What is aluminium PCB board ?
Aluminium PCB board, also named Aluminium based PCB, metal clad (MCPCB) PCB, insulated metal substrate(IMS or IMPCB) PCB, thermally conductive PCBs, etc. Aluminum printed circuit board ( PCB ) is a unique metal-based copper clad laminate with good thermal conductivity, electrical insulation performance and mechanical processing performance. It is composed of copper foil, thermally conductive insulating layer and metal substrate. It is generally including single layer, double layer and multi layer aluminum pcb board.
The structure of aluminum printed circuit boards
Generally speaking, the PCB aluminum substrate is composed of a circuit layer, a thermally conductive insulating layer and a metal base layer; it can be divided into three layers:
Circuit layer: equivalent to the copper clad laminate of an ordinary PCB, the thickness of the circuit copper foil is 1 to 10 oz. The circuit layer (that is, copper foil) is usually etched to form a printed circuit to connect the various components of the assembly. Generally, the circuit layer requires a large current-carrying capacity, so thicker copper foil should be used, with a thickness of 35μm~ 280μm;
Insulation layer: The insulation layer is a layer of low thermal resistance thermally conductive insulating material. The thickness is 0.003 to 0.006 inches. It is generally composed of a special polymer filled with special ceramics. It has low thermal resistance, excellent viscoelasticity, thermal aging resistance, and can withstand mechanical and thermal stress. It is the core technology of aluminum-based copper clad laminates. Our aluminum printed circuit boards have obtained UL certification.
Metal base layer: The metal base layer is the support member of the aluminium pcb, which requires high thermal conductivity, generally aluminum plate will be used, copper plate can also be used (copper plate can provide better thermal conductivity), suitable for conventional machinery such as drilling, punching and cutting processing.
Main usages and applications of aluminium PCB board:
- Audio devices: input, output amplifiers, balanced amplifiers, audio amplifier, preamplifier, power amplifier etc.
- Power Supply: switching regulator, DC / AC converter, SW regulator .
- Telecommunications electronic equipment: high-frequency electric amplifiers, filtering appliance, transmitter circuit etc .
- Office automation equipment: electric motor, drivers etc .
- Automotive: electronic regulator, ignition, power controllers etc .
- Computer: CPU board, floppy drive, power device etc .
- Power Modules: converter, solid-state relay, power rectifier bridges etc .
- Lamps Lighting: with the promotion of energy-saving lamps, Aluminum base PCB , are widely used on LED lights.
Advantages of aluminum PCB printed circuit boards
- It is more suitable for SMT process;
- Meet the requirements of RoHs;
- The heat dissipation has been effectively treated, thereby reducing the operating temperature of the module, prolonging the service life and improving the reliability;
- The volume is decreasing, reducing the assembly area of radiators and other hardware, reducing product volume, and reducing hardware and assembly costs;
- Good mechanical durability, better than ceramic circuit boards made by some simple processes.
