Coil PCB, we know, electricity generated magnetic, magnetic generated electricity, the two complement each other, always accompanied. When a constant current flows through a wire, a constant magnetic field is always excited around the wire.
In PCB proofing, a layer of copper foil is bonded to the outer layer of FR-4. When the copper thickness is = 8oz, it is defined as a 8OZ heavy copper pcb. The 8OZ heavy copper pcb has excellent extension performance, high temperature, low temperature, and corrosion resistance, which allows electronic equipment products to have a longer service life, and also greatly helps the size of electronic equipment to be simplified. In particular, electronic products that need to run higher voltages and currents require 8OZ heavy copper pcb.
