For example, it can be freely bent, rolled, folded. The FPC can be used for greatly reducing the volume of electronic products, and is suitable for the development of the electronic products in the directions of high density, miniaturization and high reliability. A plurality of rectangular metal contact pieces are arranged in rows at positions close to the board edges on the printed circuit board, and the metal contact pieces are formed by electroplating a layer of nickel-gold on the copper surface of the printed circuit board. These metal contacts are part of the printed circuit board and are called gold fingers because their surfaces are plated with nickel and gold and are shaped like fingers. The golden fingers are used for connection between printed circuit boards, and can connect circuits and transmit signals. The nickel layer on the surface of the golden finger can improve the plugging resistance, the conductivity and the oxidation resistance of the part. The golden fingers are generally divided into isometric golden fingers, grading golden fingers and segmentation golden fingers, the grading and segmentation golden fingers break through the original design concept of the golden fingers in design, and the golden fingers are designed into structures with different lengths or segments, so that an effective time difference is formed in the signal transmission process, the transmission of high-frequency signals is facilitated, an electrified hot plugging technology can be realized, and great convenience is brought to subsequent upgrading and maintenance.
