Thick Copper PCB
Thick copper PCBs are printed circuit boards made using a special process to significantly increase the copper foil thickness to 3 ounces or more (up to 20 ounces). Their core features lie in their exceptional ability to carry high currents and dissipate heat efficiently, enabling them to meet the stringent requirements of high-power density designs and integrate complex circuits through a flexible stackup structure of 1 to 32 layers. These boards offer exceptional mechanical stability, a wide range of thicknesses (0.3 to 6 mm), and support drilling processes with aspect ratios up to 10:1, ensuring reliability in harsh electrical environments. Consequently, thick copper PCBs have become the preferred solution for high-power power supplies, automotive control systems, industrial power equipment, and new energy conversion systems, providing solid support for high-energy-consuming electronic devices.
