♦ 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.
