A simplified pen core module and the preparation method thereof

This invention discloses a simplified pen core module and the preparation method thereof. The pen core module is characterized in that it adopts PCB board as the main body of pen core, and the PCB board is covered with FPC boards that serve as pins; a hollow threaded seat is sleeved at the strip part of the PCB board, and is electrically connected with and fixed at the root step of the strip part; a hollow metal cylinder and a hollow cone part are sleeved in sequence at the relative position of the strip part of the PCB board and, through the hollow interior thereof, electrically connected with the bonding pad of the PCB board and fixed at the relative position; a heat resisting insulation ring is sleeved between every two of the threaded seat, metal cylinder and cone part.
