Metal PCB Board-Aluminum substrate

Metal PCB Board Aluminum Substrate High Density Display Light Board

Aluminum substrate is a metal base copper clad plate with good heat dissipation function, the general single panel is composed of three layers of structure, respectively, circuit layer (copper foil), insulation layer and metal base. For high-end use are also designed for double panels, the structure of the circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. Very few applications are multi-layer boards, which can be made of ordinary multi-layer boards and insulation layers and aluminum bases.
1, the advantages of aluminum substrate
(1) The heat dissipation is significantly better than the standard FR-4 structure.
(2) The thermal conductivity of the dielectric used is usually 5 to 10 times that of conventional epoxy glass, and the thickness is only one-tenth.
(3) The heat transfer index is more efficient than the traditional rigid PCB.
(4) A lower copper weight can be used than indicated in the IPC recommended figure.
2, the application field of aluminum substrate
(1) Audio equipment: input, output amplifier, balance amplifier, audio amplifier, preamplifier, power amplifier, etc.
(2) Power supply equipment: switch regulator, DC/AC converter, SW regulator, etc.
(3) Communication electronic equipment: high frequency amplifier, filter electrical equipment, transmission circuit.
(4) Office automation equipment: motor drives, etc.
(5) Automobile: electronic regulator, igniter, power controller, etc.
(6) Computer: CPU board, floppy disk drive, power supply device, etc.
(7) Power module: converter, solid relay, rectifier bridge, etc.
Aluminum substrate is widely used, general audio equipment, power equipment, communication electronic equipment, office automation equipment, automobiles, computers, power modules have aluminum substrate existence.
