Rigid-flexible printed circuit board,method for manufacturing same,and printed circuit board module

A rigid-flexible printed circuit board (PCB), comprising:

• a first flexible PCB having a first surface and a second surface opposite to, and substantially parallel to, the first surface, the first flexible PCB defining a first portion, a second portion, and a third portion connected in described order;
• a second flexible PCB having a first surface and a second surface opposite to, and substantially parallel to, the first surface, the second flexible PCB defining a fourth portion, a fifth portion, and a sixth portion connected in described order;
• a bonding sheet having a first surface and a second surface opposite to, and substantially parallel to, the first surface;
• the first surface of the third portion being adhered to the first surface of the bonding sheet, and the first surface of the sixth portion being adhered to the second surface of the bonding sheet, the fourth, fifth, and sixth portion of the second flexible PCB being separately aligned with the first, second, and third portion of the first flexible PCB;
• a first prepreg sheet adhered with the second surface of the first and third portion, and a second prepreg sheet adhered with the second surface of the fourth and sixth portion;
• a first conductive layers being adhered with a surface of the first prepreg sheet away from the first flexible PCB;
• and
• a second conductive layers being adhered with a surface of the second prepreg sheet away from the second flexible PCB;
• wherein the first and second portion of the first flexible circuit board are separated from the fourth and fifth portion of the second printed circuit board.
