What is heavy copper PCB
Heavy copper PCB is a high -current PCB that contains 3 ounces or more copper in the external and inner layers of the circuit board. Even if the total amount of copper is less than 3 ounces, if the thickness of the copper of the PCB is greater than 4 ounces/square foot, it is also considered to be a heavy copper PCB. This large amount of copper is used as an alternative to increasing the degree of wiring.
The characteristics of heavy copper PCB
Compared with ordinary PCB boards, heavy copper PCB has the following characteristics:
1. Strong current carrying capacity: The copper foil of heavy copper PCB is large, so it can carry larger currents, which is suitable for some occasions that require high -current conduction.
2. Excellent heat dissipation performance: The heat guidance rate of heavy copper PCB is high, good heat dissipation performance, and is suitable for some electronic equipment that requires good heat dissipation effects.
3. Haute résistance mécanique: Due to the large thickness of copper foil, the mechanical strength of heavy copper PCB is relatively high, which can provide better mechanical support performance.
4. Good corrosion resistance: A layer of corrosion coating on the surface of the copper foil is plated, which enhances its corrosion resistance and extend the service life.

The manufacturing process of heavy copper PCB is similar to ordinary PCB boards, but it is different in the thickness and electroplating process of copper foil:
1. Selection of heavy copper foil: The thickness of copper foil of heavy copper PCB is usually above 70um, and it can reach hundreds of UM according to specific needs.
2. Preparatory processing process: grinding and oil removal of heavy copper foil, etc.. to ensure the flat surface and improve the adhesion.
3. Electroplating process: After the copper foil is treated with anode oxidation, the copper plating process is performed to increase the thickness of the copper foil.
4. Multi -layer pressure bumper: Multiple copper PCB plates are layed overlap, and high temperature and high voltage are used for pressing.
5. Final processing: including drilling, layer layer production, surface treatment and other steps, so that heavy copper PCB finished products meet the requirements.
