The circuit board can be called printed circuit board or printed circuit board. The birth and development of the soft and hard combination board gave birth to a new product, the soft and hard combination board. Therefore, the soft and hard combination board is the combination of flexible circuit board and hard circuit board through pressing and other processes according to the requirements of relevant processes to form a circuit board.

[0004] The authorized publication number "CN109168261B" records "a cutting device for mobile phone circuit board production, comprising a bottom plate and a mobile phone circuit board body, the top of the bottom plate is fixedly connected with a fixed box, the top of the fixed box is slidably connected with a mounting plate, one side of the top of the mounting plate is fixedly connected with a fixed plate, the front of the fixed plate is fixedly connected with an electric telescopic rod on both sides, one end of the electric telescopic rod is fixedly connected with a fixed frame, the top of the mounting plate and the two sides of the mobile phone circuit board body are fixedly connected with a horizontal plate through a vertical rod, the opposite sides of the two horizontal plates are fixedly connected with a limiting block through a connecting rod, the top and bottom inner walls of the fixed frame are provided with a fixed groove, and the mobile phone circuit board production cutting device is used in the technical field of mobile phone circuit board.
