ENIG automative flexible pcb blank pcb service for new energy vehicle special double-layer wiring fpcb with gold finger
New energy vehicles generally refer to vehicles that use unconventional automotive fuels as a power source, combined with advanced technologies in vehicle power control and driving, to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicle special flexible double-layer wiring products are made of polyimide or polyester film as a substrate, a highly reliable and excellently flexible printed circuit board. It has significant advantages such as high production efficiency, high wiring density, light weight, thin thickness, foldable and bendable, and three-dimensional wiring, which can realize energy and data transmission between modules. At present, new energy is expected to gradually replace traditional wiring harness solutions and become a mainstream trend. We can provide customers with special wiring ODM services.
