Patent ID: 7875969

Claim:
A rigid-flex printed circuit board (PCB) with a weakening structure, comprising a rigid printed circuit board (RPCB) and a flexible printed circuit board (FPCB) that are bonded 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 an upward cut at a bottom surface of 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 an upward cut at the bottom surface of 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.
