    摘要: The present disclosure provides a printed circuit board and a manufacturing method of the printed circuit board. The manufacturing method may include: at least two core plates may be provided; a composite anti-glue film assembly may be arranged at a preset position of one of the at least two core plates, the composite anti-glue film assembly may include a first anti-glue film layer, a second anti-glue film layer and a bonding layer. The first anti-glue film layer may contact the preset position. The first anti-glue film layer may be a polyimide layer. The bonding layer may be configured to bond the first anti-glue film layer and the second anti-glue film layer together to produce the composite anti-glue film assembly. Two adjacent core plates may be connected through a medium layer. The core plates may be cut-out and form the printed circuit board.
