The aluminum substrate is a low-alloy Al-Mg-Si high-plasticity alloy plate, which has good thermal conductivity, electrical insulation and machinability. Compared with the traditional FR-4, the aluminum substrate has the same thickness and the same line width, and can carry higher current. The aluminum substrate has a withstand voltage of 4,500 V and a thermal conductivity of more than 2.0, and is mainly used in the industry.
What are the characteristics of aluminum PCB substrate?
Features:
1. adopting surface mount technology (SMT);
2. In the circuit design scheme, the thermal diffusion is treated effectively;
3. Reduce the operating temperature of the product, improve the power density and reliability of the product, and prolong the service life of the product;
4. Reduce product volume, hardware and assembly costs.
Scope of application:
1. Audio equipment: input and output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc.
2. Power supply equipment: switching regulator, DC/AC converter, SW regulator, etc.
3. Communication electronic equipment: high-frequency amplifier, filter appliance and transmitting circuit.
4. Office automation equipment: motor drivers, etc.
5. Automobile: electronic regulator, igniter, power controller, etc.
6. Computer: CPU board, floppy disk drive, power supply unit, etc.
7. Power module: inverter `solid relay` rectifier bridge, etc.
Aluminum substrates are generally stored in a dark and dry environment. Most aluminum substrates are extremely prone to damp, yellow and black. Generally, they should be used within 48 hours after opening the vacuum package.
