Aluminum PCB is one type of metal core printed circuit board (MCPCB), widely be used in LED lighting industry.
If you are looking for Aluminum PCB Manufacturer, MORE PCB LTD has rich experience in manufacturing Aluminium PCB with high thermal conductivity , we offers a first class service and extensive high-tech options.
MCPCB, Metal Core PCB, thermal PCB – whichever name you prefer, they are all boards which use a base metal material as the heat spreader portion of the circuit board.These types of are typically fabricated with a metal base consisting of aluminum (most common) but can also be produced with copper.
Applications of Aluminum PCB:
- General lighting applications (Streetlight , Flashlight, Spotlight, etc.)
- Back light unit applications
- System automotive LED applications
- Power converters: telecom, high voltage regulator, power supplies
- Hybrid/electric motor control applications
Aluminium PCB Stack Up details as the drawing.
1. Aluminium PCB Copper Traces Layer
The copper circuit (traces) layer is etched to form the printed circuit, Compared to FR4 material,
Aluminium PCB can bear higher electric current when same thick circuit layer and same trace width.
2. Aluminium PCB Dielectic Layer
The dielectic layer is the core technology of the Aluminium PCB, which mainly serves as the function of adhesion, insulation and heat conduction.
The better the thermal conductivity of insulation is, the quicker the components spread the heat when they work, which can realize the purpose like improving power loading of the modules,reducing volume, extending life span and increase the output power.
3. Aluminium PCB Metal Substrate Layer
Usually, considering the cost and technical characteristic, aluminium is the ideal choice. The available aluminum plates are 6061,5052,1060 etc.
If there is a higher heat transfer performance, mechanical properties, electrical properties and other special performance requirements, copper, stainless steel plate, iron plate, silicon steel plate, etc can also be used.
