Aluminum PCB consists of a metal-based, copper-clad laminate that delivers high performance, including excellent thermal conductivity and electrical insulation.
A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric.
Benefits of Aluminum Core PCB
- Heat dissipation is dramatically superior to standard FR-4 constructions.
- The dielectrics used are typically 5 to 10 times as thermally conductive as conventional epoxy-glass and a tenth of the thickness
- Thermal transfer exponentially more efficient than a conventional Rigid PCB.
- Lower copper weights than suggested by the IPC heat-rise charts can be used.
- Environmental-friendly. Aluminum is a non-toxic, recyclable metal.
- Telecommunications, including high-frequency amplifiers and filtering appliances.
- Power Supply, for example, switching regulators and DC/AC converters.
- Automotive, including electronic regulators, lighting and power controllers, etc.
- Computers, such as CPU boards, floppy drives, and power devices.
- Power Modules, including converters, solid-state relays, power rectifiers, and bridges.
- Audio Devices, such as input and output amplifiers and power amplifiers.
- Office Automation, for example, electric motors and drives.
- Lamps and lighting: such as street lighting, traffic control lighting, interior building lights, landscape lighting, and camping gear, operating room lighting, surgical lighting tools, high power scanning technology, and power converters.
