A 6-layer immersion gold FR4 PCB board is a type of printed circuit board used in automotive electronics. It consists of six layers of FR4 material, which is a flame-retardant fiberglass epoxy laminate. The board is coated with a thin layer of immersion gold as a surface treatment. Immersion gold is a process that applies a very thin layer of gold to the surface of the PCB, providing corrosion resistance and facilitating soldering operations.
