Rigid-flex printed circuit board with weakening structure

A rigid-flex PCB with weakening structure, comprising a rigid printed circuit board (RPCB) and a flexible printed circuit board (FPCB) that together form a complete circuit board;

• the RPCB including:
• a connection section having a first lateral edge and an opposite second lateral edge;
• a first section extended from the first lateral edge of the connection section and having a FPCB bonding side, and a weakening structure being formed on the RPCB along the first lateral edge of the connection section by upward cutting the RPCB in a direction perpendicular to the FPCB bonding side of the first section;
• and
• a second section extended from the second lateral edge of the connection section and having a FPCB bonding side, and a weakening structure being formed on the RPCB along the second side lateral edge of the connection section by upward cutting the RPCB in a direction perpendicular to the FPCB bonding side of the second section;
• and
• the FPCB including:
• a bending section corresponding to the connection section on the RPCB, and having a first lateral edge and an opposite second lateral edge;
• a first section extended from the first lateral edge of the bending section, and having a RPCB bonding side corresponding to the FPCB bonding side of the first section of the RPCB;
• and
• a second section extended from the second lateral edge of the bending section, and having a RPCB bonding side corresponding to the FPCB bonding side of the second section of the RPCB.
