What are the characteristICs and applications of aluminum substrate?

Among all metal core PCBs commonly used in SMT chip factories, aluminum core PCBs are the most common type. The base material consists of aluminum core and standard FR4. It has a thermal coating, which can efficiently dissipate heat, cool components and improve the overall performance of the product. It is currently considered a solution for high power and tight tolerance applications.

Advantages of aluminum substrate

1. Environmental protection: aluminum is non-toxic and recyclable. The use of aluminum also saves energy because it is easy to assemble. For SMT chip factory, using this metal will help maintain the health of our planet.

2. Heat dissipation: High temperature will cause serious damage to electronic products, so it is wise to use materials that help heat dissipation. Aluminum can actually transfer heat away from important components, thereby minimizing the harmful effects it may have on the circuit board.

3. Higher durability: aluminum provides products with strength and durability that ceramic or glass fiber base cannot provide. Aluminum is a solid substrate. SMT chip manufacturers can reduce accidental damage during manufacturing, processing and daily use.

4. Lightweight: Due to its incredible durability, aluminum is an amazing lightweight metal in the SMT patch. Aluminum increases strength and elasticity without adding any additional weight.

5. Application of aluminum substrate

1. Audio equipment: input, output amplifier, balance 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, filter apparatus, transmitting circuit

4. Office automation equipment: motor drive, etc.

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

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

7. Power module: inverter, solid state relay, rectifier bridge.

8. Lamps and lighting: As the advocate of energy-saving lamps, various colorful energy-saving LED lamps are popular in the MARKet, and aluminum PCBs for LED lamps have also begun to be widely used.

Storage conditions 

Aluminum PCBs are usually stored in a dark, dry environment. Most aluminum PCBs are prone to moisture, yellowing and blackening. Generally, it should be used within 48 hours after opening the vacuum package.

2-layer aluminum PCB base plate, copper thickness 1oz, aluminum base plate at the bottom of the laminate is SIMilar, for reference. The above parameters are basically unchanged. The thickness of the aluminum substrate in the SMT processing factory is the thickness of the plate selected by the customer minus the thickness above.
