32-layer 8OZ Thick Copper PCB for high-power electrical appliances

♦ What is Thick copper PCB?

Thick copper PCB refers to a circuit board formed by bonding a layer of copper foil with a thickness of 2 ounces (oz, about 62.5 microns) or more to FR-4 or other substrates during the printed circuit board (PCB) manufacturing process.

♦ Features of Thick Copper PCB

• • Excellent conductivity: Thick copper foil greatly improves conductivity, reduces impedance, meets the needs of high-current and high-frequency equipment, and improves circuit speed and reliability.

  • Strong load-bearing capacity: Thickening copper foil enhances mechanical strength and rigidity, can withstand higher physical pressure, bending and mechanical/thermal stress, and adapt to harsh environments.

  • Good heat dissipation: Thick copper layer quickly disperses heat, reduces thermal stress, ensures stable operation of high-power equipment and extends life.

  • High thermal stability: Efficient heat conduction reduces heat accumulation and maintains performance stability of equipment at high temperatures.

  • High design flexibility: Supports wider lines and smaller spacing to achieve complex and high-density circuit layout.

♦ Applications of Thick Copper PCB

• • ​​Power supply equipment: high-power switching power supply, inverter, UPS, etc.
  • ​​Automotive electronics: electric vehicle motor controller, on-board charger, battery management system.
  • ​​Industrial control: motor driver, servo controller, welding equipment.
  • ​​New energy field: photovoltaic inverter, wind power converter.
  • High-power LED lighting: LED driver board that needs heat dissipation and current carrying
