Metal substrate
What kind of metal is used for the insulating metal substrate depends on the comprehensive consideration of the thermal expansion coefficient, thermal conductivity, strength, hardness, weight, surface state and cost of the metal substrate.
In general, considering the conditions such as cost and technical performance, aluminum plate is an ideal choice. Available aluminum plates are 6061, 5052, 1060 and so on. If there are higher requirements for thermal conductivity, mechanical properties, electrical properties and other special properties, copper plates, stainless steel plates, iron plates and silicon steel plates can also be used.
Application of Aluminum PCB
1. Audio device: Input, output amplifier, balanced amplifier, audio amplifier, pre-amplifier, power amplifier.
2. Power Supply: Switching regulator, DC / AC converter, SW regulator, etc.
3. Communication electronic equipment: High-frequency amplifier, filtering appliances, the transmitter circuit
4. Office automation equipment: Motor drive, etc.
5. Automobile: Electronic regulator, ignition, power supply controller, etc.
6. Computer: CPU board, floppy disk drive, power supply devices, etc.
7. Power Modules: Inverter, solid-state relays, rectifier bridges.
8. Lamps and lighting: As the advocated promotion of energy-saving lamps, a variety of colorful energy-saving LED lights are well received by the market, and aluminum PCB used in LED lights also begin large-scale applications.
