OEM Led Aluminum Pcb 2835 3030 Mcpcb for for led light
The basic structure of aluminum PCBs:
1. Circuit copper layer:
This layer consists of an electrolytic copper foil that ranges from 1 to 10oz. During its manufacture, the designer etches the copper material to form a printed circuit. Its function is to apprehend the assembly and connect devices for ease in functionality. It being an IMS, the substrate layer carries a higher current. Nonetheless, it still possesses a similar thickness and width to an FR-4 stiffener.
2. Insulating/ Dielectric layer:
The dielectric layer is best known for its thermal conduction. In thickness, manufacturers estimate them to be approximately 50µm to 200µm thick. It has the function of insulating, bonding, and dissipating heat from the board during current flow.t
3. Metal substrate:
Inarguably, this layer defines an IMS by totally distinguishing it from other PCBs. In other words, the insulating layer consists of a metal core made of an aluminum substrate. Factors you should consider when searching for a reliable metal plate are cost-effectiveness, strong point, firmness, mass, thermal coefficient, and most importantly, thermal conductivity.
With that said, an aluminum plate meets all the criteria above. Even better, you can enhance its efficiency in conductivity or mechanical properties by adding other leaves—for instance, copper, iron, and silicon steel plates.
4. The metal base membrane layer:
The base membrane, made of an aluminum alloy substrate, protects the aluminum substrate layer from unnecessary etching and scraping. Depending on the degree of heat, the coating can be lower than 120 or at 250. The layer commonly has a thickness of 1mm.

METAL CORE PCB APPLICATIONS:
PCBs that require a lot of power usually generate a lot of heat. If your PCBs need fast cooling it is better to use Metal Core PCB than FR4. The following list includes some of the most popular applications that work great with this technology:
- LED Lighting
- Power Conversion Systems
- Power Supplies
- Photovoltaics
- Telecom & Industrial
- Automotive Electronics
