The aluminum substrate is a metal-based copper clad laminate with good heat dissipation performance. The general single board is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal substrate layer.

　　Characteristics of aluminum substrate

　　1, surface mount technology (SMT);

　　2. In the circuit design formula, the heat dissipation has been very effectively dealt with.

　　3. Reduce the operating temperature of the product, improve the power density and reliability of the product, and extend the service life of the product;

　　4. Reduce product volume, reduce hardware and assembly costs;

　　 5. Replace the fragile ceramic substrate to obtain the best mechanical durability.

　　PCB aluminum substrate use

　　1. Audio equipment: input and output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc.

　　2. Power supply equipment: switching regulators, DC/AC converters, SW regulators, etc.

　　3, communication electronic equipment: high-frequency amplifier filter electrical transmission circuit.

　　4. Office automation equipment: motor drives, etc.

　　 5. Automobile: electronic regulator, ignition, power controller, etc.

　　6. Computer: CPU board, floppy disk drive, power supply unit, etc.

　　7. Power modules: converters, solid state relays, rectifier bridges, etc.

　　 8. Lamp decoration: With the promotion of energy-saving lamps, aluminum substrates used in LED lamps have also begun to be applied on a large scale.
