Thick copper PCB, that is, thick copper printed circuit board, is a special type of PCB, whose main feature is that the thickness of the copper foil is greater than or equal to 2 ounces (about 70μm).
Features of Thick Copper PCB:
1. High conductivity:Thick copper foil can carry larger current and meet the requirements of high current and high voltage.
2. Good heat dissipation:Thick copper foil can effectively reduce the temperature of the circuit board and improve the working efficiency and stability of electronic products.
3. High mechanical strength:Thick copper foil enhances the mechanical strength of the circuit board, enabling it to withstand greater mechanical stress.
4. High reliability:Thick copper PCB can still maintain stable circuit design and signal transmission in harsh environments (such as high temperature, low temperature, corrosion, etc.).
