Aluminum PCB

Aluminum PCB

Aluminium pcb are used for the thermal management of the circuit. The Solution to High power LEDs, parts for controls, power transducers etc. are often developed with aluminum core pcb.
Aluminium pcb advantages：
1. Excellent heat dissipation
2. Excellent dimensional stability
3. Good mechanical processing capability
4. Electromagnetic shielding

Influence of manufacturing process on LED Aluminum Board
1. The heat dissipation performance directly affects the service life of LED lights.

2. The condition of the copper layer on the substrate determines whether a short circuit or local voltage instability will result in excessive temperature.

3. The surface impedance coating not only prevents wear and oxidation, but also improves the light reflectivity. But it is easy to change color when encapsulated.

4. Resin packaging is the most critical link. Assembly errors and materials are the decisive factors.




Production environment:
antistatic clothing, wearing electrostatic ring, grounding wire, mostly clean production workshop.
