity; therefore, a dielectric material is used between the copper layer and the aluminum layer. This layer can be of different materials depending on the temperature range. Although this layer is electrically insulated, it can conduct heat efficiently. It has excellent thermal conductivity to hold the heat from the components to the aluminum layer.

Aluminum Base Layer: This is the most crucial layer of the PCB. It provides thermal conductivity, durability, and strength to the PCB. The layer is made of aluminum substrate. The substrate can be of different types, such as Aluminum 505, Aluminum 6061, etc. You can choose the perfect aluminum substrate according to your requirements.

Aluminum Base Membrane Layer: The aluminum base film is selective. It has a protective effect by protecting the aluminum surface from scratches and unnecessary corrosion. It has two types, namely less than 120 degrees or about 250 degrees (high-temperature resistance)
