Custom Design Metal Core Aluminum PCB Board Fast Delivery 2.0W
Thermal Conductivity
Aluminium PCB
1. Aluminium PCB Circuit Layer
The circuit layer (commonly used electrolytic copper foil) 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 Insulating Layer /Dielectic Layer
The insulating 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.
Linked Electronics has rich experience in manufacturing aluminium
PCB with high thermal conductivity.
3. Aluminium PCB Metal Base 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.
